Detailed explanation-1: -The definition of hematocrit (hemato from the Greek haima = blood; crit from the Greek krinein = to separate) is the ratio of the volume of packed red blood cells to the total blood volume and is therefore also known as the packed cell volume, or PCV. The hematocrit is reported as a percentage or a ratio.
