Blood analysis of Kherson

In laboratory Diagnostics blood occupies an important place among other laboratory diagnostic procedures. Blood – This liquid fabric, which consists of plasma, erythrocyte, leukocytes and platelets. Plasma make up water (90%) and the dry residue (10%) -proteins, fats, carbohydrates, trace elements, Salt, hormones and other.

Blood performs important functions, such as:
  • transport-transport of oxygen and nutrients to organs and tissues;
  • gomeostatičeskaâ-maintenance of body temperature, acid-base state of the organism, water-salt Exchange, tissue homeostasis and tissue regeneration;
  • protective — immune reactions, blood and tissue barriers against infection;
  • regulatory-humoral and hormonal regulation of the functions of the various systems and tissues;
  • secretory cells of blood — education of biologically active substances.

Various changes (deviations from the norm) the composition of the blood are important diagnostic value at the beginning of developing disease.

Blood test is an essential tool for timely diagnosis of pathological conditions, monitoring of diseases, control of the treatment and diagnosis of preclinical stages of diseases when screening and prevention surveys.

The simplest, informative study of the blood is the blood test. This group studies include:

  • General blood analysis, used in screening and prophylactic medical examinations, When monitoring therapy, the differential diagnosis of diseases of the blood;
  • leukogram, that reflects the percentage of different types of leukocytes. Blood analysis in the study of Leukocyte formula is of great importance in the diagnosis of haematological, infectious, inflammatory diseases;
  • ESR is an important indicator in acute inflammatory and infectious processes in the body;
  • Reticulocyte-counting is set to assess the degree of activity of erythropoiesis (the development of anemia).

Among the main types of blood tests are described below.: biochemical, blood tests for hormones, allergens, onkomarkëry, determination of the immune status organism, diagnosis of infectious diseases.

Biochemical blood analysis aimed at identifying the level of glucose, proteins and amino acids, nitrogenous substances, pigments, lipid composition, enzymes, vitamins, proteins, inorganic substances, in t. h of trace elements. The blood test gives you the opportunity to identify violations of the liver and kidney, pathology of the cardiovascular system, the diagnosis of anemia, in the differential diagnosis of oncological diseases.

Timely analysis of blood hormones will help identify the hormonal changes, that may be a consequence of disruption of thyroid, pancreas and gonads; allows you to determine the dysfunction of lipid metabolism; assess the condition of the gastrointestinal tract.

Blood test for allergens is among a group of immunological studies, that gives an idea of the condition of the human immune system in General. The main objective of diagnosis in allergic diseases – identification of the allergen or allergens, to which there is increased sensitivity of the patient. In modern laboratory Diagnostics of blood test is widely used to identify the allergen, that caused an allergic reaction (food, household, the chemical compounds, the pollen of plants).

A blood test is an important technique in the diagnosis of infectious diseases (viral, bacterial, fungal, parasitic).

Blood test helps determine predisposition to various diseases while conducting genetic research (blood is one of the main methods of biological relationship).


General blood analysis is desirable on an empty stomach. Between the last meal and taking a blood sample should be at least 8 hours.

Results of the analysis

Hemoglobin (Hb, hemoglobin) Breathing blood pigment, involved in the transport of oxygen and carbon dioxide, performs a buffer function (maintenance of Ph). Contained in erythrocytes (blood red blood cells). Consists of protein parts – globin gene – and porfirinovoj-bearing parts – heme. It is a protein with Quaternary structure, the educated 4 and bound. Iron in bivalent form is a geme.

The physiological form of hemoglobin:
1) the oxyhaemoglobin around the body (HbO2) – connection of hemoglobin with oxygen is formed, predominantly, in arterial blood and gives her the Scarlet (oxygen binds to the iron Atom through the coordination of); 2) reconstituted hemoglobin or dezoksigemoglobin (HbH) – hemoglobin, who gave the oxygen the tissues; 3) carboxyhemoglobin (HbCO2) – connection of hemoglobin with carbon dioxide; is formed, predominantly, in venous blood, which is the Burgundy color.
Abnormal forms of hemoglobin:
1) karbgemoglobin (HbCO) – is formed when carbon monoxide poisoning (WITH), the hemoglobin is unable to attach oxygen; 2) methemoglobin – is formed under the influence of nitrite, nitrates and certain medications (the transition occurs, bivalent iron in trëhvalentnoe with the formation of methemoglobin – HbMet. Hemoglobin content in the blood of men slightly higher, than women. The children of the first year of life there is a physiological reduction in hemoglobin concentration. Decrease in hemoglobin in the blood (anemia) may be due to elevated haemoglobin loss during various kinds of bleeding or increased destruction (severe) erythrocyte. The cause of anemia iron deficiency can be, necessary for the synthesis of hemoglobin, or vitamins, involved in the formation of red blood cells (mostly B12, folic acid), as well as violation of blood cells with specific haematological diseases. Anemia may occur secondary to various chronic non-hematological diseases.
