How to read manual hematocrit

 · The term "hematocrit (HCT)" originated from English “hemato-“ and Greek “krites.” HCT measures the volume of packed red blood cells (RBC) relative to whole blood. Hence, it is also known and reported as a packed cell volume (PCV). It is a simple test to identify conditions like anemia or polycythemia and also to monitor response to the treatment. A glass tube and a centrifuge machine.  · How to read Adams Micro-hematocrit Reader. The hematocrit measures percentage by volume of packed red blood cells in a whole blood sample. For example, a HCT of 40% indicates that a ml sample of blood contains 40 ml of blood cells. Packing is achieved by centrifuging anticoagulated whole blood in a capillary tube so that the cells are tightly packed without hemolysis.

Erroneous hematocrit results can be obtained by improper sample handling. n Hematocrit results can be affected by the settling of red blood cells in the collection device. The best way to avoid the affect of settling is to test the sample immediately. If there is a delay in testing of a minute or more, the sample must be remixed thoroughly. EKF Diagnostics UltraCrit™Hematocri device is a point-of-care hematocrit device delivering highly accurate measurements for blood donor screening. UltraCrit™Hematocrit Device is a unique technology, developed in the USA. It is the first and only hematocrit/hemoglobin device to use ultrasound methodology. Using the highly accurate ultrasound. Figure Place the tube on the hematocrit reader chart. It should be placed so the bottom of the rbc layer is at 0, and the top of the plasma is at ; slide the tube along the chart until you find the perfect intersections. Read the percentage at the top of the rbc layer (do not include the buffy coat). In this case the PCV is about 50%.

The hematocrit or packed cell volume (PCV) determines the percentage of red blood cells (RBCs) in whole blood. The normal hematocrit value for men is 42% to 52%; for women, 37% to 47%; and for newborns, 53% to 65%. When hematocrit determinations are below normal, medical conditions such as anemia and leukemia may be present. 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. I show how to measure a manual hematocrit, also known as a microhematocrit, Hct, Pcv (Packed Cell Volume). This number can also be calculated by a hematology.
