How Do You Determine Packed Cell Volume?
Packed cell volume, or hematocrit, reflects the volume of red blood cells in a given volume of blood. The red blood cells are separated from the blood sample via centrifugation, measured, and reported as a percentage of the original blood sample. Results show the average amount of circulating red blood cells, which is useful in monitoring conditions such as anemia, bleeding, dehydration and leukemia. Average hematocrit amounts vary from male to female, but are within the same range of 40 percent to 50 percent. Usually part of a CBC, or complete blood count, a hematocrit is only performed by licensed and trained health care practitioners, usually lab technicians and depending on the methodology, may be referred to as a microhematocrit.
