(PCV), hematocrit: A laboratory test to monitor the relative number of red blood cells present in the blood. A blood sample is placed in a tiny glass tube and spun in a centrifuge. The cells are heavier than the plasma and are compacted at one end of the tube. After the tube is spun, it is examined and the packed cell volume is determined as the percentage of the red cellular portion relative to the total amount of blood in the tube (ie, remainder being the plasma). ...

The packed cell volume (PCV) or hematocrit (Hct) is a measure of RBC numbers, expressed as a percentage of the total volume of blood. The PCV, by common usage, has become synonymous with the Hct. Traditionally the PCV is obtained by centrifuging an anticoagulated blood sample (spun crit); with automated counters this value is calculated from the measured Mean Corpuscular Volume (MCV) and RBC count. This is the reason that laboratory values may differ slightly from in-clinic values. ...
