Hematocrit is a medical term that refers to the proportion of blood volume that is made up of red blood cells. It is typically expressed as a percentage. For example, a hematocrit value of 45% means that 45% of the blood's volume consists of red blood cells. Hematocrit is an important measure in evaluating a person's overall health and can provide insight into conditions such as anemia, polycythemia, and dehydration.
