Test Info
AspirinWorks? 11-Dehydrothromboxane B2 (11-dhTXB2) with Creatinine - Aspirin (which inhibits platelet cyclooxygenase) reduces the risk of thrombosis in cardiovascular disease by impairing platelet function. Patients who do not respond to the platelet inhibitory effects of aspirin are designated as aspirin resistant". The measurement of 11-dhTXB2 in urine (the principal metabolite of platelet cyclooxygenase derived thromboxane B2) may be used in individuals with cardiovascular disease prior to initiation of aspirin therapy or in individuals non-responsive to aspirin therapy.
