A normal platelet count in a healthy individual is between 150,000 and 450,000 per μl (microlitre) of blood (150–450 x 109/L)[15]. Ninety-five percent of healthy people will have platelet counts in this range. Some will have statistically abnormal platelet counts while having no demonstrable abnormality. However, if it is either very low or very high, the likelihood of an abnormality being present is higher.
