PACKED CELL VOLUME (PCV) 37% – 55%
This tests the percentage of blood
that has red blood
cells in it once plasma as been separated out. Low
PCV readings invariably lead to a diagnosis of anemia. The symptoms of anemia are rapid breathing, a lack of energy and pale gums. In severe cases, anemia can lead to coma, organ failure, hypothermia and death. An emergency blood transfusion is usually suggested, if the level of PCV falls below 20%.
