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

Change Reason
Microscopy is a more accurate way to describe platelet estimate; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
