| name | Clot strength arachidonate induced [Length fraction] in Blood by calculation | ||
| description | Calculation of percentage of clot strength due to arachidonic acid (AA)-induced platelet aggregation. This is calculated based on measurements of the patient's maximum clot strength and clot strength due to AA-induced platelet aggregation, via methods such as thromboelastography or resonance thromboelastography. This is the residual portion of the clot strength which is not inhibited, in response to arachidonate-induced activation of platelets. Used to guide anti-platelet therapy decisions. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Clot strength.arachidonate induced | ||
| 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 | Calculated | ||
