PACKED CELL VOLUME TEST(PCV)

A packed cell volume (PCV) test is a routine blood test that analyses and measures the proportion of red blood cells in a blood sample. It is also alternatively known as a hematocrit test and is expressed as a percentage of packed RBCs by volume in a blood sample, from which the amount of RBCs present in the body can be inferred. A packed cell volume or PCV test is a serological test that provides a comprehensive assessment of the percentage of red blood cells. The purpose of a PCV test is to assess the blood volume and the oxygen-carrying capacity of the red blood cells. A PCV test is generally ordered alongside a routine blood test (complete blood count).
