What does the blood test mean?

As mentioned above, a blood test shows the quantitative ratio of red blood cells, hemoglobin, white blood cells, platelets and other blood components. Let's look at each one separately.

Red blood cells - the most numerous "inhabitants" of blood, they are filled with respiratory pigment - an iron-containing protein hemoglobin, which causes the red color of blood. In fact, it is the red blood cells that deliver oxygen to organs and tissues. Normally, in a healthy man, the level of red blood cells should be 4.

2-5.7 * 10 6 / μl , in women - 3.8-5.3 * 10 6 / μl .

Level of hemoglobin indicates the functional ability of the blood to carry oxygen.

In fact, hemoglobin is a protein in red blood cells that contains an iron atom. Normally in men, this indicator is 130-170 g / l, in women - 120-160 g / l.

Leukocytes are responsible for immunity and ply in the body along the movement of blood. For men and women, the normal white blood cell count is 4.50-11.

0 thousand / μl .

Hematocrit as a percentage shows the number of red blood cells in whole blood. In some diseases and conditions, for example, with renal failure or in the second half of pregnancy, it may decrease. Normally, in men, the hematocrit is at the level of 39-50%, and in women - 35-47% .

Another important blood indicator is platelets.

These are small nuclear-free cells that are involved in the process of blood coagulation. In cases of platelet deficiency, a person has increased bleeding - even a slight blow to the corner of the table can lead to the formation of a hematoma. If the platelet count is significantly higher than normal, then there is a risk of thrombosis. In men and women, the normal platelet count usually ranges from 150-400 thousand / μl .
