How to read troponin results

Other platforms explain it with text and video. In Making Synapses you practice it on the patient.

Troponin is the key blood test for heart muscle injury. One number is rarely enough; the change over time tells the story.

Step by step

  1. Know the test and units

    Most labs use high-sensitivity troponin reported in ng/L. The upper normal is the 99th percentile, often specific to sex. [1]

  2. Do not wait in a STEMI

    If the ECG shows a STEMI, start reperfusion without waiting for troponin. [2]

  3. Repeat the test

    Draw a second sample after 1 to 3 hours per your protocol. An early single normal value does not rule out a heart attack. [1]

  4. Look at the change

    A clear rise or fall means acute injury. A high but stable level suggests chronic injury, as in kidney disease or heart failure. [1]

  5. Decide if it is MI

    Myocardial infarction needs acute injury plus signs of ischemia, such as chest pain, new ECG changes or new wall motion problems. [1]

  6. Think of other causes

    Sepsis, pulmonary embolism, myocarditis, severe high blood pressure, fast rhythms and kidney failure can all raise troponin. [1]

  7. Report the trend

    Give the values, times and change together with symptoms and the ECG. [2]
