| name | ||
| description | Quantitative in vitro determination of platelet function in whole blood triggered by the addition of adenosine diphosphate (ADP) and prostaglandin E1 (PGE1). ADP induces platelet aggregation by two pathways mediated by the platelet receptors P2Y1 and P2Y12, respectively. The addition of PGE1 inhibits the P2Y1 activation pathway, which enables more specific evaluation of substances, such as clopidogrel, that affect platelet aggregation through the P2Y12 pathway. This term was created for, but not limited in use to, the Cobas Prostaglandin E1 Reagent used in conjunction with the ADPtest. The combination of the two is also known as ADPtest High Sensitivity (HS) assay. | |

| 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 | Bld = Whole blood | |
| 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 | |
