a test to measure the red blood cells as a percentage of the total volume of blood. Haematocrit is the calculated number, using an analyser, whereas packed cell volume (PCV) is derived from manual measurement.

formation of blood and blood cells

presence of blood in the urine

presence of haemoglobin in the urine

loss of blood
