platelets

thrombocytes

disc-like components of mammalian BLOOD, consisting of non-nucleated cytoplasmic fragments of large bone-marrow cells 3 μm in diameter called megakaryocytes that have entered the blood circulatory system. Platelets play an important part in BLOOD CLOTTING.

Platelets

Fragments of a large precursor cell (a megakaryocyte) found in the bone marrow. These fragments adhere to areas of blood vessel damage and release chemical signals that direct the formation of a blood clot.

Facilities can store platelets for seven days if they're stored in a container cleared or approved by FDA for 7-day storage and if individual platelet units are subsequently tested for bacterial detection using a bacterial detection device cleared by FDA and labeled for use as a "safety measure."
