Packed Cell Volume (PCV)
Packed Cell Volume (pronunciation: pakd sel vol-yoom), also known as Hematocrit (pronunciation: hee-muh-toh-krit), is a medical term referring to the volume percentage (%) of RBCs in blood. It is a crucial parameter in CBC tests, which are often used to diagnose and monitor various health conditions.
Etymology
The term "Packed Cell Volume" originates from the process of centrifugation, where blood cells are "packed" at the bottom of the tube, and the volume they occupy is measured. The term "Hematocrit" is derived from the Greek words "haima" (blood) and "kritēs" (judge), indicating its role in evaluating the blood's composition.
