normal range of platelets uk
The result is compared to a ânormalâ range, which represents the platelet count found in 95% of healthy individuals. In adults the platelet count is usually between 150 and 450 x 109/L, which means there are 150,000 to 450,000 platelets per microlitre of blood.A low platelet count (less than 150x19/L) may also be referred to as âthrombocytopeniaâ. high platelet count (more than 450x109/L), âthrombocytosisâ, is due to overproduction of platelets by the bone marrow which can be caused by certain bone marrow disorders or might simply be a side-effect of another condition (reactive thrombocytosis).
