(Hct) (hē-mat'ō-krit)
Percentage of the volume of a blood sample occupied by cells.
Compare: plasmacrit

[hemato- + G. krinō, to separate]

haematocrit

1. A CENTRIFUGE used to separate the cells from the fluid part of the blood.
2. The proportion of the volume of cells to the total volume after the blood has been centrifuged.

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.

haematocrit

; Hct percentage, by volume, of cells within a blood sample
