Interpreting p2y12 assay

WebBackground: The use of platelet function testing has been advocated to individualize the time needed between discontinuation of P2Y12 inhibitors and coronary artery bypass grafting (CABG). However, the use of specific point-of-care assays to predict bleeding risk in patients on P2Y12 inhibitors prior to CABG has not been fully validated. WebThere also was a strong agreement between ADP + PGE1 aggregometry and VerifyNow-P2Y12 assay (93% vs. 95% average inhibition across all donors). The coefficient of variation for the test precision was less than 8%. The VerifyNow-P2Y12 readings were not influenced by age, platelet count, hematocrit, fibrinogen, cholesterol, or triglycerides level.
