Hematocrit (HTC) – What information does it provide from the blood count?

The hematocrit test shows the proportion of red blood cells in the blood, which provides important information about the blood’s oxygen-carrying capacity. The measurement of hematocrit levels is part of a complete blood count and is essential for the joint evaluation of red blood cell counts, hemoglobin levels, and values related to hemoglobin concentration. In medical practice, hematocrit levels are often used to diagnose various hematopoietic system problems, as well as to identify bleeding and anemic conditions.

Normal hematocrit levels for men range from 41-53%, while for women, they range from 37-44%. These values should be assessed in comparison to the reference values of the local laboratory, and it is important to keep in mind that age and gender can also influence the results. Therefore, the hematocrit test is a vital tool for assessing the state of the blood, especially when there is suspicion of bleeding or increased red blood cell production.

Normal Values and Significance of Hematocrit

The values obtained from the hematocrit test cover a wide spectrum and provide important guidance for physicians. Normal values measured in men range from 41-53%, while for women, this range is between 37-44%. In medical practice, hematocrit values are evaluated considering the number of red blood cells and the level of hemoglobin present in the blood.

These results help determine the body’s oxygen-carrying capacity, which is crucial for diagnosing various health conditions. For example, low hematocrit levels may indicate anemia, while higher levels may be a sign of increased red blood cell production. It is important to consider the patient’s age and gender when measuring hematocrit levels, as these factors can influence the results.

Measuring hematocrit levels is particularly important in cases of suspected bleeding and in the diagnosis of polycythemia. For an accurate diagnosis, hematocrit levels should be evaluated alongside other laboratory tests to obtain the most comprehensive picture of the patient’s condition. With this data, physicians are able to develop appropriate treatment plans that facilitate the patient’s recovery.

Low Hematocrit Levels and Symptoms

Low hematocrit levels are generally associated with a decrease in the number of red blood cells. There can be several causes for this, such as significant blood loss, which can occur due to menstrual bleeding, gastrointestinal bleeding, accidents, or surgical procedures. Additionally, if the production of red blood cells is insufficient, it can also lead to low hematocrit levels, for example, due to nutrient deficiencies like iron or vitamin B12, or in cases of hematological malignancies.

Symptoms of low hematocrit levels include weakness, dizziness, headaches, paleness, loss of appetite, low blood pressure, and rapid pulse. These symptoms are common signs of anemia, indicating that the body is not receiving enough oxygen. To improve the patient’s condition, appropriate treatment and a nutritious diet are essential, which can help normalize the number of red blood cells.

Other causes that can lead to low hematocrit levels include bone marrow disorders, chronic diseases, and malignancies. These factors can all contribute to a decrease in red blood cell production and may require more serious medical intervention.

Causes and Consequences of High Hematocrit Levels

High hematocrit levels, also known as HTC, indicate an increase in the proportion of red blood cells in the blood. Several factors can contribute to this, including bone marrow diseases that can cause increased red blood cell production. In such conditions, the blood’s oxygen-carrying capacity increases, which can be particularly important in chronic heart and lung diseases, where the body is constantly struggling with oxygen supply.

High hematocrit levels can also be influenced by various other factors, such as staying at high altitudes. In this case, the body adapts to lower oxygen levels, resulting in an increase in red blood cell count to improve oxygen transport efficiency. Additionally, dehydration, which reduces blood plasma volume, can also lead to high hematocrit levels.

Symptoms of high hematocrit levels include headaches, high blood pressure, a reddened face, and an increased tendency for thrombosis, which can lead to serious complications. Physicians must pay attention to rising hematocrit levels, as this can be associated with increased blood viscosity, which impairs circulation and raises the risk of cardiovascular problems. During treatment, it is important to identify and address the underlying causes, as well as to implement appropriate lifestyle and dietary changes to normalize blood counts.
