Bsh platelet aggregometry
WebMultiplate multiple electrode aggregometry (MEA) is a test of platelet function in whole blood. [1] [2] The test can be used to diagnose platelet disorders, [3] [4] [5] monitor antiplatelet therapy, [6] and is also investigated as a potential predictor of transfusion requirements and bleeding risk in cardiac surgery.
