Platelet aggregation [Units/volume] in Blood by thrombin receptor activating peptide-6 induced   78687-1

LOINC Code


LOINC code78687-1
namePlatelet aggregation [Units/volume] in Blood by thrombin receptor activating peptide-6 induced
descriptionAssay for the quantitative in vitro determination of platelet function triggered by thrombin receptor activating peptide-6 (TRAP-6), a potent platelet activator that stimulates platelet aggregation via the thrombin receptor PAR-1. This term was created for, but not limited in use to, the Cobas TRAPtest, a platelet function assay performed on whole blood samples by impedance aggregometry method.
statusACTIVE

Fully-Specified Name

componentPlatelet aggregation
propertyACnc  =  Arbitrary Concentration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemBld  =  Whole blood
scaleQn  =  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
methodAggregometry.thrombin receptor activating peptide-6 induced
