haematocrit

the percentage of the blood volume occupied by red blood cells. The percentage is 40.5% in man.

haematocrit

the proportion by volume of blood occupied by erythrocytes (red blood cells, RBC): on average 45%, i.e. 45 mL of red cells in 100 mL of whole blood. Exercise-induced increase in haematocrit, together with measurement of haemoglobin concentration, allows estimation of change in plasma volume. Also known as packed cell volume (PCV). See also altitude acclimatization.
