If your hematocrit is low, it means that you have fewer red blood cells than is considered healthy. Hematocrit measurement is critically high if it is greater than 67% (>67%) What does it mean if your hematocrit is low?

Smoking and chronic obstructive pulmonary disease (COPD)Ī false high hematocrit may be reported if the patient has cryoproteins, significant leukocytosis, or giant platelets.

If your hematocrit is high, it means that you have more red blood cells than is considered healthy. What does it mean if your hematocrit is high? Īccording to the Cleveland clinic, the general normal ranges for hematocrit are : The average hematocrit measurement for human beings is 45%, which means that the red cell volume contains 45 mL per 100 mL of blood. Hematocrit results are reported as a percentage. What is a normal hematocrit level?ĭue to differences in age and gender, the normal hematocrit is a range. Afterward, the technician covers the surface with gauze and a bandage. Next, using a needle, the technician draws your blood. Before drawing blood for the measurement, the technician first cleans the surface from where your blood would be drawn. In the other methods, the technician draws blood from the inner side of your arm or the back of your hand. In the microhematocrit method, a technician only needs a small sample of blood from a finger-prick. However, automated analyzers may not be available in areas where resources are low.

The automated analyzer is the fastest method. The hematocrit is calculated indirectly from the average volume and the number of red blood cells. Today, these two methods have been largely succeeded by an automated hematology analyzer where the hematocrit test is obtained as part of a complete blood count (CBC) laboratory test. This ratio is then multiplied by 100 to give a certain percentage. The technician calculates hematocrit as the length of the packed red blood cell layer divided by the length of total cells and plasma. īoth procedures require the technician to manually measure the length of the layers. So the percentage of hematocrit is more accurate in the microhematocrit method than in the macrohematocrit method. The microhematocrit method traps less plasma because the diameter of the capillary tube is smaller than the Wintrobe hematocrit tube. Ī newer method is the microhematocrit method, which uses a capillary tube instead of a narrow glass tube and requires a smaller quantity of blood and less time. The macrohematocrit method carries the risk of measuring trapped plasma as part of the red blood cell layer, which erroneously elevates the hematocrit percentage. At the very top, there’s a small layer of blood plasma. The centrifuge separates the blood into three main layers: red blood cells, white blood cells, and platelets, in that order from the bottom up. It uses a narrow glass tube and a centrifuge machine. The original method for hematocrit measurement is the macrohematocrit (Wintrobe hematocrit tube) method.

If your doctor suspects that you have a blood disorder such as anemia or polycythemia (too many red blood cells), your doctor may order a hematocrit test to check your red blood cells. Hematocrit is a significant measurement as it can identify whether you have sufficient red blood cells for oxygen transportation and delivery. On their way back to your lungs, they carry carbon dioxide to be exhaled. When red blood cells pass through your lungs, they bind to and transport oxygen to various cells in your body. They contain a vital protein component called hemoglobin that binds to oxygen, which fuels all the cells in your body.

Hematocrit is important because red blood cells are essential to your survival. In a hematocrit test, the red blood cells are separated from the rest of your blood cells and plasma. The word hematocrit means to separate blood. Human blood contains red blood cells, white blood cells, and platelets suspended in a liquid called plasma. Hematocrit is also called packed cell volume (PCV) or erythrocyte volume fraction. Hematocrit (HCT) is the calculated volume percentage of red blood cells (erythrocytes) in your blood.
