New high-sensitivity test for detecting heart injury arrives May 7

April 29, 2019  //  FOUND IN: Michigan Medicine News

The new high-sensitivity Troponin T Assay, launched in the Emergency Department this February, will be rolled out across the health system on Tuesday, May 7 at 9 a.m. The new test will be available for both adult and pediatric patients and will replace the previous test that measured Troponin I.

Troponins are proteins found in the heart that help regulate muscle contraction. Troponin is released into the blood when a person experiences cardiac injury. The more damage the heart has endured, the greater the Troponin concentration will be. One type of cardiac injury is a myocardial infarction, however not all elevated troponins constitute a diagnosis of myocardial infarction.

Educational information about the new test, clinical interpretation and the importance of accurate documentation in MiChart has been distributed across the health system in preparation for the change. That information is also available on the UH/CVC internal website.

Here are a few key things you should know.

Troponin T Assay rollout:

  • When: Tuesday, May 7 at 9 a.m.
  • Troponin I will no longer be available to order electronically after May 6
  • Pathology will have both tests on May 7 only, and will transition to the new test on May 8
  • As of May 8, the Troponin I test will no longer be available
  • The higher sensitivity of the new test will mean more positive results that require interpretation
  • Educational materials have been distributed to all areas that will be affected by the change
  • Faculty and staff in need of details are encouraged to contact their service chief

Questions remaining after review of the educational materials can be addressed to Adam Stein, M.D., at adamstei@umich.edu, or Scott Visovatti, M.D., at shv@umich.edu.
