How Doctors Test for MS

It can be a challenge for doctors to diagnose multiple sclerosis (MS). There’s no single test that can prove you have it. And many conditions have symptoms that seem like those of MS.

A neurologist — a doctor who specializes in treating the disease — should be able to help. They’ll ask how you’re feeling and help you figure out if your symptoms mean you have MS or another problem.

What Do Doctors Look For?

MS can take some time and a number of tests to diagnose. It starts when you or your doctor notices certain signs or symptoms that could be MS. These might include:

• Numbness or tingling in the skin (typically, hands or feet)
• Unusual weakness in arms, legs, or fingers
• Slurred speech
• Stumbling or trouble walking
• Double vision or loss of color
• Flashing lights that others can’t see
• Eye pain that gets worse with movement
• Vision loss in one eye

When you first notice these symptoms, especially if they are serious, your doctor might need to rule out other causes like stroke, tumor, or pressure on the spinal cord. If the symptoms last more than a couple of days, even if they go away on their own, it may be time to see a neurologist who specializes in MS to speed up diagnosis and start treatment.

Continued

If your doctors suspect MS, they will look for further symptoms and signs that suggest MS. To make a final MS diagnosis, they will use several tools to try and do three things:

• Rule out any other conditions that could cause your symptoms
• Find damage to at least two spots on your brain
• Prove the damage happened at different points in time

What Are the Tools for Diagnosis?

The doctor will start by asking you about your medical history and your symptoms. They’ll also do a few tests to see if your brain and spinal cord are working as they should. These include:

MRI: This imaging test lets the doctor take a closer look at your brain. They can see changes caused by multiple sclerosis, like signs of inflammation in the deep parts of your brain or spinal cord.

Continued

But older people or those with high blood pressure and diabetes also can have the same kinds of spots on a brain MRI. So the doctor will consider other info, including your symptoms, along with the scan results or the enhancement of lesions before they make a diagnosis.

Continued

Also, an MRI result that says things are normal doesn’t rule out MS. You could be one of a small number of people who have lesions in places the scan can’t show.

Learn more about using MRI to diagnose MS.

Lumbar puncture: This test, which you may also hear called a spinal tap, checks the fluid that runs through your spinal column. Doctors use it to look for high levels of proteins and other substances that are signs of the disease. It can help diagnose MS, but it, too, isn’t absolute proof.

Know what to expect with a spinal tap to diagnose MS.

Evoked potentials: These electrical nerve tests can help doctors confirm if MS has affected the parts of your brain that help you see, hear, and feel. The doctor will place wires on your scalp to test your brain’s response as you watch a pattern on a video screen, hear a series of clicks, or get electrical pulses on your arm or leg.

Continued

Find out how evoked potential tests help reach an MS diagnosis.

Blood tests: They can’t diagnose MS, but the doctor will use them to look for substances in your blood that point to it. Most importantly, they can help your doctor rule out conditions that look like MS.

Get more information about other types of demyelinating disorders that look like MS.

Eye exam: An eye exam could reveal problems that MS sometimes causes. Your doctor will test how well you can see detail far away, your field of vision, eye muscle strength, and pressure inside the eyeball, among other things. Possible MS-related conditions might include:

• Optic neuritis: Damage to the optic nerve that often causes pain as well as blind spots surrounded by areas of normal vision
• Nystagmus: Eyes move rhythmically back and forth or up and down without conscious effort. May be due to nerve damage, especially in the brainstem or cerebellum.
• Diplopia: Double vision that happens due to damage to the nerve pathways that control the eyes. It can be an early symptom of MS.

After a Diagnosis

It may take a long time to figure out that you have MS. If you’ve been waiting years or months, the news might be a relief. Or it could be a huge shock. Either way, you’ll have concerns about what the disease means for your life and your family. That’s completely understandable.

Talk with others — your friends, your doctor, a support group, or a counselor — about your feelings. Your health care team can help you decide the best ways to treat your disease and live with it day to day. MS affects everyone differently, so what works for one person with the condition may not be what’s best for you.

Multiple sclerosis – Diagnosis – NHS

Tests for MS

Diagnosing MS is complicated because no single test can positively diagnose it. Other possible causes of your symptoms may need to be ruled out first.

It may also not be possible to confirm a diagnosis if you have had only 1 attack of MS-like symptoms.

A diagnosis can only be made with confidence once there’s evidence of at least 2 separate attacks, although this may include signs of attacks on an MRI scan that you may not realise you have had.

Some of the tests you may need to confirm MS are discussed below.

Neurological examination

Your neurologist will look for abnormalities, changes or weakness in your vision, eye movements, hand or leg strength, balance and co-ordination, speech and reflexes.

These may show whether your nerves are damaged in a way that might suggest MS. 

MRI scan

An MRI scan is a painless scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.

It can show whether there’s any damage or scarring of the myelin sheath (the layer surrounding your nerves) in your brain and spinal cord. Finding this can help confirm a diagnosis in most people with MS.

A standard MRI scanner is like a large tube or tunnel. The machine is noisy and some people feel claustrophobic while the scan is done. Tell your neurologist if you’re worried about this.

Newer scanners are more open and work quicker than those used in the past, and most people have scans without any problems. 

Evoked potential test

There are several types of evoked potential test. The most common type assesses how well the eyes work.

Light patterns are shown to the eyes while your brainwaves are monitored using small, sticky patches called electrodes placed on your head.

It’s a painless test and can show whether it takes your brain longer than normal to receive messages.

Lumbar puncture

A lumbar puncture is a procedure to remove a sample of your spinal fluid by inserting a needle into the lower back.

Spinal fluid is the fluid that surrounds your brain and spinal cord, and changes in the fluid can suggest problems with the nervous system.

The procedure is done under local anaesthetic, which means you’ll be awake, but the area the needle goes in will be numbed.

The sample is then tested for immune cells and antibodies, which is a sign that your immune system has been fighting a disease in your brain and spinal cord.

Lumbar punctures are very safe, but are often uncomfortable and can cause a headache that occasionally lasts for up to a few days.

A lumbar puncture will often be performed to provide extra information if your symptoms or scans are unusual.

Blood tests

Blood tests are usually performed to rule out other causes of your symptoms, such as vitamin deficiencies or a very rare, but potentially very similar, condition called neuromyelitis optica.

Diagnosing MS: How Is MS Diagnosed?

Understanding How Doctors Test for MS and Make a Diagnosis

Currently, no individual symptoms or single laboratory test can be used to diagnose a person with MS. Physicians must instead rely on several strategies to determine if enough criteria are met to confidently make a diagnosis and rule out other possible causes of symptoms the patient is experiencing. Some of these strategies for diagnosing MS include:

• Thorough examination of a patient’s medical history
• Magnetic resonance imaging (MRI)
• Evoked potential (EP) testing
• Spinal fluid analysis

Criteria for Diagnosing Multiple Sclerosis

To make a proper MS diagnosis, physicians must:

• Find evidence of damage in at least two separate areas of the central nervous system (CNS) – including the brain, spinal cord and optic nerves
• Find evidence of damage occurring at least one month apart
• Rule out all other possible diagnoses

The Revised McDonald Criteria makes the process easier and more efficient in diagnosing MS in new patients, even if they have only experienced one MS attack. The updated criteria include specific guidelines for MRI (magnetic resonance imaging), VEP (visual evoked potentials) and cerebrospinal fluid analysis to speed up MS diagnosis.

Tools Doctors Use to Test for MS

While there is no one definitive MS test, physicians use the following tools to help in diagnosing MS in patients:

MRI: MRI is the best imaging technology to detect scarring or MS plaques in different parts of the central nervous system (CNS). This test can also distinguish old MS plaques from those that are currently active or new.

Visual Evoked Potential (VEP): Evoked potential (EP) tests record the nervous system’s electrical response to stimulation to isolated sensory pathways – such as visual, auditory or general sensory. Because slowed response time is a result of damage to myelin, EPs can often find the existence of scarring along nerve pathways, something neurological exams may miss. Visual evoked potentials are found to be most useful in confirming MS diagnosis.

Blood Tests: Currently, there are no definitive blood tests for diagnosing MS, but they can be used to rule out other conditions that may mimic MS symptoms, including Lyme disease, collagen-vascular diseases, rare hereditary disorders and acquired immune deficiency syndrome (AIDS).

Multiple sclerosis (MS): Tests and diagnosis

Multiple sclerosis, or MS, is a disabling disorder of the central nervous system. A range of tests can help doctors identify and monitor MS, although no single test or symptom can confirm an MS diagnosis.

Doctors will combine several strategies to check whether a person meets the criteria for MS. Before making a diagnosis of MS, a doctor must exclude the possibility of other conditions. To do this, they may use MRIs, blood tests, and spinal fluid analysis.

It is essential that people with MS receive a prompt and accurate diagnosis. Nerve damage might occur from the very start of disease progression, so it is vital for people to start treatment as soon as possible.

When a person has MS, their immune system attacks myelin, which covers and protects the nerve cells. When the myelin is damaged, scar tissue, or sclerosis, develop, and this interrupts the nerve’s ability to send messages back and forth.

In this article, we look at the various strategies a doctor might use to diagnose MS.

No single test can identify MS, so doctors often find the disease challenging to diagnose

The questions the doctor asks, and the ability to critically examine the signs and symptoms a person presents is vital for reaching an accurate diagnosis. The doctor will perform tests to help them assess a person’s:

• emotional and psychological state
• language functions and speech
• movement, coordination, and balance
• vision, smell, taste, touch, and hearing

In addition to taking a thorough medical history and physical exam, the doctor may recommend some of the following diagnostic tests to help confirm the diagnosis.

Magnetic resonance imaging (MRI)

MS can cause scar tissue, or plaques, to develop on damaged nerves. An MRI allows the doctor to look for this scar tissue. These abnormal spots can sometimes indicate other conditions, such as migraine or high blood pressure.

The scan uses magnetic fields and radio waves rather than radiation. It measures the relative water content in tissues.

The myelin that protects nerve cells is fatty, and so repels water. When this protective coating incurs damage, it holds more water, which would be visible on an MRI scan.

A doctor must carefully examine an MRI scan to diagnose MS accurately.

Evoked potentials

An evoked potential is an electrical test of the nerve pathways. It can help a doctor determine which nerve pathways have incurred damage from MS.

The doctor will place wires on a person’s scalp and examine the brain’s response to specific experiences, such as watching a video screen, hearing a particular noise, or feeling certain sensations. Although the test is highly sensitive, it is harmless and typically painless.

Damaged myelin slows electrical conduction along nerve pathways. This test is particularly useful, as it can find damage in areas of the central nervous system (CNS) that is not responsible for any symptoms.

Lumbar puncture

A lumbar puncture, which doctors also call a spinal tap, is a procedure that involves obtaining cerebrospinal fluid (CSF). This liquid surrounds the brain and spinal cord and can play a vital role in diagnosing MS for some people.

To extract CSF, the doctor inserts a needle between bones in the lower spine. They withdraw fluid using a syringe and then test for antibodies and proteins that may signal an abnormal immune response, such as oligoclonal bands.

Doctors no longer use lumbar puncture as a first-line test. An experienced doctor will decide if a lumbar puncture is needed based on medical history and the outcome of a physical exam.

Blood testing

No blood test can diagnose MS individually.

However, the doctor may order blood testing to rule out other conditions that have similar symptoms.

Blood testing can rule out the following health problems:

When to see a doctor

Anyone experiencing any of the symptoms of MS should seek a prompt and thorough assessment from their doctor.

To confirm a diagnosis of MS, the doctor needs to find evidence of damage in more than one area of the CNS. The damage has to have occurred at least 1 month apart, and a doctor must rule out any other possible causes.

If MS is the cause of a person’s symptoms, they should begin treatment as soon as possible to restrict the amount and degree of nerve damage.

According to the Multiple Sclerosis Foundation, early signs and symptoms include:

numbness and tingling in the feet, legs, hands, arms, or face

vision problems, such as blurry or double vision, loss of vision or color contrast, and pain when moving the eye

• fatigue
• difficulty walking
• bladder problems
• sexual problems, for example, reduced sex drive or erectile dysfunction
• problems with memory or speech
• depression and emotional changes
• muscle spasms and tremors

However, symptoms vary from person to person and may change over the course of the disease. Symptoms can also vary depending on which nerves develop plaques and incur damage.

If any of these symptoms occur regularly, seek an evaluation with an MS specialist.

It is essential that people find a specialist who is familiar with treating MS. People with MS require a wide-ranging approach to managing the unpredictable symptoms and disease progression.

Many medications are available to slow disease progression and treat the symptoms associated with the relapsing forms of the disease.

However, only ocrelizumab (OCR) is available to treat primary progressive MS (PPMS).

The use of medications will vary from person to person and will depend on the symptoms, stage, and severity of the disease. Doctors will also prescribe medications to treat relapses as needed.

People with MS could consider taking part in a rehabilitation program that focuses on maintaining strength and function of the body muscles.

Finally, it’s important to work with a healthcare provider who recognizes the importance of emotional health and coping mechanisms and can provide the appropriate referrals.

Here, learn more about PPMS.

MS is not usually fatal. The primary concern for people with this condition is preserving their quality of life. Many people with the condition will be able to lead a full, active lifestyle.

Although MS is a progressive and often debilitating disease, only some people with MS have symptoms that will eventually progress to permanent disability and mobility issues.

Many advances in the treatment options for MS have occurred in the past decade. New disease-modifying therapies (DMT), such as siponimod (Mayzent) and cladribine (Mavenclad), slow disease progression and decrease disability in people with relapsing forms of MS.

Research continues and offers promising discoveries and treatment for all types of MS.

Poultry flocks are susceptible to respiratory infections caused by a number of pathogens, including Mycoplasma spp. Usually Mycoplasma spp. cause infections such as chronic respiratory disease, aerosacculitis, sinusitis, and synovitis. However, in many cases, the infection can only be identified by serological and cultural methods. To track the contact of the herd with pathogens of the genus Mycoplasma , blood serum is analyzed for antibodies to Mycoplasma .

How to fix Microsoft Office problems with MS Office Diagnostics

You are working on an important spreadsheet and Microsoft Excel is crashing. MS Office apps are not working and all we can do is hold hands or call support. But what if we could commit suicide a little and find the cause ourselves?

Sometimes the failure may not be in the Office suite, but in the internals of the computer itself. It could be caused by faulty RAM or a hard drive problem. Or maybe you were too lazy to install one of the released service packs.

Microsoft now offers its own doctor. Diagnostics The MC is a tool included with Microsoft Office 2007 that runs a series of tests that can alert you to problems and help you find solutions. You must have come across the detection and recovery features of Microsoft Office 2003; MS Office Diagnostics is like an MRI scan for an X-ray.This gives you a more thorough check of your system with better repair options.

MS Diagnostics determines the size of your system by performing these scans,

• Settings Diagnostics

Files and registry are scanned for crashes, usually caused by viruses and incorrect installations. This test can take up to 15 minutes or more as it enters the very nerve center of the computer.

• Disc Diagnostics

This diagnostic test scans your hard drive for potential problems. It looks at the Windows System Event Log and SMART (Self Monitoring, Analysis and Reporting Technology) feature of your hard drive, if available. This test is sure to let you know if the hard drive prepares to fail.

• Memory Diagnostics

This checks the stability of the RAM.

• Update Diagnostics

This is a check for updates – are all updates installed on your computer and Office? This is important, as official updates smooth out bugs and make the system more stable.This test is available only if checking for updates is enabled for the Office suite.

• Compatibility Diagnostics

Sometimes you may have different versions of the same Office application or conflicting DLL files may cause errors. A compatibility test checks this and identifies the problematic factor.

• Check for known solutions

This test uses Microsoft’s extensive database of crash incidents and possible solutions to suggest a similar one after reviewing the crash reports on your system.

Now let’s make a diagnosis “

While this sounds like a very serious job, in practice it is not. This is cheers for the friendliness of Microsoft. Close all open programs before running tests and avoid using your computer while testing.

1. MS Office Diagnostics can be found in the MS Office Tool Group menu.
2. An MS Office Diagnostic window will open informing the user that testing can take up to 15 minutes and connecting to Microsoft servers.Click on continue.
3. This window displays the tests that will be run. Start the scan by clicking Run Diagnostics.
4. Diagnostics will run one by one and notify you of any glitches found. Ideally, this should complete in less than 10-15 minutes if there are no errors.
5. At the end of the diagnostic run, a summary of the results is displayed. Here, perhaps, the only significant catch in the tool is that it does not give a specific error.The diagnostic tool can do some repair work for the installation. Clicking “Continue” will take you to Microsoft’s huge resource for problems and solutions. You can follow his recommendations to fix the error if the repair fails.

The above steps will diagnose the entire Office suite. To save time, you can speed up the process and test the tool in one Office application. For example,

• Diagnostics for MS Word can be accessed from: Microsoft Office Button – Word Options – Resources
  Likewise for MS Excel / MS Access / MS PowerPoint , The tool can be accessed from: Microsoft Office Button – Options [Office Suite ] – Resources

• For others like MS Outlook / MS Visio / MS SharePoint Designer / MS Project / MS Publisher , path: Help – Office Diagnostics

Note.If all of the above options do not allow you to open MS Diagnostics, you can access the application directly from its location – C: \ Program Files \ Common Files \ Microsoft Shared \ OFFICE12 \ offdiag. exe.

After running the MS Diagnostic Tool, the issue may or may not be resolved. But Microsoft Diagnostics includes a fast detection and fix mechanism that gives us a “crash” course in Office repair.

90,000 Tests confirming MS Diagnosis – dummies 2021

For multiple sclerosis (MS), the diagnosis is when the patient’s medical history and neurological examination show two episodes of demyelination that are separated in time and space.

However, since no diagnostic test is definitive, various screenings and exams, as well as magnetic resonance imaging (MRI) scans, are commonly used to confirm the initial diagnosis or to help the neurologist identify a second episode of demyelination (if not was seen from history or exam). These other tests can also help rule out other conditions that may masquerade as MS.

Callable Testing Potential for Confirmation MS

Evoked Potential (EP) Tests are recordings of the electrical response of the central nervous system to stimulation of specific nerve pathways (visual, auditory, and sensory) that are commonly affected in MS.

These electrical responses are recorded from brain waves using electrodes attached to your head. Since demyelination leads to a slower response time, EPs can sometimes indicate demyelination along the neural pathways, which is not obvious to the neurologist from medical history or neurological examination.

Of the three types of EP tests that neuroscientists use (visual, auditory, and sensory), the VEP test is generally considered the most useful in diagnosing MS because 80 percent of people with the disease have slowed down to respond to this test.So, if Susie’s VEP is abnormal, her neurologist has evidence of two separate areas of demyelination to help confirm the diagnosis of MS. But, if Susie’s VEP is normal, the doctor should continue to look for additional evidence of demyelination.

When you take the EP test, the technician applies gel (to increase electrical conductivity) and electrodes to your head and body at specific locations based on the type of reaction being recorded. For example, when visual-evoked responses are recorded, electrodes are placed in the back of the head on areas of the brain that register visual stimuli.For other EP tests, electrodes are placed at different points on the head and body.

Different incentives are supplied for each test. For example, a stroboscope or checkerboard pattern flashes for visual testing; a click noise or tone is delivered through headphones for an auditory test; and a mild electrical impulse is applied to the wrist or knee for a general sensory test.

The procedure, which takes approximately 45 minutes per test, is non-invasive and completely painless, with the exception of slight (and we mean mild) discomfort caused by the mild shock given to the sensory evoked potential test.

Lumbar puncture to confirm MS

Lumbar Puncture or LP (also known as Spinal Tap ) allows your neurologist to examine Cerebrospinal Fluid (CSF), which softens and protects your brain and spinal cord. The doctor obtains CSF by inserting a spinal needle into your lower spine, as shown here: The CSF is then analyzed for an abnormal immune response in the CNS. Specifically, a neurologist is looking for an increase in the production of certain immune proteins (IgG).Using a method called

protein electrophoresis , some of this IgG may appear as stripes or bands (referred to as oligoclonal groups ). Nearly 90 percent of MS patients have these groups, making them an important piece of evidence in the diagnostic process. Because other conditions can also lead to oligoclonal banding, and because 10-21% of people with MS may indeed have normal CSF results, LA alone cannot make a diagnosis.However, the results can help the neurologist build a case for the diagnosis of MS, or rule it out.

The

LP, which is usually not high on anyone’s list of fun things to do, can be done in about 20 minutes at your neurologist’s office. The doctor injects a local anesthetic into the back. He then inserts a spinal needle into the fluid-filled space that surrounds the nerves below the lower end of the spinal cord, draws out a small amount of CSF (we promise it really isn’t as bad as it sounds), and then asks if you straighten your legs.Immediately after removing the needle, the doctor presses on the puncture site and asks you to lie down for about 30-45 minutes. This waiting period helps reduce the risk of severe headache caused by internal CSF leakage that occurs after approximately 20 percent of LP procedures. The doctor also recommends rest and plenty of fluids after LP.

Blood tests to rule out problems other than MS

Although there are no specific blood tests for MS, blood tests can positively rule out other causes of neurological symptoms such as Lyme disease, collagen vascular disease, certain inherited disorders, and HIV / AIDS.

Creation of test systems for personalized treatment of oncological diseases

It is necessary to correctly assess the state of metabolism of xenobiotics (including drugs) individually for each patient, since the way of excretion of drugs lies through the biotransformation system.

For the purpose of adequate selection and dosage of drugs (improvement of pharmacotherapy), it is extremely important to diagnose the activity of cytochrome P450 isoenzymes (CYP450), which are responsible for more than 50% of the phase I-dependent metabolism of widely used drugs.The activity of different CYPs can be assessed simultaneously by administering a cocktail of selected drugs that are substrates of the respective enzymes, followed by collecting plasma samples in order to quantify the plasma concentration ratio between parent drugs and their metabolites.

Diagnostics of the activity of cytochrome P450 (CYP450) isoenzymes can be carried out using Combi Cap – capsules containing microcapsules of several drugs for phenotyping patients, which will make it possible to adequately select and dosing drugs in the treatment of diseases.

Problems of modern pharmacotherapy:

1. The effectiveness of modern pharmacotherapy, despite evidence-based medicine, does not exceed 60%;
2. Increase in the number of adverse drug reactions, including fatal ones;
3. At a standard dose, the concentration of some drugs varies widely in patients.

Project tasks:

• Creation of the CombiCap test system – a capsule containing microcapsules of several drugs for the correct assessment of the metabolic state of xenobiotics (including drugs) individually for each patient, which will make it possible to understand the individual activity of enzymes and select a personal drug and dose in the treatment of oncological diseases ;
• Implementation of such a diagnostic system in medical practice.

Diagnostic test helps determine menopausal status – immunology

The PicoAMH ELISA test measures the amount of anti-Müllerian hormone (AMH) in the blood (photo courtesy of Ansh Labs).

Menopause is the period in a woman’s life when her menstrual cycle stops and she stops being fertile. During the menopausal transition, the body’s production of estrogen and progesterone, two hormones produced by the ovaries, differ greatly.

After menopause, women enter postmenopause and become more vulnerable to heart disease and osteoporosis. It is important that women are aware of their stage of the menopausal transition and understand what additional health risks they may face and what preventive measures should be taken.

The United States Food and Drug Administration (FDA; Silver Spring, Maryland, USA) approved the sale of an enzyme-linked immunosorbent assay (ELISA) diagnostic test as an aid in determining a patient’s menopausal status. The FDA analyzed data provided by the sponsor, which included 690 women aged 42 to 62 who participated in the women’s Health Across the Nation, a multicenter longitudinal study.

The PicoAMH ELISA test (Ansh Labs; Webster, TX, USA) measures the amount of anti-Müllerian hormone (AMH) in the blood. AMH levels are a measure available to doctors to determine if a woman is approaching or has already reached her last menstrual cycle. The PicoAMH ELISA test is intended for use only in conjunction with other clinical assessments and laboratory findings. Data from an FDA review showed that the PicoAMH ELISA test performed reasonably well in determining blood AMH levels and identifying women who had their last menstrual cycle and women who had more than five years since their last cycle.

Physicians should carefully evaluate the results of the PicoAMH ELISA test in the context of full clinical work to ensure that contraceptive use is not stopped in women who have not yet reached menopause and that uterine bleeding due to endometrial cancer has not been missed as a diagnosis. The PicoAMH ELISA test should not be used to assess fertility status or to monitor or predict ovarian response in women undergoing or planning to undergo fertility treatment.

FDA Officer Courtney Lias, PhD, said: “A woman’s menopausal status diagnostic results may spark discussions about preventive care for women experiencing menopausal symptoms. This test, when used in conjunction with other clinical assessments and laboratory findings, may help in discussing preventive care such as ways to prevent loss of bone mineral density or the treatment of cardiovascular disease, the risk of which is known to increase after menopause. “

Automatic sample preparation system for extraction from DBS cards for serological tests for antibodies to SARS-CoV-2

CAMAG offers the CAMAG DBS-MS 500 HCT Autosampler for clinical diagnostic laboratories as a high-performance system using dry blood stain technology for serological diagnostics in patients for antibodies to SARS-CoV-2.

The coronavirus 2 (SARS-CoV-2) pandemic has reached exceptional proportions.Therefore, scientists around the world are investigating the process of developing immunity after infection, evaluating transmission patterns, creating and researching new vaccines and therapies. The formation and subsequent reduction in the level of human IgG and IgM antibodies to SARS-CoV-2 plays a decisive role in epidemiological studies. Several research groups have demonstrated that dry blood stain (DBS) blood sampling is a simple and inexpensive way to perform such serological testing.

Concept for the analysis of antibodies to SARS-CoV-2 using CAMAG DBS-MS 500 HCT

Application area

Autosampler CAMAG DBS-MS 500 HCT with CTC PAL module allows collecting extracts from DBS cards into sample vials or plates (for example, 96-well plates) for further processing (for example, IgG ELISA). It is a high-performance diagnostic laboratory system for testing large populations for SARS-CoV-2 antibodies in a simple and reliable workflow.

The possibility of sampling by the customer himself and sending them to a centralized laboratory is convenient and protects people from the risk of infection or spread of infection.

Commercially available consumables required for sampling on DBS cards are minimum:

• Alcohol swab for disinfection.
• DBS card.
• Scarifier.
• Instructions.

In addition, this sampling allows the use of regular postal sample dispatches for delivery to the laboratory without the need for sample refrigeration.

Recommended equipment

• Autosampler CAMAG DBS-MS 500 HCT.
• Robot CTC PAL for collecting fractions into vials or plates (eg 96-well plates).
• ELISA kit (e.g. KT-1032 from Epitope Diagnostics).
• Microplate reader (e.g. Tecan Sunrise).
• Multichannel pipette.

Optional:

• Replacement set for extraction head Ø 6 mm.
• Washer (e. g. Thermo Scientific Wellwash) or KT-1032 compatible workstation from Epitope Diagnostics.

Wiring diagram CAMAG DBS-MS 500 HCT with CTC PAL robot for collecting samples. Modules 1-3 (camera, hematocrit scanner and extractor) are built into the DBS-MS 500 HCT autosampler.

Samples

Samples of “dry blood spots” with a minimum volume of 10 µl (Ø ≥ 6mm) on DBS AutoCollect cards (85 x 53 mm). An accurate sampling by volume of blood is not required. Sample volume can be compensated using the hematocrit scanner built into the CAMAG DBS-MS 500 HCT.

Standards

Negative and positive controls are required to determine the thresholds.

Extraction of samples

To get started, DBS cards are loaded into the DBS-MS 500HCT, the names of all samples in the queue are entered in the program. A cycle is then started and each DBS card is first detected by a camera according to the spot quality criteria and barcode or label.

In the next module, the hematocrit is determined to compensate for the distribution of the spot before extraction, and then the extraction (direct elution from the center of the Ø 4 mm spot) is carried out directly into the 96-well plate.

To obtain a concentrated extract, which can be used in the future without additional operations, you need only 100 µl of buffer solution from the Epitope ELISA kit and 2-3 minutes / sample, depending on the duration of the washing program.

Results

In a pilot study, 13 authentic samples were analyzed and compared with rapid serological testing. Of these, 12 (92.3%) were identified correctly using the DBS method described here.One sample was determined to be false negative. Since the immune response is a time-dependent response, the 12 days from the onset of symptoms was most likely insufficient to generate a stable amount of IgG antibodies based on the applied signal threshold. Overall, the test configuration showed a specificity of 100% (6/6) and a sensitivity of 86% (6/7).

Storage stability was assessed by comparison after storage of an IgG positive liquid blood sample for 4 weeks at 4 ° C in an EDTA blood collection tube and on a DBS card that was placed in a mini grip plastic bag along with desiccant.
