The VerifyNow point-of-care device is available for monitoring patients on anti-P2Y12 therapy (clopidogrel and prasugrel). The extent of ADP-induced platelet aggregation is recorded as the Platelet Reactivity Unit (PRU) value, which is diminished by thienopyridine agents that block the P2Y12 ADP receptor.
P2Y12 reaction units (PRU):
Patients on P2Y12 Inhibition therapy : <208
Patients not on P2Y12 Inhibitor medications: 180 - 376
