Blood Color Index

What is the hematocrit and the color indicator of blood? The hematocrit is an indicator of blood count, and a ratio of red blood cells to plasma volume. Color indicator shows the relative content of hemoglobin in red blood cells. Determination of hematocrit and color index of blood helps in the diagnosis of many diseases, especially if it is connected with the concentration of hemoglobin in the blood. Isolated determination of hemoglobin in blood does not give as much information as if we measure this indicator in conjunction with a hematocrit and color index of red blood cells. Here is an example. There are blood tests, in which the hemoglobin level is reduced. How to understand the general blood test what is due to decrease in hemoglobin? After all, the reasons for the drop in hemoglobin (as described in the article the reasons for high and low hemoglobin) very much, and it may be iron deficiency anemia or anemia caused by hemolysis, bleeding or concealed, as well as other varieties of anemia.

If in this situation, not only to determine hemoglobin, hematocrit, but it is possible determine whether the anemia is associated with loss of red blood cells, and if the index to determine the color, we can understand if disturbed synthesis of the hemoglobin and, therefore, is whether the anemia is normochromic to, hypochromic or hyperchromic. Determination of hematocrit and a color indicator is included in the total blood count. The increase in red blood cells observed in the following cases: malignant transformation of the polypeptide stem cells that is observed in primary polycythemia (eritremii.) Stimulation of erythropoiesis by enhanced production of erythropoietin, which is observed in secondary polycythemia due to hypoxia of various origin, tumors of the kidneys and adrenal glands, polycystic kidney disease and hydronephrosis, taking glucocorticosteroids. Reduce the liquid part of blood (plasma) is observed during dehydration, burn disease, peritonitis, taking excessive diuretics. Decreased hematocrit blood Lowered hematocrit occurs in anemia associated with a decrease in the number of red blood cells, ie, bleeding and hemolysis of red blood cells, as well as states leads to an increase in blood volume due to plasma, which occurs during pregnancy, use of excessive amounts of salt, giperalbuminemii. Norma color index of the blood in the normal color indicator of blood ranges from 0,85-1,05 Reduced Reduced blood color index color index of the blood is observed in conditions where a decreased synthesis of hemoglobin, which reduces maintenance hemoglobin or when the size of red blood cell in the direction of decreasing (microcytosis). Elevated blood color index color index increase observed in the blood macrocytosis, ie, when the erythrocyte more of their size and can accommodate a larger amount of hemoglobin, which occurs when folievodefitsitnoy and B12-deficiency anemia, receiving cytotoxic drugs, hypothyroidism.
