LOINC Code 78687-1: Platelet aggregation Qn (Bld)

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Platelet aggregation. It is commonly used with the system or sample type Bld.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: Aggregometry.thrombin receptor activating peptide-6 induced

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• Platelet aggregation [Units/volume] in Blood by thrombin receptor activating peptide-6 induced
• Platelet aggregation
• Assay 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.
