It depends: In the proper setting with chest pain & abnormal electrocardiogram an elevated troponin (highly sensitive version) can indicate heart damage. However there are other possible explanations for an elevated level. These include congestive heart failure, pulmonary embolism (blood clot in the lungs) or kidney failure. The pattern of the elevation over time is also useful.

This can vary: Both troponin i and troponin t assays are used to test the blood for evidence of damage to the heart muscle. The normal range for troponin i is higher than the normal range for troponin t. In a given laboratory, the normal ranges may differ from that in another laboratory, depending upon the assay system used. Each laboratory generally publishes normal ranges for the particular assay it uses.
