The Complete Blood Count test measures the percentage of packed red blood cells in a whole blood sample.
hematocrit
Hematocrit test measures the percentage by volume of packed red blood cells in a whole blood sample. It is used to evaluate the concentration of red blood cells in the blood and can help diagnose conditions such as anemia or dehydration.
Typically when people refer to a blood bag they mean a transfusion of packed red blood cells. A transfusion of one unit of packed red blood cells would be approximately 250 mL.
Packed Red Blood Cells
Packed red cells are prepared by removing most of the plasma from whole blood through a process called centrifugation. This centrifugation process separates the red blood cells from the plasma and other cellular components, resulting in a concentrated suspension of red blood cells. The packed red cells are then typically suspended in a small amount of saline solution before being transfused to a patient.
Whole blood is made up of 3 parts - red blood cells, plasma and a Buffy coat which contains white blood cells and platelets.
Lymph nodes are packed full of white blood cells, usually lymphocytes.
Packed, spun-down or lysed red blood cells would be better.
nothing but normal saline can be run with any blood products
Microhematocrit tubes are read according to PCV (Packed Cell Volume). After centrifuging the tube, you will need a PCV card reader to determine the amount of packed red blood cells within the sample of blood. The PCV is determined by aligning the top of the clay plug (just as it reaches the layer of red blood cells) on the zero line and then gently "rolling" the tube up the chart until the intersecting middle line is aligned where the packed red cells and Buffy coat meet. Read across the chart and you should have a percentage of red blood cells to record as a PCV.
