When a person has significantly elevated troponin levels and, in particular, a rise and/or fall in the results from a series of tests done over several hours, then it is likely that the person has had a heart attack or some other form of damage to the heart.

What is considered a high troponin level?

For troponin concentrations 0.40 ng/mL and higher, the underlying cardiac injury is usually a myocardial infarction. Troponin concentrations of 0.04-0.39 ng/mL require serial troponin measurements and clinical correlation to interpret, as further described in the guidelines.

Is a troponin level of 14 high?

The normal range (value) for high-sensitivity cardiac troponin T test (hs-cTnT) is 14 ng/l. This cutoff for the “normal” level of troponin T was determined by looking at several studies of patients who were “apparently healthy” (no heart complaints) and had this level of troponin T in the bloodstream as a baseline.
