To calculate pcv, one divides the length of packed rbcs by the total length of the packed rbcs, buffy coat, and plasma the clay plugging the bottom of the tube should not be included various microhematocrit reading devices are available. When the patient's blood sample is spun in a centrifuge, the white blood cells and platelets rise to the top in what is known as the buffy coat the heavier red blood cells sink to the bottom, where they can be calculated as a percentage of the total blood sample. What is the significance of the “buffy coat” after you centrifuge the total blood sample the “buffy coat” is a layer of white blood cells that separates the rbc layer and the plasma the “buffy coat” is a layer of white blood cells that separates the rbc layer and the plasma.

What is the significance of the “buffy coat” after you centrifuge the total blood sample the buffy coat contains all the formed elements (or cellular material) including platelets, other than rbc’s that are present in the total volume of blood. The lateral inlet is used to carefully insert the blood sample (25 ml)it is also where, after centrifugation, you collect the quantity of desired plasma to produce the final formula. Tips for working with blood samples it would be advantageous to isolate buffy coat cells or specific white blood cells as soon after the blood draw as possible .

Centrifugation of blood specimens the liquid portion of the blood after centrifugation of a specimen in which an anticoagulant close centrifuge lid and ensure . The buffy coat, which is a thin layer of leukocytes (white blood cells) mixed with platelets in the middle, and erythrocytes (red blood cells) at the bottom of the centrifuge tube.
What is the significance of the buffy coat after you centrifuge the total blood sample 3 as noted in the exercise overview, the average hematocrit for males is 42-52%, the average hematocrit for females is 37-47%, and erythropoietin is a hormone that is responsible for the synthesis of rbss. How to prepare a nucleated cell fraction from whole blood using hetasep™ 50% of the total volume 5 parts whole blood mix well centrifuge sample at room . After centrifugation, one can distinguish a layer of clear fluid (the plasma), a layer of red fluid containing most of the red blood cells, and a thin layer in between comprising less than 1% of the total volume of the blood sample, the buffy coat (so-called because it is usually buff in hue), contains most of the white blood cells and platel. Packed cell volume (pcv): this is a directly measured value obtained from centrifuging blood in a microhematocrit tube in a microhematocrit centrifuge the pcv is measured as the height of the red cell column in a microhematocrit tube after centrifugation (see image at right).
