What is hematocrit or HCT in the blood test?

Hematocrit hematocrit is one of the measurements of red blood cells. In general, "co" means iron, and wherever it comes in every word, it's definitely a word to the red blood cell. Hematocrit is a percentage of the total blood volume that includes red blood cells and is measured by measuring the red blood sample in the test tube relative to the total height of the blood.

Hematocrit is always expressed as a percentage. For example, 25% hematocrit shows 25 ml of red blood cells in 100 ml of blood. The normal amount of hematocrit depends on the age and sex of the individual. The risk parameter of this parameter is higher than 60% and less than 15%.

Hematocrit and hemoglobin are taken from a person by an automatic device. Most of these devices do not directly measure hematocrit, but the amount of hematocrit is measured by the amount of hemoglobin and the average volume of red blood cells.

What causes hematocrit reduction?
It's almost the same as reducing the hemoglobin and red blood cells. Conditions like hyperthyroidism, liver cirrhosis, bone marrow failure

What causes hematocrit?
Burns, severe diarrhea, obstructive pulmonary disease, excessive loss of body water, excessive red blood cell counts, are known to be elevated factors.

Tips on hematocrit
Diseases that cause abnormal red blood cells (such as red blood cell disease) change the amount of this parameter. If the red blood cells are normal, the amount of hematocrit is three times that of hemoglobin. The hematocrit should not be measured immediately after severe bleeding.

Treatment increases and decreases hematocrit and hemoglobin
To reduce or increase hematocrit, it depends on the cause and health of the person. Minor or modest increases in hematocrit and hemoglobin need no treatment. In order to treat hematocrit and hemoglobin, it is necessary to inject intravenous iron or blood. It is also necessary to remove blood from the body to treat hematocrit enlargement.
