| description | Calculation of percentage of clot strength due to the platelet activating effects of adenosine disphosphate (ADP). This is calculated based on measurements of the patient's maximum clot strength and clot strength due to ADP-induced platelet aggregation, via methods such as thrombelastography or resonance thromboelastography. Used to guide anti-platelet therapy decisions. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Clot strength | ||
| property | LenFr = Length Fraction | ||
| 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 | ||
| method | Thromboelastography.adenosine diphosphate induced | ||

| formula (readable) | {(MAadp - MAactF) / (MAk - MAactF) } x 100, where MAadp, MAactF, and MAk are the maximum amplitude induced by adenosine diphosphate, activator F, and kaolin, respectively. | ||
