Microcytic anemia means that you have smaller red blood cells than typical — and fewer of them. It can result from an iron deficiency or a health condition.

Microcytic anemia definition

Microcytosis is a term used to describe red blood cells that are smaller than normal. Anemia is when you have low numbers of properly functioning red blood cells in your body.

In microcytic anemias, your body has fewer red blood cells than normal. The red blood cells it does have are also too small. Several different types of anemias can be described as microcytic.

Microcytic anemias are caused by conditions that prevent your body from producing enough hemoglobin. Hemoglobin is a component of your blood. It helps transport oxygen to your tissues and gives your red blood cells their red color.

Iron deficiency causes most microcytic anemias. Your body needs iron to produce hemoglobin. But other conditions can cause microcytic anemias, too. To treat a microcytic anemia, your doctor will first diagnose the underlying cause.

You may not notice any symptoms of microcytic anemia at first. Symptoms often appear at an advanced stage when the lack of normal red blood cells is affecting your tissues.

Common symptoms of microcytic anemias include:

  • fatigue, weakness, and tiredness
  • loss of stamina
  • shortness of breath
  • dizziness
  • pale skin

If you experience any of these symptoms and they don’t resolve within two weeks, make an appointment to see your doctor.

You should make an appointment to see your doctor as soon as possible if you experience severe dizziness or shortness of breath.

Microcytic anemias can be further described according to the amount of hemoglobin in the red blood cells. They can be either hypochromic, normochromic, or hyperchromic:

1. Hypochromic microcytic anemias

Hypochromic means that the red blood cells have less hemoglobin than normal. Low levels of hemoglobin in your red blood cells leads to appear paler in color. In microcytic hypochromic anemia, your body has low levels of red blood cells that are both smaller and paler than normal.

Most microcytic anemias are hypochromic. Hypochromic microcytic anemias include:

Iron deficiency anemia: The most common cause of microcytic anemia is an iron deficiency in the blood. Iron deficiency anemia can be caused by:

  • inadequate iron intake, usually as a result of your diet
  • being unable to absorb iron due to conditions like celiac disease or Helicobacter pylori infection
  • chronic blood loss due to frequent or heavy periods in women or by gastrointestinal (GI) bleeds from upper GI ulcers or inflammatory bowel disease
  • pregnancy

Thalassemia: Thalassemia is a type of anemia that’s caused by an inherited abnormality. It involves mutations in the genes needed for normal hemoglobin production.

Sideroblastic anemia: Sideroblastic anemia can be inherited due to gene mutations (congenital). It can also be caused by a condition acquired later in life that impedes your body’s ability to integrate iron into one of the components needed to make hemoglobin. This results in a buildup of iron in your red blood cells.

Congenital sideroblastic anemia is usually microcytic and hypochromic.

2. Normochromic microcytic anemias

Normochromic means that your red blood cells have a normal amount of hemoglobin, and the hue of red is not too pale or deep in color. An example of a normochromic microcytic anemia is:

Anemia of inflammation and chronic disease: Anemia due to these conditions is usually normochromic and normocytic (red blood cells are normal in size). Normochromic microcytic anemia may be seen in people with:

  • infectious diseases, such as tuberculosis, HIV/AIDS, or endocarditis
  • inflammatory diseases, such as rheumatoid arthritis, Crohn’s disease, or diabetes mellitus
  • kidney disease
  • cancer

These conditions can prevent red blood cells from functioning normally. This can lead to decreased iron absorption or utilization.

3. Hyperchromic microcytic anemias

Hyperchromic means that the red blood cells have more hemoglobin than normal. High levels of hemoglobin in your red blood cells makes them a deeper hue of red than normal.

Congenital spherocytic anemia: Hyperchromic microcytic anemias are rare. They may be caused by a genetic condition known as congenital spherocytic anemia. This is also called hereditary spherocytosis.

In this disorder, the membrane of your red blood cells doesn’t form correctly. This causes them to be rigid and improperly spherical shaped. They are sent to be broken down and die in the spleen because they don’t travel in the blood cells properly.

4. Other causes of microcytic anemia

Other causes of microcytic anemia include:

  • lead toxicity
  • copper deficiency
  • zinc excess, which causes copper deficiency
  • alcohol use
  • drug use

Microcytic anemias are often first spotted after your doctor has ordered a blood test known as a complete blood count (CBC) for another reason. If your CBC indicates that you have anemia, your doctor will order another test known as a peripheral blood smear.

This test can help spot early microcytic or macrocytic changes to your red blood cells. Hypochromia, normochromia, or hyperchromia can also be seen with the peripheral blood smear test.

Your primary care doctor may refer you to a hematologist. A hematologist is a specialist who works with blood disorders. They may be able to best diagnose and treat the specific type of microcytic anemia and identify its underlying cause.

Once a doctor has diagnosed you with microcytic anemia, they will run tests to determine the cause of the condition. They may run blood tests to check for celiac disease. They may test your blood and stool for H. pylori bacterial infection.

Your doctor might ask you about other symptoms you’ve experienced if they suspect that chronic blood loss is the cause of your microcytic anemia. They may refer you to a gastroenterologist if you have stomach or other abdominal pain. A gastroenterologist might run imaging tests to look for different conditions. These tests include:

  • abdominal ultrasound
  • upper GI endoscopy (EGD)
  • CT scan of the abdomen

For women with pelvic pain and heavy periods, a gynecologist may look for uterine fibroids or other conditions that could cause heavier flows.

Treatment for microcytic anemia focuses on treating the underlying cause of the condition.

Your doctor may recommend that you take iron and vitamin C supplements. The iron will help treat the anemia while the vitamin C will help increase your body’s ability to absorb the iron.

Your doctor will focus on diagnosing and treating the cause of the blood loss if acute or chronic blood loss is causing or contributing to microcytic anemia. Women with iron deficiency from severe periods may be prescribed hormonal therapy, such as birth control pills.

In cases of microcytic anemia so severe that you’re at risk for complications like cardiac failure, you may need to get a blood transfusion of donor red blood cells. This can increase the number of healthy red blood cells that your organs need.

Treatment can be relatively straightforward if simple nutrient deficiencies are the cause of microcytic anemia. As long as the underlying cause of the anemia can be treated, the anemia itself can be treated and even cured.

In very severe cases, untreated microcytic anemia can become dangerous. It can cause tissue hypoxia. This is when the tissue is deprived of oxygen. It can cause complications including:

  • low blood pressure, also called hypotension
  • coronary artery problems
  • pulmonary problems
  • shock

These complications are more common in older adults who already have pulmonary or cardiovascular diseases.

The best way to prevent microcytic anemia is to get enough iron in your diet. Increasing your vitamin C intake can also help your body absorb more iron.

You can also consider taking a daily iron supplement. These are often recommended if you already have anemia. You should always talk to your doctor before you start taking any supplements.

You can also try to get more nutrients through your food.

Foods rich in iron include:

  • red meat like beef
  • poultry
  • dark leafy greens
  • beans
  • dried fruits like raisins and apricots

Foods rich in vitamin C include:

  • citrus fruits, especially oranges and grapefruits
  • kale
  • red peppers
  • Brussels sprouts
  • strawberries
  • broccoli

Erythrocyte indices – what is a color index

Erythrocytes

Erythrocytes (red blood cells) – blood cells that carry oxygen from the lungs to tissues and organs, and transport carbon dioxide back.

Normally, erythrocytes look like discs, concave on both sides. Due to this shape, they are more elastic and penetrate even the narrowest vessels.

Unlike most other cells, erythrocytes do not have a nucleus: 98% of their volume is occupied by hemoglobin is a protein that binds oxygen.

In one day, the red blood cells of an adult carry about 800 liters of oxygen and 200 liters of carbon dioxide.

In addition, these cells are involved in the transport of nutrients and help maintain acid-base balance.

In the form of a blood test, erythrocytes are designated by the Latin letters RBC – red blood cells (red blood cells).

What are erythrocyte indices

Red blood cell indices are indicators that measure the size of red blood cells and their hemoglobin content. Indices are considered fairly stable parameters, since they characterize not the number of erythrocytes, but their physiological properties.

Color value

Color indicator reflects the degree of saturation of the erythrocyte with hemoglobin: the more hemoglobin, the more red the erythrocyte will be.

Normal: 0.85 – 1.00. The indicator is measured in calculation units.
If the color index is above the norm, it is considered hyperchromic. The color index is below normal – hypochromic.

Main causes of hyperchromia

Pernicious anemia (megaloblastic, B12-deficient) is a pathology in which the maturation of red blood cells in the bone marrow is impaired due to poor absorption of vitamin B12.

Folate deficiency anemia is a disorder of hematopoiesis in the bone marrow associated with folic acid deficiency. The disease is often diagnosed together with iron deficiency anemia. It is especially dangerous for pregnant women, as it can lead to impaired development of the fetal nervous system.

Myelodysplastic syndrome is an oncological disease in which the normal maturation of all blood cells in the bone marrow is disturbed. Risk factors for the development of the disease: radiation therapy, chemotherapy, smoking, exposure to heavy metals (mercury, lead).

Main causes of hypochromia

Posthemorrhagic anemia is a condition associated with acute or chronic blood loss. The main symptoms are: pallor, shortness of breath, darkening of the eyes, and in severe cases – lethargy, thready pulse, loss of consciousness.

Acute posthemorrhagic anemia is associated with rapid massive blood loss in trauma, surgery, gastric and duodenal ulcers, ectopic pregnancy. Chronic – due to frequent loss of a small amount of blood. This happens with gastrointestinal, nasal, uterine bleeding, as well as with diseases associated with impaired blood clotting.

Frequent nosebleeds can lead to chronic posthemorrhagic anemia

Iron deficiency anemia is a condition in which there is not enough iron in the body, which is necessary for the normal synthesis of hemoglobin. Most often, such anemia develops due to chronic blood loss or impaired iron intake. In addition, iron deficiency anemia occurs in people with increased iron consumption: women of reproductive age (due to monthly blood loss during menstruation), pregnant women, as well as children and adolescents (due to intensive body growth).

Anemia associated with lead toxicity is a condition commonly found in industrial workers. Lead is a heavy toxic metal. It blocks the enzymes necessary for the synthesis of hemoglobin. As a result, the hemoglobin content in the erythrocyte decreases.

Deviation towards hyperchromia (oversaturation with hemoglobin) is often combined with an increase in the size of red blood cells. This condition is called macrocytosis or megalocytosis. Conversely, with hypochromia (lack of hemoglobin), the size of red blood cells is usually lower: this is microcytosis.

Recently, instead of studying the color index, the determination of MCH is increasingly used – the average hemoglobin content in the erythrocyte.

Mean erythrocyte hemoglobin (MCH)

The mean concentration of hemoglobin in one erythrocyte (MCH) shows the mass of iron-containing protein in one red cell. Measured in picograms (pg): 1 pg is one trillionth of a gram.

The indicator depends on the gender and age of the patient. The highest values ​​are observed in newborns under the age of 14 days. Then, as they grow older, MCH gradually decreases and equalizes with the norm for adults.

Hemoglobinopathy is a hereditary pathology associated with a violation of the structure of hemoglobin.

Thalassemia is a special case of hemoglobinopathy, a hereditary disease in which the chemical structure of hemoglobin is disturbed due to the pathology of the synthesis of proteins that make up its composition.

Main reasons for increasing MCH

Pernicious anemia (megaloblastic, B12 deficiency) is a condition in which the maturation of red blood cells in the bone marrow is impaired due to vitamin B12 deficiency. With such anemia, the number of red blood cells in the blood decreases, and there is a lack of oxygen in the tissues.

Hemolytic anemia – a condition in which there is an increased destruction of red blood cells and the breakdown of hemoglobin, which is part of them.

Folate deficiency anemia – a violation of the formation of red blood cells in the bone marrow, caused by a deficiency of folic acid. This condition can occur against the background of insufficient intake of folic acid from food, malabsorption of folic acid in diseases of the gastrointestinal tract, liver diseases (especially viral hepatitis and cirrhosis), as well as malignant neoplasms and long-term use of certain drugs (anticonvulsants, cytostatics, some antibiotics). and etc.).

Mean erythrocyte hemoglobin concentration (MCHC)

Mean corpuscular hemoglobin concentration (MCHC) reflects the hemoglobin filling density of the red blood cell, measured in grams per liter (g/l).

Like the previous indicator, MCHC depends on the age of the patient. The highest values ​​are in newborns, then they gradually decrease to the norm for adults.

In adults (men and women), normal MCHC values ​​are independent of age and range from 300-380 g/l.

The reasons for the lower and higher MCHC index are the same as for the previous indicator, MCH.

Mean erythrocyte volume (MCV)

Erythrocyte index MCV (mean cell volume) characterizes the size of red blood cells contained in the blood. The indicator is measured in femtoliters (fl).

A femtoliter is a unit of volume equal to one cubic micrometer (one millionth of a metre).

If the erythrocytes are too large in size, then it is difficult for them to pass through the small capillaries. If they are too small, they cannot carry enough oxygen. In both cases, the risk of hypoxia, i.e. oxygen starvation of tissues, increases significantly.

Reducing the size of red blood cells is called microcytosis.

Main causes of microcytosis

Iron deficiency anemia is a condition in which there is not enough iron in the body, which is necessary for the normal synthesis of hemoglobin.

Hereditary anemias are hereditary diseases in which the synthesis of red blood cells is impaired, and their life span is significantly less than that of normal red blood cells.

Hemoglobinopathy is a congenital pathology in which the structure of the hemoglobin protein is disturbed and it can no longer transport oxygen normally from the lungs to the tissues.

Main causes of macrocytosis

Pernicious anemia (megaloblastic, B12-deficient) is a violation of the formation of red blood cells in the bone marrow, provoked by vitamin B12 deficiency.

Folate deficiency anemia is a violation of the synthesis of red blood cells associated with a lack of folic acid. This condition can be caused by liver diseases (hepatitis, cirrhosis), oncological diseases, long-term use of drugs, such as anticonvulsants, cytostatics, certain antibiotics, etc.

RBC heterogeneity index by volume (RDW)

The RDW (red cell distribution width) index of erythrocyte heterogeneity by volume shows how erythrocytes differ from each other in size. The indicator is measured as a percentage.

In children under the age of 6 months, the normal value of RDW is 14.9-18.7%. In children older than 6 months, adolescents and adults – 11.6–14.8%.

A decrease in the RDW index has no clinical significance. And an increase, as a rule, is observed at iron deficiency anemia – a pathological condition in which the synthesis of red blood cells and hemoglobin is impaired due to a lack of iron in the body.

Erythrocyte indices: indications for testing

The study of erythrocyte indices is included in the general blood test, which is prescribed in a planned manner: during the annual preventive examination, as well as when anemia is suspected. The test is repeated for patients who are being treated for anemia.

Diagnosis of causes of anemia

If anemia is detected by the deviation of erythrocyte indices from the norm, it is necessary to establish the cause of its development. To do this, the therapist can prescribe additional tests or refer the patient to another doctor, for example hematologist – a specialist in the treatment of diseases of the blood and blood-forming organs.

Iron deficiency anemia

If iron deficiency anemia is suspected, it is advisable to investigate the indicators of iron metabolism: ferritin, transferrin, total serum iron-binding capacity (TIBC), serum iron level and transferrin iron saturation coefficient.

Find out what white blood cells, red blood cells, ESR and hemoglobin mean in a blood test. Find out what values ​​\u200b\u200bmay indicate the presence of diseases or disorders in the body.

A blood test is one of the most common diagnostic methods that provides information about the state of the patient’s body. A blood test includes the study of parameters such as the number of leukocytes, red blood cells, hemoglobin and ESR.

Leukocytes are white blood cells that perform a protective function in the body. The number of white blood cells in the blood can vary depending on various factors such as infection, inflammation, stress, and others. Therefore, the analysis of the level of leukocytes helps to assess the presence of inflammatory processes and infections in the body.

Erythrocytes are red blood cells that contain hemoglobin. Hemoglobin, in turn, allows the blood to transport oxygen and carbon dioxide. A change in the number of red blood cells may indicate various blood diseases, for example, the manifestation of anemia.

ESR (erythrocyte sedimentation rate) is an indicator that displays how quickly red blood cells settle in the blood plasma. A change in the erythrocyte sedimentation rate may indicate the presence of inflammatory, infectious or other diseases.

Hemoglobin is a protein found in red blood cells. It transfers oxygen in the body and protects against oxygen starvation. Analysis of hemoglobin levels allows you to assess the presence or absence of various diseases, such as anemia or other pathological conditions.

Blood test: indicators and value

Leukocytes

The level of leukocytes in the blood is an important indicator of human health. Leukocytes are white blood cells that are responsible for protecting the body from infection and disease. The normal level of white blood cells in the blood ranges from 4 to 10 thousand per microliter. An elevated level of white blood cells may indicate the presence of an infectious disease in the body, and a low level may indicate an immunodeficiency state.

Red blood cells and hemoglobin

Red blood cells are red blood cells that carry oxygen through the bloodstream. The normal level of red blood cells in the blood is 4.5 to 5.5 million per microliter in men and 4 to 5 million per microliter in women. Hemoglobin is a protein found in red blood cells that binds oxygen and carbon dioxide. The normal hemoglobin level in men is 130 to 160 grams per liter, and in women it is 120 to 140 grams per liter. Low levels of red blood cells and hemoglobin can indicate iron deficiency anemia, injury, blood loss, and elevated levels of hemoglobin can indicate respiratory diseases and other diseases.

ESR

ESR (erythrocyte sedimentation rate) is an indicator that characterizes the rate of erythrocyte sedimentation in a flask over a certain period of time. The normal level of ESR in women is from 2 to 15 mm/hour, and in men – from 1 to 10 mm/hour. Elevated levels of ESR may indicate the presence of inflammatory processes and infections in the body.

Leukocytes: their role in blood tests

Leukocytes are white blood cells that protect the body from infections and diseases. Their amount in the blood characterizes the patient’s immune system and may indicate the presence of a disease.

A blood test for leukocytes includes determining their total number and percentage of different types of leukocytes. The total white blood cell count may vary depending on various factors such as physical exertion, stress, infections, etc.

  • Neutrophils are the most numerous type of leukocyte responsible for fighting bacterial infections.
  • Lymphocytes are the main cells of the immune system responsible for defense against viruses and other pathogens.
  • Monocytes are phagocytic cells capable of removing dead and damaged cells from the blood.

Changes in white blood cell count can indicate inflammation, infections, allergies, or even cancer. If anomalies are detected as a result of the analysis, it is recommended to consult a doctor for consultation and additional examinations.

Red blood cells: functions and significance in the blood test

Red blood cells, also known as red blood cells, play a key role in the functioning of the body. They contain hemoglobin, a protein component that is responsible for transporting oxygen from the lungs to the tissues. Red blood cells also play an important role in removing carbon dioxide from tissues and transporting it back to the lungs for excretion from the body.

Red blood cells are usually measured in millions of cells per microliter of blood (µl). The normal level for men is 4.3 to 5.7 million/mcL, for women it is 3.8 to 5.1 million/mcL. A low red blood cell count can indicate various conditions, such as anemia, blood loss or blood loss, as well as the presence of certain diseases, including leukemia and leukemia.

  1. Causes of an increase in the level of red blood cells:
  2. Physical activity;
  3. Lack of oxygen in the body;
  4. Possible illnesses such as lung or cardiovascular disease;
  5. Certain hereditary diseases;
  • Causes of low red blood cells:
  • Anemia;
  • Blood loss or blood loss;
  • Certain diseases such as leukemia, leukemia and bone marrow diseases;
  • Metabolic disorders;

Observing the level of red blood cells as a result of a blood test is an extremely important indicator of the health of the body. It allows you to identify the presence of anomalies and diseases, as well as to determine their degree and nature of development. With an increase or decrease in the level of red blood cells, you should consult a specialist and undergo additional studies to determine the causes and prescribe the correct treatment.

ESR

Erythrocyte sedimentation rate (ESR) is a measure that measures the rate of erythrocyte sedimentation in a test tube. This indicator is an important element in the general blood test.

ESR may be elevated in patients with infectious diseases, autoimmune diseases, cancer, and other inflammatory diseases.

  • Normal ESR in men: 0 to 15 mm/hour.
  • Normal ESR in women: 0 to 20 mm/h.

Norm ESR, mm/hour Women Men

Up to 50 years 0-20 0-15
Over 50 years 0-30 0-20

At elevated levels of ESR, it is necessary to conduct additional studies and find out the reason for this increase.

Hemoglobin

Hemoglobin is the protein component of red blood cells (erythrocytes) that is responsible for transporting oxygen from the lungs to tissues and back. Hemoglobin is composed of four subunits, each containing a heme group that binds oxygen and transports it through the blood. Hemoglobin is measured in grams per deciliter of blood (g/dL) and gives an indication of the amount of oxygen the blood can carry.

The normal level of hemoglobin depends on the age and sex of the person. In healthy men, hemoglobin levels range from 13.5 to 17.5 g/dL, and in healthy women, from 12.0 to 15.5 g/dL.

Low hemoglobin (anemia) can occur due to a variety of reasons, including iron deficiency, vitamin B12 deficiency, folic acid deficiency, blood loss, genetic disorders and other diseases. Symptoms of anemia can include lethargy, weakness, dizziness, palpitations, and shortness of breath.

  • To maintain a normal level of hemoglobin in the blood, it is necessary: ​​
  • – Eat iron-rich foods such as red meat, animal organs, legumes, green vegetables and dried fruits.
  • – Drink enough fluids to reduce the viscosity of the blood and facilitate its circulation.
  • – Avoid smoking and excessive alcohol consumption, which can reduce the amount of oxygen available in the blood.

High hemoglobin , also known as erythrocytosis, may be associated with smoking, altitude, polycythemia (an increased number of red blood cells), and other medical conditions.

Hemoglobin (g/dL) Interpretation

Less than 12.0 Low hemoglobin Normal hemoglobin level
13.5 — 17.5 (men) Normal hemoglobin level
More than 17.5 High hemoglobin

Normal values ​​

A blood test includes several parameters that help determine the overall health of the body. The normative values ​​for each parameter usually differ depending on age, gender and other factors.

Leukocytes

The normal level of leukocytes in the blood varies from 4,000 to 10,000 per cubic millimeter. This indicator displays the number of white blood cells that protect the body from infections and diseases. It can increase with inflammation and infectious diseases.

Red blood cells

The level of red blood cells, or red blood cells, also varies with age and sex. Typically, the level of red blood cells in the blood ranges from 4 to 6 million per cubic micrometer in men and from 3.5 to 5.5 million per cubic micrometer in women. This parameter displays the ability of blood to carry oxygen from the lungs to tissues and organs.

ESR

Erythrocyte sedimentation rate, or ESR, is an indicator of inflammation and disease in the body. The normal level of ESR in women is from 0 to 20 mm / h, in men – from 0 to 15 mm / h. However, ESR levels may be elevated in a number of conditions, including infections, autoimmune diseases, and cancers.

Hemoglobin

The hemoglobin level reflects the amount of oxygen carried by the blood. The normal hemoglobin level in men is 13. 5 to 17.5 g/dl and in women it is 12.0 to 15.5 g/dl. This setting can be changed for various diseases including anemia, cardiovascular disease and various blood disorders.

How is the blood test for leukocytes, erythrocytes, soy and hemoglobin?

Blood sampling

A blood test for leukocytes, erythrocytes, ss and hemoglobin is carried out after taking blood from a vein. For this, a special needle is used, which is used to puncture the skin in the area of ​​\u200b\u200bthe elbow.

After the needle enters the vein, blood with a sterile syringe tube is collected in several samples: each sample is reserved for a certain type of research.

Preparation for analysis

It is recommended to abstain from food for 8-12 hours before testing for leukocytes, erythrocytes, soy and hemoglobin. For the accuracy of the result, it is also important not to smoke or exercise for several hours before taking blood.

It is also important to inform the lab analyzer of all medications you are taking, as some of them may skew the blood test results.

Analysis processing

Blood collected for analysis is sent to a special laboratory. They conduct various studies, which may include counting leukocytes and erythrocytes, measuring hemoglobin and soy.

WBC, RBC, ESR and hemoglobin results are usually available in a few days.

When should I take a blood test for leukocytes, erythrocytes, soy and hemoglobin?

The need for a blood test is due to several factors, including:

  • preventive medical examinations;
  • onset of disease symptoms;
  • disease control;
  • confirmation of diagnosis;
  • prescribing drugs and monitoring their effectiveness;
  • assessment of the functioning of the organism.

WBC, RBC, ESR, and hemoglobin blood tests may be ordered by a physician as part of a preventive health check-up, which is recommended annually. Also, an analysis can be prescribed if the patient has certain symptoms of the disease, such as fever, headache, weakness, anemia, bleeding, and others.

Blood tests for leukocytes, erythrocytes, ESR and hemoglobin are necessary for certain types of medical interventions, such as surgery, childbirth and others. When prescribing drugs, it is also necessary to monitor their effectiveness and observe the correct dosage.

Effect of diet on blood test results

Blood test is an important way to monitor the state of the body. Leukocytes, erythrocytes, soy and hemoglobin – all these indicators reflect the main functions of the blood. However, few people know that nutrition can also affect them.

However, there are certain foods that can improve blood test results. For example, eating iron-rich foods in moderation can help restore hemoglobin levels. At the same time, an excess of such products can also adversely affect the condition of the blood.

  • Recommendations:
  • When changing diet, be sure to pay attention to the blood test results.
  • You should not strive for too strict diets, which can lead to a deficiency of useful elements in the body.
  • You can include iron-rich foods in your diet by simply controlling their amount.

Interpreting blood test results

White blood cells

White blood cells (leukocytes) are an important part of the immune system that can protect the body from infections and other diseases. An elevated white blood cell count may indicate an infection or inflammation in the body. A decrease in the level of leukocytes may indicate a decrease in immunity or problems in the bone marrow.

Red blood cells

Red blood cells (erythrocytes) carry oxygen throughout the body. A low red blood cell count can indicate anemia, which can be caused by a variety of causes, including iron deficiency anemia, vitamin deficiencies, and other medical conditions. High red blood cell levels may indicate cardiovascular problems such as polycythemia and hypoxia.

ESR

The erythrocyte sedimentation rate (ESR) is an indicator that reflects the rate of red blood cell sedimentation in the blood. This indicator can be increased in diseases such as rheumatoid arthritis, inflammatory bowel disease and others. However, elevated ESR may also be related to age and other normal factors.

Hemoglobin

Hemoglobin is the protein component of red blood cells that is responsible for transporting oxygen in the body. Low hemoglobin levels can indicate anemia and other conditions. A high level of hemoglobin can indicate problems with the cardiovascular system, such as polycythemia, chronic obstructive pulmonary disease, and others.

Additional tests

Urinalysis

If there are abnormalities in the blood counts of leukocytes, erythrocytes, ESR and hemoglobin, it is necessary to conduct an additional study – urinalysis. This analysis allows you to detect the presence of infectious processes in the urinary tract, determine the level of proteins and glucose in the urine, and also detect the presence of blood, which may indicate the presence of diseases of the kidneys and bladder.

Biochemical blood test

Additionally, a biochemical blood test is performed, which allows you to determine the level of hormones, proteins, lipids, carbohydrates, minerals, etc. As a result of this analysis, you can detect the presence of diseases of the liver, kidneys, diabetes, metabolic disorders, etc.

Bone marrow biopsy

If leukemia or other blood disorders are suspected, a bone marrow biopsy is performed. During the study, a small sample of bone marrow tissue is taken, which is examined for the presence of malignant cells and other abnormalities.

  • Additional examinations provide a complete picture of the state of health.
  • Some diseases can only be detected with additional tests.
  • After receiving the results of tests and studies, the doctor prescribes the correct treatment and recommendations for the patient.
