Blood is taken for analysis in order to determine the state of the body and its functionality, identify organ diseases, hormonal imbalances, lack of vitamins and nutrients, find out about the presence of viruses and infections, inflammatory processes and other diseases. Blood is also taken to monitor the progress of pregnancy and to identify its group and Rh factor.

Types of blood tests

There are 5 main types of blood tests:

  1. General clinical blood test
    , which is carried out as part of a general clinical examination of the patient. Allows you to assess your overall health and identify a number of problems that will require further diagnosis.
  2. A biochemical blood test
    allows you to analyze the functioning of internal organs, metabolism, metabolism and the body’s need for trace elements and vitamins;
  3. Immunological blood test
    - detects viral, infectious, oncological and allergic diseases;
  4. A hormonal blood test
    allows you to determine the level of hormones and draw conclusions about the correct functioning of the thyroid gland, pituitary gland, adrenal glands, genital organs and others.
  5. A serological blood test
    shows the stage of the infectious process.

Each test examines a number of blood parameters in a laboratory setting. Depending on the purpose of the study, the maximum number of parameters or a small part that is important for identifying violations is studied. Based on the results of the analysis, the patient receives a table with blood parameters and their values, which are then deciphered by the doctor, prescribe additional tests and make a diagnosis.

In addition, there are other tests, for example, blood type and Rh factor. This information is important for serious illnesses such as blood transfusions and organ transplants.

Functions of monocytes

When aggressive substances or microorganisms enter the surface of the mucous membrane of the nasopharynx or intestine, histiocytes flock to the lesion. These are “ripe” monocytes, adapted to life in tissues. If necessary, new portions of histiocytes-macrophages are urgently prepared.

They surround bacteria, viruses, fungi, and foreign particles, draw them into the protoplasm and provide work to lysosomes to completely dissolve unnecessary molecules.

Having cleared the “battlefield” of toxins and decayed leukocytes, macrophages move on to the process of transmitting information to subsequent generations. This ensures quick recognition of “friends” and “strangers” and aims the body at defense.

Unlike eosinophils, neutrophils, and lymphocytes, cells of the monocyte series are able to “fight” large species of the “enemy” and do not die immediately after the “attack.” Can be reused.

General clinical blood test

It is carried out as part of a general clinical examination of the patient and allows you to learn about the condition of the blood and the body as a whole. The main indicators of this analysis are: hemoglobin, the number of leukocytes (white blood cells), erythrocytes (red blood cells) and platelets (nuclear-free plates of blood responsible for clotting).

Due date and how to prepare

A general blood test is taken in the morning on an empty stomach, often from a finger, less often from a vein. You should not drink or eat 4 hours before the test.

Metrics collected

Now a general blood test is carried out on automatic hematological analyzers, which can simultaneously determine values ​​from 5 to 24 parameters.

The main indicators collected are:

  1. Hemoglobin (HGB - hemoglobin)
    - the main component that is involved in the transfer of oxygen in the blood from the lungs to organs and tissues, and carbon dioxide back to the lungs, is the blood pigment of red blood cells.
  2. Red blood cells (RBC - red blood cells)
    are red blood cells that carry oxygen in the blood to organs and tissues.
  3. Leukocytes (WBC - white blood cells)
    are white blood cells produced in the bone marrow that carry out immune control and protect the body from foreign cells.
  4. Thrombocytes (PLT - platelets)
    are nuclear-free platelets of blood responsible for clotting.
  5. Lymphocytes (LYM - lymphocyte)
    are cells of the immune system that respond to viruses and microbes.
  6. Monocytes (MON - monocyte)
    are large cells of the immune system.
  7. Hematocrit (HCT - hematocrit)
    is the volume of red blood cells in the blood.
  8. Blood color index (BI)
    , demonstrating the concentration of hemoglobin in red blood cells.
  9. Erythrocyte sedimentation rate
    , which, if deviated from the norm, may indicate a pathological condition of the body.
  10. Various erythrocyte, leukocyte and platelet indices
    .

Symptoms of increase and decrease

An increase in the level of phagocytes is almost always associated with a pre-existing disease of the internal organs or soft tissues.

In this case, the woman experiences the following symptoms:

  • increased body temperature, which can range from 37 to 40 degrees Celsius;
  • severe headache, chills, fever;
  • epigastric pain, possible nausea and vomiting;
  • shortness of breath, feeling of lack of air and rapid heartbeat;

  • frequent urge to urinate;
  • complete or partial loss of appetite;
  • possible intestinal dysfunction, which is expressed in attacks of liquid diarrhea (this symptom manifests itself if there has been an infectious invasion of the gastrointestinal tract);
  • red rash, hives, swelling that appears on various parts of the body, and is also accompanied by severe itching;
  • inflammation of the oral mucosa, swelling of the tonsils, gingivitis.

Signs of increased monocyte levels may be expressed in other pathological conditions of the body. It all depends on what disease provoked a sharp surge in the phagocytic activity of the immune system.

A decrease in monocyte concentration is most often manifested by the following symptoms:

  • the body’s tendency to frequent colds, infectious, viral and fungal diseases;
  • feeling of constant fatigue;
  • decreased ability to work;
  • drowsiness;
  • ulcerative lesions of the skin surface and the development of various types of dermatitis;
  • changes in the biochemical composition of blood;
  • dyspnea;
  • tachycardia, as well as other signs of disturbances in the rhythmic activity of the heart.

As in the case of an increase in the level of monocytes, a decrease in their concentration also indicates the presence of an acute or chronic disease of the body, or is a consequence of heavy blood loss.

When to take it

A biochemical blood test must be taken:

  1. As prescribed by a doctor;
  2. As part of routine medical examinations and examinations;
  3. To assess the functioning of internal organs and the functionality of the body;
  4. To determine the need for microelements;
  5. For information about metabolism;
  6. After suffering from infectious or somatic diseases.

Biological role in the body

The biological role of monocytes is very diverse. The largest phagocytes are necessary for many functions:

  1. Phagocytosis.

    During this process, monocytes and macrophages identify proteins, bacteria, and viruses that are dangerous to the body, capture them and absorb them (phagocytose).

  2. Participation in the development of specific immunity.

    Monocytes produce special cytotoxins, interferon, to counteract pathogenic viruses, bacteria and fungi.

  3. Assistance in the formation of allergic reactions.

    Thanks to monocytes, specific elements of the compliment system are produced. Due to these processes, foreign proteins - allergens - are identified.

  4. Protection against tumors.

    It is carried out through the production of tumor necrosis factor.

  5. Regulation of hematopoiesis and blood clotting processes

    - carried out through the synthesis of specific elements.

Monocytes have special characteristics that distinguish them from neutrophils and other phagocytes:

  • After absorbing a foreign element, monocytes do not die, but continue to function actively. In rare cases, the pathogen can defeat them.
  • The life cycle of monocytes is longer than that of neutrophils.
  • Monocytes have a pronounced antiviral effect, neutrophils have an antibacterial effect.
  • When many monocytes are activated against a foreign agent, pus does not form.
  • Chronic inflammatory process is a favorite place for concentration of macrophages and monocytes

Immunological blood test

A laboratory blood test that examines blood serum obtained by centrifugation. The presence and level of antibodies are detected in the serum to determine infectious diseases, allergies, parasitic infestations, autoimmune diseases, immunodeficiency states of the body and neoplasms. An immunological blood test detects infections such as syphilis, chlamydia, mycoplasma, ureaplasma, trichomonas, gonorrhea, herpes, HIV, AIDS, measles, hepatitis, cytomegalovirus, mumps, toxoplasmosis, rubella, coronaviruses, COVID-19 and many others.

Due date and how to prepare

An immunological blood test is taken in the morning on an empty stomach from a vein. You should not eat 12 hours before the test. Avoid alcoholic drinks for 3 days. Avoid solariums and x-rays for 2 days. Don't stress in 1 day. No smoking for 1 hour. You should not do the test during menstruation.

Metrics collected

General indicators of immunological blood test:

  1. Subpopulations of lymphocytes
    are different types of white blood cells that recognize various foreign structures, altered body cells and produce antibodies to destroy them. The indicators of this group give a general idea of ​​the state of immunity.
  2. Immunoglobulins
    - various types of antibodies, the purpose of which is to destroy infections and toxins. The presence of certain antibodies in the blood indicates the infections they are fighting against. Main types of immunoglobulins:
      A (IgA)
      - responsible for the immunity of mucous membranes;
  3. M (IgM)
    - responsible for the body’s primary defense reaction;
  4. G (IgG)
    - responsible for the main fight against infections that have entered the body;
  5. E (IgE)
    and
    D (IgD)
    - responsible for the fight against parasites and allergens.

Reasons for promotion and demotion

Monocytes (the norm for women by age, a table of clinical indicators is compiled based on the results of a diagnostic examination of the body) are blood cells that are part of the body’s immune system, and an increase in their concentration indicates the possible presence of the following diseases:

  • infection of the digestive system by helminths;
  • invasion of bacterial, viral and fungal microorganisms;
  • tuberculosis of the lymphatic system or lung tissue;
  • typhoid fever;
  • all types of sexually transmitted diseases (the most dramatic surge in monocyte activity is observed in the case of infection with syphilis);
  • brucellosis;
  • lymphomas of malignant etiology;
  • monocytic leukemia of a specific type;
  • blood damage by the malaria pathogen;
  • all types of malignant neoplasms that are localized in any part of the body;
  • herpesvirus infection, which was in a chronic form, and then moved to the acute stage;
  • endocarditis and rheumatoid tissue destruction;

  • skin damage associated with the parasitic activity of infectious microorganisms, acute allergic reaction or mechanical trauma.

During menstruation, most women allow a slight increase in the level of monocytes, which returns to normal 2-3 days after the end of menstruation. Such a reaction of the body is not a pathology.

A decrease in the concentration of phagocytes can be caused by the following reasons:

  • internal bleeding;
  • postoperative period of tissue restoration;
  • severe traumatic brain injury;
  • malignant neoplasms in the bone marrow;
  • long-term therapy with Prednisolone, cytotoxic drugs, as well as immunosuppressants;
  • state of shock;
  • prolonged stay in conditions of psycho-emotional overstrain and stress;
  • postpartum period;
  • presence of aplastic anemia.

A decrease in the level of phagocytes is no less an alarming signal than an increase in their number. The reasons that caused the change in the cellular composition of the blood must be established in a biochemical laboratory.

Indications for the study

Monocytes (the norm for women by age, a table of clinical indicators is compiled based on the results of a diagnostic examination of the body) are large leukocytes that play a key role in the full functioning of the immune system.

Direct indications for testing the level of phagocytes are the presence of the following symptoms:

  • frequent and unfounded intestinal disorders;
  • increased body temperature without obvious signs of inflammation;
  • tachycardia and disturbance of the rhythmic activity of the heart;
  • dyspnea;
  • dizziness and physical weakness;
  • rapid fatigue after minor exertion;
  • infectious and inflammatory skin diseases;
  • chronic diseases of the nasopharynx, upper and lower respiratory tract;
  • an allergic reaction that occurs in acute or chronic form.

The need for an analysis for the level of phagocytes in the blood serum is determined by the attending physician, who performs the initial examination of the patient.

Serological blood test

A laboratory blood test that involves the interaction of antibodies and antigens. It is carried out to identify infectious diseases and the stage of the infectious process.

Due date and how to prepare

A hormonal blood test is taken in the morning on an empty stomach from a vein.

Serological blood test methods

  1. To confirm the diagnosis, an antigen corresponding to the suspected disease is added to the blood serum, and if there is a reaction, then there are antibodies to the disease and the patient is sick.
  2. To determine the type of infection, antibodies of the expected type are added to the serum, and if there is a reaction, then there is an infection in the blood that corresponds to the added antibodies.

What is the result of a serological blood test?

The analysis provides an answer to whether there is a suspected infection in the human body.

When to take it

  • when prescribed by a doctor;
  • if you suspect a certain infection;
  • to prescribe the correct treatment.

How and under what conditions is it produced?

Previously, hematologists believed that phagocytes of this type are formed in the reticuloendothelial system. Recent scientific research has shown that monocyte synthesis occurs in bone marrow tissue.

Mature leukocytes, which have the most powerful phagocytic properties, are released into the bloodstream. The cells mature over the next 5 days, and then they become part of the peripheral blood.

The process of monocyte synthesis is inhibited during the period of taking drugs from the glucocorticoid group, as well as if a person is under constant stress for a long time. In this regard, immunity decreases, and the human body becomes more susceptible to infection by infectious, viral and fungal microorganisms.

How to determine

The level of monocytes is determined by a laboratory blood test to determine the percentage of vital cells. Capillary and venous blood is suitable for diagnosis.

Simultaneously with the level of phagocytes, the concentration of leukocytes is identified. A comparative analysis of qualitative blood parameters makes it possible to establish the severity of the infectious and inflammatory process that progresses in the female body.
