Overview

Assay conditions for detecting ASA platelet inhibition must account for collagen concentration and baseline sensitivity; leaves open standardization for human testing.

Structured PICO

Does the concentration of collagen and initial platelet sensitivity affect the measurement of aspirin-induced inhibition of platelet aggregation in normal subjects?

P
Population
20 normal subjects (human platelets)
I
Intervention
Acetylsalicylic acid (ASA) evaluated both in vitro and in vivo
O
Outcome
Inhibition of platelet aggregation by acetylsalicylic acidsurrogate

The ability to detect aspirin-induced inhibition of platelet aggregation depends on the concentration of collagen used and the baseline sensitivity of the platelets to collagen.
