hematocrit
Red cell percentage
Hematocrit is the percentage of blood volume occupied by red blood cells, typically measured by centrifuging a blood sample until cells and plasma separate.
Normal values range roughly from 36 to 52 percent, varying by sex and age.
Low hematocrit suggests anemia; high levels may indicate dehydration or other conditions.
Her hematocrit was dangerously low after the accident.
