majority who give tests do not know what shows the CBC, what are the basic rules of general analysis of blood, and that can mean changing them.

According to statistics, 90% of people do not know why they donate blood from a finger.But the knowledge that shows the complete blood count, can tell you about many diseases, since almost any pathology is reflected in the change of the composition of blood.Consider the basic indicators.

What does the CBC: basic indicators


It is a protein that transports oxygen from the lungs to cells throughout the body.

  • rate for males - 130-160 g / l
  • rate for women - 120-140 g / l

Reducing this figure is called anemia.There are several types of anemia, depending on the reasons that caused them.Raising hemoglobin levels may indicate certain diseases of the cardiovascular system, erythrocytosis and dehydration.


They contain hemoglobin.

  • rate for men - 4-5 million per 1 ml of blood
  • rate for women - 3,9-4,7 million per 1 ml of blood

decrease in the number of red blood cells occurs in anemia, as well as metastatic tumors and leukemia.The increase of this index can be in dehydration, insufficient function of the adrenal cortex, with some congenital heart defects.

color indicator

  • Norma - 0,85-1,05

expresses the amount of hemoglobin in a red blood cell.This indicator is important to determine the type of anemia.


This "young" erythrocytes.

  • norm - 2-10%

OVER standards observed in malaria, anemia, an increase in the number of red blood cells.Reducing the number of reticulocytes speaks about the poor performance of the bone marrow.

Platelets play an important role in blood clotting.

  • norm - 180-320 h109 / l

level downgrade can cause intake of certain drugs, poisoning by chemicals, various infections.And as happens with hemolytic disease of the newborn, leukemia, idiopathic thrombocytopenic purpura.Increased platelet counts may occur in the postoperative period, as well as in trauma, tumors, lack of oxygen in the primary idiopathic thrombocythemia.


This immune cells.They protect our body from various infections.

  • norm - 4-9 x 10 9 Art./ L

When the body is faced with a bacterial infection, white blood cell count increased.Also, the number is growing during pregnancy and lactation, myocardial infarction, allergies, cancers.

Reducing the number of them occurs in heavily occurring infectious diseases, radiation sickness, when taking certain medicines, as well as diseases of the blood.It is common for all types of leukocytes.


This white blood cells that capture foreign microorganisms.Normally, there should be no more than 70% of the total leukocytes.If there are more, it is often said of purulent inflammation.

Eosinophils and basophils

also refer to the white blood cells.

  • Norma - 0.5-5% of the total number of white blood cells to eosinophils
  • 0-1% of the total number of white blood cells for basophils

increase their number is a sign of allergies or helminthic invasion.


It leukocytes, providing specific immunity.Those.they "remember" the infection and develop antibodies otpredelennye to those antigens, which have already met the body.

  • norm - 19-30% of the total number of leukocytes

Increase svidetelstvut an infection.The decrease is characteristic of HIV infection and certain inherited diseases.

speed (or reaction), erythrocyte sedimentation rate (ESR or ESR)

Increased speed is a major sign of inflammation in the body.

  • rate for men is 2-10 mm / h
  • rate for women - 2-15 mm / h

The increase of this indicator for no apparent reason requires immediate medical advice.

Reduced ESR in liver disease, typhoid fever, some viral infections, as well as reducing the amount of red blood cells.
