| description | Assay is used to measure platelet P2Y12 receptor blockade known to occur with some drugs including the thienopyridine class of drugs, including clopidogrel (Plavis(r)). VerifyNow P2Y12 Assay from Accumetrics uses adenosine-5-diphosphate(ADP/PGE1) to induce platelet activation. Activated platelets bind fibrinogen in proportion to the number of expressed platelet GPIIb/IIIa receptors. Light transmittance increases as activated platelets bind and aggregate the fibrinogen-coated beads. A turbidimetric based optical detection system measures change in optical signal caused by aggregation and reports results in P2Y12 Reaction Units(PRU).

| component | Platelet aggregation | |
| property | ACnc = Arbitrary Concentration | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |
| system | PRP = Platelet rich plasma | |
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | |
