However, counts of under 50 109/L are usually monitored with regular blood tests, and those with counts of under 10-20 109/L are usually treated, as the risk of serious spontaneous bleeding, especially intra-cranial hemorrhage, is much higher with lower platelet counts. Typically, platelet counts higher than 50 109/L do not lead to clinical problems unless platelet dysfunction coexists with the low count; rather, they are picked up on a routine complete blood count.
