Part Description

LP14597-6   Platelets
Platelets are miniature fragments of cytoplasm that break off of megakaryocytes. Their primary function is to inhibit excessive hemorrhage after blood vessel injury. Platelets cling to the damaged part of the blood vessel where they become activated, recruit other platelets to the site, and begin the cascade of physical and chemical events that lead to clot formation. Activated platelets secrete cytokines, chemokines, and growth factors, all which play a role in thrombus development.When activated, platelets stimulate monocytes and neutrophils to leave the blood vessel and enter the tissue.[PMID:27226790] The normal range of platelets is 150,000 to 450,000 platelets/uL. Lower than normal platelet counts can lead to increased bleeding and is caused by a number of factors including: chemotherapy, autoimmune disorders and some medications. Increased platelets can cause hypercoagulation due to cancer, anemia, spleen removal and some medications.[MedlinePlus Encyclopedia:003647] Source: Regenstrief LOINC
