2 HEMATOCRIT: THE % OF VOLUME OF THE PACKED RED BLOOD CELLS FOLLOWING CENTERFUGATION.

3 Uses of hematocrit test Diagnosis of anemia and polycythemia Calculation of blood volume

4 Normal values It differs according to sex, age and other factors however the average range is: Adult Female 37-47. Adult male 41-51.

5 materials Microhematocrit centrifuge. Heparnized capillary tube. Microhematocrit reader. Sealing material. Equipment for sterile finger puncture.
