Platelet Function Testing
Only a limited number of platelet function tests are available. The bleeding time assesses primary platelet plug formation but is used only in selected patients, such as in the evaluation of von Willebrand disease. This study is inaccurate for determining the risk of bleeding in patients scheduled to undergo surgical procedures. The Platelet Function Analyzer-100® (PFA-100®), an instrument designed specifically to measure platelet function, may be useful as a screening device, especially for assessing the effect of platelet inhibitor drugs. The Ultegra Rapid Platelet Function Analyzer® is a bedside instrument designed to monitor platelet inhibition by platelet glycoprotein IIb/IIIa antagonists. |

A platelet aggregation assay assesses the release reaction or secretion of platelets and their ability to aggregate. It does not assess platelet adhesion.
