What hematocrit shows. Norm and deviations

Hematocrit is one of the relative indicators of a complete blood count. This indicator reflects in percentage what proportion of cellular elements( erythrocytes, leukocytes and platelets) in the whole blood volume. Sometimes it is measured only by the number of red blood cells, because the vast majority of these cells, almost 99% of the total cell volume.

In simple terms, our blood consists of liquid tissue with blood cells that protect the body, carry oxygen and nutrients, and plasma that contains proteins, hormones, trace elements and enzymes. If a special anticoagulant is added to the blood test tube, the blood will split into 2 components, the blood particles will be heavier and settle to the bottom, the plasma will remain in the upper layer of the tube, so the height of the lower layer is hematocrit.

What hematocrit shows is more or less clear, but w

hat is the established norm of this indicator and what threatens with raising or raising its level, let's discuss in more detail.

Norm in women

Normal hematocrit values ​​are determined based on gender and age of a person. The hematocrit rate in the blood of women after the age of 18 can vary from 0.33 to 0.47.A slight decrease in the rate during the period of childbearing due to the physiological increase of liquid blood is also allowed, therefore a special rate of hematocrit during pregnancy is established - from 0.31 to 0.35.However, it is necessary to track the dynamics of the indicator regularly in each trimester of pregnancy in order to monitor the general state of health of the mother and the correct formation of the fetus in the womb. The number of erythrocytes in the early stage of pregnancy, at 6-10 weeks, as well as by the end of the third trimester, is especially clearly increasing.

Do not self-medicate if you find some deviations in the blood test. Not significantly increased or decreased hematocrit during pregnancy is absolutely easy to bring back to normal, with the help of special medication, for example, with iron content. But to do this, you need only after consultation with the doctor.

Hematocrit is below normal, what does this mean?

The most frequent reason for the decrease in hematocrit in the blood is anemia. This disease is caused by a lack of red blood cells, i.e. red blood cells. But, anemia is not the only reason why low hematocrit can be detected, the following conditions and diseases can provoke this phenomenon:

  • liver cirrhosis;
  • bone marrow dysfunction( or cancer);
  • malnutrition, namely the critical lack of iron, folic acid and vitamin B12 in the body;
  • impaired hemoglobin formation;
  • large blood loss;
  • large volume of blood or its dilution, for example during pregnancy or after the receipt of a large amount of liquid preparations intravenously;
  • violation of the formation of erythrocytes, their premature destruction or hemolysis( rupture) of erythrocytes;
  • sometimes, hematocrit is reduced as a result of chemical poisoning or after bites of poisonous insects, snakes, etc.

According to one indicator, it is difficult to describe the full picture of a person’s health, however, a low hematocrit indicates a shortage of red blood cells in the blood, but these cells are the main suppliers of nutrients and oxygen to all organs and tissues of the body. Inevitably, the indicator also falls during the formation of a malignant tumor, but this, by no means a reason to make sudden conclusions, is only a signal for additional examination.

If heavy blood cells predominate in the blood, the result may be its slower circulation through the vessel, ductility and the formation of plaques and blood clots. But, it is not always that the hematocrit increase is somehow related to the presence of the disease or pathology. Often, an increase in the level is of a physiological nature, or is regarded as an attempt by the organism to self-regulate and maintain the balance of various internal physiological processes. And this is achieved through the formation of new "defense mechanisms" - blood cells. So, the most common causes of elevated hematocrit are:

  • Dehydration, not enough liquid for the normal functioning of the body. Dehydration occurs due to low water consumption, or due to its large loss during diarrhea, vomiting, excessive sweating, and overheating. Thus, the red blood cells becomes larger than the liquid part of the blood.
  • Hypoxia or lack of oxygen. This phenomenon is often observed in heavy smokers, as well as in people staying in the highlands. With the onset of oxygen starvation, the body tries to compensate for the deficiency by increasing blood cells that carry oxygen and process carbon - these are red blood cells.
  • Taking certain medications, especially hormonal or with a strong diuretic effect, can lead to changes in the blood.
  • Tumors, hydronephrosis, polycystic kidney and adrenal glands are associated with impaired blood formation.
  • Chronic stress, anxiety.

What is hematocrit( hct in the blood test), for which it is responsible and what is the norm for women, we have told you in general terms. We will be glad if you share in the comments whether you knew about such a diagnostic indicator, or for what reason you found an increase or fall from the standard. All good health!
