New High Sensitivity Troponin Test Goes Live

As of May 22, Premier Health and CompuNet Clinical Laboratories have switched to a new troponin test, the High Sensitivity Troponin T (5th Generation) assay, and will discontinue the current Troponin T (4th generation) assay. This new assay is the most recent generation available and has been employed in Europe, Canada, and Asia since 2009.

A brief ROCHE webinar with detailed information can be viewed online.

When ordering the High Sensitivity Troponin T test

• Unit of Measure: The new platform reporting will be in whole numbers (ng/L rather than ng/mL).
• There are now gender-specific cutoff points: 14 ng/L for females and 22 ng/L for males.
  • Normal result: Female ≤14 ng/L; Male  ≤ 22 ng/L
  • Abnormal result: Female >14 ng/L; Male >22 ng/L
  • Critical result: Female and Male: ≥ 100 ng/L
• Assay Range: 6 – 10,000 ng/L
• Specimen Collection: Lithium Heparin Plasma ONLY

A multidisciplinary steering committee comprised of emergency medicine, cardiology, hospital medicine, laboratory, and quality personnel has met to develop education materials, criteria for reporting, and algorithms.
