PAA, platelet aggregation activity. Data are presented as representative result relative of independent three determinations. Amplitude is expressed as ohms by maximum extent of platelet aggregation, and slope (rate of reaction) is determined by drawing a tangent through the steepest part of curve. Area under is a calculated area in descent drawing during platelet aggregation.
