Test Overview

Test Methodology

Automated platelet induced aggregation.

Test Usage

To determine the degree of platelet inhibition from the use of P2Y12 inhibition drug therapies known as thienopyridines. These include Clopidogrel (Plavix), Prasugrel, Ticlopidine (Ticlid), and Ticagrelor.

Reference Range

180 - 376 PRU. Values less than 180 PRU may be evidence of a P2Y12 inhibitor effect.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements

Collection Offsite

Collect specimen in a 2.7 mL blue top (citrate 3.2%) tube using a 21 gauge or larger needle; do not use 1.8 mL tube. Mix by inversion. Do not centrifuge. Whole blood specimen should arrive at lab within 3 hours of collection; transport at room temperature. Collection of the blood through lines that have been previously flushed with heparin should be avoided. If the blood must be drawn through a VAD (vascular access device), the line should be flushed with 5 mL of saline and the first 5 mL of blood or six dead space volumes of the VAD discarded.
