Based on the evidence discussed above, we hypothesize that these subjects (or a portion of them) were completely healthy and had platelet count lower than 150109/L because of the combined action of sex, age and genetic background. In addition, a large number of possible confounding factors have been considered, including C-reactive protein, mean platelet volume, and use of antiplatelet drugs. Having abnormally high platelet counts or low platelet counts can also be a sign of diseases and conditions. A platelet count is usually part of a complete blood count.
