Hematology reagents used for qualitative and/or quantitative determination in plasma of thromboxane. Thromboxane A2, a product of the enzymatic conversion in platelets of prostaglandin G2, is a powerful vasoconstrictor and inducer of platelet aggregation; it is very unstable undergoing nonenzymatic hydrolysis to thromboxane B2, which is inactive. Increased levels of thromboxane in blood may indicate the occurrence of thrombosis (i.e., it is considered a thrombophilia marker).
