Test Usage

HS-troponin T can help to quickly rule out a type of heart attack called an NSTEMI. A normal result can be used to rule out people who do not need to go to hospital, and those with a confirmed NSTEMI can get treatment more quickly.

NSTEMI

  1. Symptoms concerning of an NSTEMI (Please note independent troponins hold little predictive value of diagnosing ACS in the context of COVID 19. Trend values are still helpful please follow trend value guide below)
  2. ECG shows non-specific or suspicious changes
  3. Treat as per clinician as ACS.
