Clopidogrel Response HTPR Threshold Assessment

Identify high on-treatment platelet reactivity (HTPR) to clopidogrel using VerifyNow P2Y12 reaction units (PRU >208) or platelet aggregometry, and evaluate escalation to prasugrel or ticagrelor.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Identify high on-treatment platelet reactivity (HTPR) to clopidogrel using VerifyNow P2Y12 reaction units (PRU >208) or platelet aggregometry, and evaluate escalation to prasugrel or ticagrelor

Each component has a specific meaning:

  • VerifyNow P2Y12 reaction units or platelet aggregometry — The verifynow p2y12 reaction units or platelet aggregometry recorded for the scenario being assessed.
  • Evaluate escalation — The evaluate escalation recorded for the scenario being assessed.

Note: Interpret the clopidogrel htpr result against the thresholds and context described above.

How to Use

Enter the VerifyNow P2Y12 reaction units or platelet aggregometry, evaluate escalation for the scenario you are assessing. Identify high on-treatment platelet reactivity (HTPR) to clopidogrel using VerifyNow P2Y12 reaction units (PRU >208) or platelet aggregometry, and evaluate escalation to prasugrel or ticagrelor. Use the clopidogrel htpr result to inform your calculation.
