What is hematocrit?
The hematocrit is the proportion, by volume, of the blood that consists of red blood cells. The hematocrit (hct) is expressed as a percentage. For example, a hematocrit of 25% means that there are 25 milliliters of red blood cells in 100 milliliters of blood.Hematocrit is the percentage of red blood cells in the total blood volume. Red blood cells are vital to your health. Imagine them as the subway system of your blood. They transport oxygen and nutrients to various locations in your body. For you to stay healthy, your body needs to have the correct proportion of red blood cells.Your doctor may order a hematocrit, or Hct, test if they think you have too few or too many red blood cells.
How is the hematocrit measured?
The hematocrit is typically measured from a blood sample by an automated machine that makes several other measurements of the blood at the same time. Most of these machines in fact do not directly measure the hematocrit, but instead calculate it based on the determination of the amount of hemoglobin and the average volume of the red blood cells. Hematocrit - Usual method for determining anemia. Used to calculate indices.A hematocrit test is part of a complete blood count (CBC). Measuring the proportion of red blood cells in your blood can help your doctor make a diagnosis or monitor your response to a treatment.A lower than normal hematocrit can indicate an insufficient supply of healthy red blood cells (anemia) , A large number of white blood cells due to long-term illness, infection or a white blood cell disorder such as leukemia or lymphoma ,Vitamin or mineral deficiencies or Recent or long-term blood loss.A higher than normal hematocrit can indicate Dehydration , A disorder, such as polycythemia vera, that causes your body to produce too many red blood cells or Lung or heart disease.
What is a normal hematocrit level?
Red blood cells carry oxygen throughout your body. Having too few or too many red blood cells can be a sign of certain diseases.The hematocrit test, also known as a packed-cell volume (PCV) test, is a simple blood test.While the laboratory that tests the blood sample may have its own ranges, generally accepted ranges for hematocrit depend on your gender and age. Typical ranges are as follows:
adult men: 38.8 to 50 percent
adult women: 34.9 to 44.5 percent
Children ages 15 and under have a separate set of ranges, as their hematocrit levels change rapidly with age. The specific lab that analyzes the results will determine the normal hematocrit range for a child of a certain age.If your hematocrit levels are too low or too high, it can indicate various problems.Looking for lab cbc with diff?.
