The Packed Cell Volume (PCV) test or Hematocrit is used to determine the proportion of blood that is made up of cells. It is employed to detect abnormalities in the count of red blood cells in the blood.

What Is Packed Cell Volume?

PCV is used to analyze blood which is made up of plasma and cells, of which red blood cells form a majority.

Red blood cells help in the transportation of oxygen throughout the body. PCV can be used to measure the percentage of red blood cells in comparison to plasma in a blood sample. PCV can indicate high or low levels of red blood cells, which may be a sign of certain diseases or conditions like anemia, polycythemia, and blood cancers.
