Reference Range Information
Performing Location Reference Range
Based on preliminary manufacturer information, the recommended therapeutic range for P2Y12 inhibitors (e.g.clopidogrel) is 95-207 P2PRU. Patients with levels above this range are at risk for cardiovascular events, and those with levels below this range maybe at an increased risk of bleeding.
Interpretation
Effective August 28, 2012, percent inhibition parameter will not be available due to changes made by Accumetrics.
