Abstract:
Currently, the majority of platelets transfused in the United States are collected by apheresis. The recent Food and Drug Administration guidance document published maintains that a postdonation platelet count for a donor remain >100,000/μL. During apheresis procedures, platelets are released from the splenic pool into circulation. This allows for higher postdonation platelet counts than anticipated. Some current plateletpheresis instruments take this into account when determining a safe product to be collected. On other instruments, the software does not allow for this correction. This may impact collections, but is expected to be resolved with a software update.

01:18Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...

As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
