What is Hematocrit?

Hematocrit (Hct), also known as Packed Cell Volume (PCV), measures the percentage of blood volume occupied by red blood cells. It generally correlates with hemoglobin and RBC count and is used to assess anemia or polycythemia/erythrocytosis. Dehydration can falsely elevate hematocrit.
