What is a yeast infection?
What is bacterial vaginosis?

A nurse or doctor can tell if you have vaginitis, and help figure out why it happened. Vaginitis treatments vary depending on what’s causing the problem.

Do I have to go to the doctor if I have vaginitis?

If you have symptoms of vaginitis, it’s a good idea to see your nurse, doctor, or local Planned Parenthood health center. Vaginitis isn’t usually a major health problem, but if you don’t get it treated it can become serious.

There are many different causes of vaginitis, and STDs like gonorrhea and chlamydia can have symptoms that are really similar to vaginitis. Seeing a doctor is the best way to find out exactly what’s going on, so you can get the right treatment.

To see what’s causing your vaginitis, your doctor may do an exam, look at a sample of your vaginal discharge under a microscope, or do other tests, like a urine test.

If your doctor has diagnosed you with a vaginal yeast infections before and you’re having the same symptoms, you can try an over-the-counter yeast infection medicine. But if you’re not sure, see your doctor or go to a Planned Parenthood health center. And if you used an over-the-counter medicine but your symptoms don’t go away, see a doctor.

What are the treatments for vaginitis?

Vaginitis is usually easy to cure. The type of vaginitis treatment that’s best for you depends on:

what’s causing your vaginitis
how bad your symptoms are
whether you’re pregnant

If your vaginitis is caused by a yeast infection, bacterial vaginosis, or trich, your doctor may give you a prescription for creams, suppositories, vaginal tablets, or pills. You can also get medicated creams or suppositories for yeast infections (like Monistat) at the drugstore without a prescription. Trich is the only type of vaginitis that’s sexually transmitted. So if you have trich it’s very important for your sexual partners to get treated, too.

If your vaginitis is caused by an allergy or irritation, the symptoms will usually go away when you stop using whatever’s causing the problem. Sometimes you might need to use a cream to help clear up your vaginitis. In rare cases of really bad allergic reactions, you may need emergency medical help.

If your vaginitis is caused by low levels of estrogen, your doctor may give you a prescription for creams, pills, or vaginal rings that release estrogen into your body.

No matter what type of vaginitis treatment you need, make sure you:

Don’t use anybody else’s medicine. Even if your symptoms are similar, you may have a different infection or need a different kind of treatment.
Don’t use old medicine. It may not work anymore, and it could even make the infection worse.
Carefully follow your doctor’s instructions or the directions that come with your treatment.
Use ALL of your medicine. The infection can come back if you don’t take all your medicine, even if your symptoms stop and even if you have your period.
Go to a follow-up appointment with your doctor to make sure the treatment worked.

During your vaginitis treatment:

Don’t put anything in your vagina except medicine or tampons. Take a break from oral or vaginal sex until you feel better.
If you have your period, it’s okay to use tampons or menstrual cups, unless it’s the kind of medicine you put into your vagina. If that’s the case, use pads instead.
If you’re using gels or creams inside your vagina, you can use unscented pads or panty liners to help keep the medicine from leaking onto your clothes.

How can I ease irritating symptoms of vaginitis?

Even though vaginitis can be super itchy and irritating, try not to scratch. It can cause more irritation or cuts in your skin, which can spread germs and lead to more infection. There are over-the-counter vaginal creams that you can use on your vulva to help calm the irritation. Your doctor can also give you tips on relieving burning and itching.

Avoid sex until your infection or irritation goes away (especially if you have trich, because it’s a sexually transmitted infection that you and your partner can pass back and forth). Friction from sex and your partner’s body fluids can cause more irritation or make it harder to heal. And some medicines that you use in your vagina have oil in them, which can cause condoms to break.

Where can I get checked and treated for vaginitis?

You can get checked and treated for vaginitis at your local Planned Parenthood health center, community or reproductive health clinics, or your ob/gyn or family doctor.

3 Best At-Home Yeast Infection Tests of 2022

Test Quick Guide

Vaginal yeast infections are a common cause of vaginitis and vulvovaginitis, a condition in which the vagina and/or vulva becomes inflamed and irritated. Vaginitis is usually caused by an imbalance of normal vaginal microorganisms resulting in an overgrowth of vaginal yeast. Certain sexually transmitted diseases (STDs) can cause similar symptoms. Vaginal yeast infections are most often seen in patients that are immunosuppressed, have diabetes, are pregnant, or have recently used a broad-spectrum antibiotic.

At-home yeast infection tests enable you to narrow down the possible causes of vaginitis. These tests use a sample of vaginal discharge to provide information about possible causes of vaginitis and facilitate a conversation with your doctor or gynecologist.

Testing for yeast with an at-home test is not as thorough as testing done at a clinic or doctor’s office, and at-home testing is not a replacement for medical care administered by a professional.

About the Test

Purpose of the test

The purpose of yeast infection testing is to determine if vaginitis is caused by yeast or by a different microorganism such as bacteria or some other organism associated with a sexually transmitted disease.

Vaginitis often causes uncomfortable vaginal symptoms such as:

Itching
Irritation
Pain during sex or when urinating
Burning
Swelling
Vaginal discharge

There are several options when looking for a cause of vaginitis, including physician-ordered and at-home tests. The following information describes the purposes of at-home and physician-ordered vaginal yeast infection tests.

Purpose of an at-home vaginal yeast infection test

An at-home yeast infection test allows you to look for evidence of a vaginal yeast infection in the privacy of your home. There are several types of at-home yeast infection tests that are available for purchase, including vaginal pH test strips and self-collection kits that allow you to collect a sample at home and mail it to a laboratory for nucleic acid amplification testing (NAAT).

Although these at-home tests can provide information about whether a yeast infection is the likely cause of your symptoms, determining the cause of vaginal symptoms should be done by a trained professional. Doctors have access to additional tests that may be used to accurately diagnose the cause of your symptoms.

Purpose of a physician-ordered vaginal yeast test

Physician-ordered vaginal yeast infection testing is performed to diagnose the cause of vaginitis so that appropriate treatment can be started.

To diagnose the cause of vaginitis, your doctor may ask about your symptoms, examine the affected area, and take a sample of vaginal discharge. Several tests may be conducted on this sample of vaginal discharge that help to determine the cause of your symptoms.

What does the test measure?

Vaginal yeast infections are caused by a type of fungus called Candida. Small amounts of Candida are normally present in your mouth, digestive tract, and skin. Also, small amounts of yeast can be found in your vagina without causing any symptoms.

Under normal circumstances, Candida and other microscopic organisms in the vagina keep each other in balance. However, a yeast infection may occur if conditions change in a way that promotes an overgrowth of yeast. This abnormal overgrowth of yeast can lead to uncomfortable symptoms.

Yeast is not the only disorder that can cause symptoms of vaginitis. Other common types of vaginal infections include bacterial vaginosis (BV) and a sexually transmitted parasite called trichomonas that causes trichomoniasis. While most vaginitis is caused by infections, other causes of symptoms include chemical irritations and low hormone levels.

There are a number of commercially available at-home tests that provide information about the cause of vaginitis. The two types of tests available are described in the following sections.

At-home vaginal pH testing

A number of at-home vaginal tests use pH testing to provide information about whether your symptoms are likely caused by an infection.

A measurement of vaginal pH describes the acidity of vaginal discharge on a scale ranging from 1 to 14. Lower numbers indicate that a substance is more acidic. The normal environment of the vagina is relatively acidic, with a normal pH of 4.0 to 4.5 for people during their fertile years. Vaginal yeast infections are generally associated with a normal vaginal pH, while trichomoniasis and bacterial vaginosis tend to cause a high vaginal pH. At-home pH tests can help you rule out these non-yeast causes of vaginitis.

Knowing the pH of your vaginal discharge may help narrow down what underlying problem is causing vaginal symptoms. However, changes or increases in your vaginal pH do not always indicate that you have a vaginal infection, so it’s important to discuss your results with a doctor or gynecologist.

At-Home NAAT Testing

Some at-home vaginitis tests use nucleic acid amplification testing (NAAT) in a laboratory to determine if vaginitis is caused by yeast or something else. This test method analyzes the DNA and RNA in samples of vaginal discharge to identify bacteria, fungi, or parasites. DNA and RNA carry genetic information for living things, including microorganisms that cause infection.

At-home vaginal yeast infection tests that use NAAT testing may focus on detecting just one type of infection or several potential causes of vaginitis. In addition to yeast, they may look for bacteria and sexually transmitted diseases that cause similar symptoms, such as trichomoniasis, chlamydia, and gonorrhea.

It’s important to check the product information accompanying your test kit to find out exactly which microorganisms it can detect.

When should I get an at-home vaginal yeast test?

There are no expert guidelines for when it’s appropriate to use an at-home vaginal yeast infection test. If you have symptoms of vaginitis (inflammation of vagina) or vulvovaginitis (inflammation of both vagina and vulva), it is best to see a health care provider. If getting in to see a doctor or nurse promptly is difficult, at-home vaginal yeast infection tests can provide information about whether your vaginal symptoms may be caused by an infection.

At-home vaginal yeast testing can not detect all cases of vaginitis. It is important to talk to your health care provider about your symptoms in order to access appropriate testing and treatment.

Benefits and Downsides of At-Home Vaginal Yeast Test

Every medical test is associated with risks and benefits. Learning about the pros and cons of at-home vaginal yeast testing may help you decide whether at-home testing is the right approach for you.

The potential benefits of at-home vaginal yeast testing include:

Privacy and convenience: At-home vaginal yeast test kits allow you to conduct testing at your home.
Easy sample collection: At-home test samples can be easily self-collected.
Combining with STD tests: Some at-home vaginal yeast infection tests offer panels or packages of tests that include tests for vaginal yeast infections and common STDs, allowing people to screen for STDs using the same test samples.
Transparent pricing: The costs of testing in a medical setting may be uncertain and depend on what and how many tests are performed. With at-home testing, your out-of-pocket costs are clear.

The potential risks of at-home yeast infection testing include:

Limited test options: When you have vaginal yeast testing in a medical setting, multiple tests may be done, including a physical exam, examination under a microscope of vaginal discharge, and a culture, if needed. These options are not available through at-home testing.
pH testing is of limited value for some people: The normal vaginal pH is higher in people before they are old enough to menstruate as well as after menopause. Because of this, testing pH is of limited value for people in these age groups.
Overdiagnosis and overtreatment: Because vaginal pH is not a conclusive test, at-home vaginal pH tests may lead people to use treatments for vaginal yeast infections that they don’t need.
Additional testing may be required: Patients who receive abnormal test results on an at-home vaginal yeast test may need to have the test repeated through a doctor’s office or laboratory.

Types of At-Home Vaginal Yeast Tests

Commercially available at-home vaginal yeast infection tests either measure vaginal pH or use NAAT technology to detect the presence of yeast, bacteria, or sexually transmitted disease.

Interpreting At-Home Vaginal Yeast Test Results

Interpreting your at-home vaginal yeast test result depends upon what kind of test is used.

Interpreting a vaginal pH test requires comparing a test strip to a color chart included with your kit. After testing your sample of vaginal discharge, you can immediately compare the color to the test kit and find your vaginal pH.

A pH in the normal range indicates that vaginal yeast is a potential cause of your symptoms. While results indicating a normal vaginal pH in the presence of symptoms of vaginitis suggest that you may have a yeast infection, it is possible that your symptoms are caused by something else. You should contact your doctor to discuss whether to make an office appointment for additional testing.

An abnormal result showing an elevated pH could be caused by several conditions, including:

Bacterial vaginosis (BV)
Trichomoniasis
Having both BV and a yeast infection at the same time

Regardless of your vaginal pH test result, it is important to contact your health care provider to discuss any vaginal symptoms that you’re experiencing.

If you purchase an NAAT test kit, you will be able to view your test results on a secure online platform after your sample is received and analyzed in the lab. Test results will indicate which microorganisms were tested and whether they were detected or not detected.

If microorganisms are not detected, your report may indicate that your results are normal. If microorganisms are detected, your results may be described as abnormal.

It’s important to talk to your doctor about the results of at-home NAAT testing. The company that provided your test kit may also help arrange a consultation with a health professional.

Are test results accurate?

Research has shown that self-testing vaginal pH as well as collecting samples at home for NAAT testing are similar in accuracy to testing performed by health care providers. However, at-home vaginal yeast infection testing is not a replacement for physician-ordered tests and you should talk to your doctor before treating a suspected yeast infection.

It is also important to follow the instructions that come with your test kit carefully. Sometimes pH testing is inaccurate because certain substances, including medications used in the vagina, menstrual blood, semen, douches, and lubricants, can temporarily raise vaginal pH.

Do I need follow-up tests?

A health care provider may recommend retesting to confirm the results of an at-home vaginal yeast infection test. Your health care provider may also wish to order additional tests that can only be performed in a medical setting, such as examining vaginal discharge under a microscope or performing a culture of vaginal discharge.

Follow-up testing may also be recommended if your symptoms persist or come back after treatment for a vaginal yeast infection.

Questions for your doctor after at-home vaginal yeast testing

After taking an at-home vaginal yeast infection test, it is important to speak with your health care provider about the test results. Questions that might be helpful include:

What does my at-home vaginal yeast infection test result mean about my health?
Are any follow-up tests needed to confirm my at-home test results?
Is there anything that I can do to reduce my risk of yeast infections?

At-home vaginal yeast infection testing vs. physician-ordered vaginal yeast infection testing

Yeast infection testing uses samples of vaginal discharge to diagnose the cause of symptoms related to vaginitis. At-home and physician-ordered testing differs in several ways, including the type of tests available and the established role of each approach.

When testing is performed by a medical provider, the provider is able to choose from a variety of tests based on a patient’s symptoms and the results of a physical exam. In contrast, at-home testing options are limited to vaginal pH and NAAT testing.

Although some at-home test companies facilitate access to a medical professional after abnormal test results, these consultations are usually restricted to discussing the test result. When vaginal yeast infection testing is performed by a medical professional, visits typically include further guidance related to your reproductive and sexual health.

One of the most important differences between at-home and physician-ordered tests is their established medical role. Although research suggests that the accuracy of at-home tests may be comparable to testing conducted by a medical provider, there are few guidelines regarding the appropriate use of at-home vaginal yeast infection tests.

Yeast infections (fungus) in women

Every woman will experience a yeast infection at some point in her life. A yeast infection is an irritating infection of the vagina and vulva that causes itching, discharge, and irritation. This is a type of vaginitis caused by an overgrowth of a yeast known as Candida albicans and is often easily treated at home, but can sometimes be severe enough to require a visit to a doctor.

On average, three out of four women experience a yeast infection. Some women have several throughout their lives. Although this disease is not considered a sexually transmitted disease, the fungus can be spread through oral contact with the female genitalia. It is important to be aware of the signs and symptoms of a yeast infection and when you should see your OB/GYN.

Signs and symptoms of yeast infections

Signs and symptoms of a vaginal yeast infection can range from mild to more severe. These include the following:

burning sensation, especially when urinating or during intercourse;
itching and irritation in the vagina and vulva;
redness and swelling of the vulva;
thick, white or greyish vaginal discharge resembling cottage cheese;
vaginal rash;
pain and soreness in the vagina;
watery vaginal discharge.

Yeast infection risk factors

There are certain risk factors that can lead to the development of a yeast infection. These include the following:

taking antibiotics;
lack of sleep;
hormonal imbalance during the menstrual cycle;
taking hormone therapy or oral contraceptives;
stress;
malnutrition, especially when eating too many sugary foods;
pregnancy;
diabetes;
weakened immune system;
wearing clothes that are too tight.

A yeast infection can be caused by a number of reasons, but the most common cause is the fungus Candida albicans. The vagina has a natural balance of this substance, as well as other bacteria. However, in some cases there may be an overgrowth of Candida, leading to the development of a yeast infection. As a result, you may experience a combination of classic symptoms such as burning, itching, and soreness. Even women who are not sexually active can develop this infection.

Sometimes other types of Candida can also cause a yeast infection, but most drugs, especially over-the-counter ones, are for Candida albicans. If you develop a yeast infection caused by another type of Candida, treatment may be more difficult. If more aggressive treatment is needed, you may need to make an appointment with an OB/GYN.

Diagnosis of yeast infections

When you visit your OB/GYN, the doctor will run a test to determine if you have a yeast infection:

Review of medical history, including any past vaginal infections or sexually transmitted diseases.
Visual examination of the pelvis, external and internal parts of the vagina.
Biosampling, a sample of vaginal secretions, to determine what type of fungus is causing the infection.

Yeast infection treatment

Treatment for a simple yeast infection is usually straightforward for most women and may include the following options:

Prescription antifungal cream, ointment, suppositories, or tablets that last one, three, or seven days.
Single dose oral preparations
An over-the-counter antifungal cream or suppository that lasts three to seven days.

For more complex yeast infections, a doctor may suggest the following treatment options:

Prescription antifungal cream, ointment, suppositories, or tablets that last up to 14 days.
Multi-dose oral preparations.
Maintenance plan for recurrent yeast infections. (This type of treatment usually lasts longer than 14 days and may require oral medication once a week for six months or vaginal suppositories once a week.)

Visit your obstetrician-gynecologist. A yeast infection can be uncomfortable and affect your emotional state, but the problem is treatable. Check with your doctor so you can take action in time to avoid infection in the future.

What is a yeast infection?

Most healthy women have yeast in their vagina. But sometimes the yeast grows too strong and leads to infection. Yeast infections can be very annoying and unpleasant.

What causes yeast infections?

Vaginal yeast infection, also sometimes called vulvovaginal candidiasis, occurs when the healthy yeast that normally lives in the vagina gets out of control. This often results in itching and other annoying symptoms. The medical name for a yeast infection is “ candidiasis ” because they are usually caused by a type of yeast called candida.

When the immune system is reduced, the normal yeast that lives in the vagina can grow too large and lead to infection. Causes that may cause changes in your vaginal environment:

normal changes in hormone levels (as during the menstrual cycle)
antibiotics, cortisone and other drugs
pregnancy
diabetes mellitus
weak immune system
natural reaction to another person’s genital chemistry

Yeast infections can also occur on the penises and scrotum, but not as often. They can cause redness and irritation on your penis or scrotum.

Yeast infections are not STDs (these are infections that are passed from one person to another during vaginal, anal and oral sex). They are not contagious and cannot be passed on to another person during sex. But sexual contact sometimes leads to yeast infections—your body chemistry can react to the other person’s natural genital yeast and the bacteria that causes the yeast to grow.

People can also get a yeast infection in their mouth, throat, or tongue—this is called thrush.

What are the symptoms of a yeast infection?

Yeast infections often cause a curdled, white, lumpy vaginal discharge that usually does not smell (or smells only slightly different than usual).

Most yeast infections result in itching, burning and/or redness in or around the vagina. Vaginal itching usually gets worse the longer you have the infection. Sex may be uncomfortable or painful. In extreme cases, you may get cracks or sores on your vagina or vulva. If you have severe irritation, you may experience pain when urinating.

How to treat yeast infections?

Yeast infections can usually be easily treated in a few days with an antifungal medication. You can purchase medicated creams or suppositories for yeast infections.

Be sure to follow instructions and take all medicines, even if your symptoms go away before you are done. You can also treat yeast infections with one tablet (diflucan or fluconazole). Need a prescription from a doctor to get a yeast infection pill.

Do not have vaginal or oral sex until you have completed treatment and the infection has gone. Friction from sex may cause more irritation or make treatment more difficult. Some medications you use inside your vagina contain oil, which can cause condoms to break.

Even though yeast infections can be very itchy, try not to scratch the itch. This can aggravate irritation or scratch the skin, through which germs can spread and lead to more infections. There are over-the-counter creams that can be used on the vulva to soothe irritation. Your doctor can also give you tips to relieve burning and itching.
