Radiation Induced Changes in Haematocrit Values of Mouse
Keywords:
haematocrit, RBC, radiation, mouse, blood, plasma, samplingAbstract
The HCT is a measurement of the volume of red blood cells as a percentage of whole blood. For automated procedures, the haematocrit is the product of the RBC and the mean cell volume (see below). For manual determinations, the haematocrit is measured after centrifugation of a microcapillary tube filled with whole blood. The percentage of blood composed of red blood cells is the haematocrit (sometimes called packed cell volume). Manual or ‘spun’ haematocrits tend to be a few percentage points higher than calculated haematocrits, because trapped plasma is included in the apparent red blood cell volume. Haematocrit is expressed as a number without units between 0.00 and 1.00. Haematocrit values for mice are generally between 0.40 and 0.50, but may range up to 0.60 depending on sampling site and fasting status or radiation induction.
