The average life span of circulating platelets is 8 to 9 days. [17] Life span of individual platelets is controlled by the internal apoptotic regulating pathway, which has a Bcl-x L timer. [18] Old platelets are destroyed by phagocytosis in the spleen and liver.
They circulate in the blood of mammals and are involved in hemostasis, leading to the formation of blood clots. Platelets release thread-like fibers to form these clots. The normal range (99% of population analyzed) for platelets is 150,000 to 450,000 per cubic millimeter. [6] If the number of platelets is too low, excessive bleeding can occur.
They keep for up to five to seven days. [1] Platelet transfusions came into medical use in the 1950s and 1960s. [1] [5] It is on the World Health Organization's List of Essential Medicines. [6] [7] Some versions of platelets have had the white blood cells partially removed or been gamma irradiated which have specific benefits for certain ...
Platelets have a life span of 5 to 9 days. Because of this, the U.S. Food and Drug Administration (FDA) expires transfuse-able platelets 5 days post-collection. Typically, hPL is produced from expired platelets that have been stored in frozen conditions no later than 7 days post-collection.
Because platelets have a shelf life of just five days, more platelet donors are always needed. Some centers are experimenting with seven-day platelets, but this requires additional testing and the lack of any preservative solutions means that the product is far more effective when fresh.

This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds. [1]
