HM laboratories changed from troponin I tests to high-sensitivity troponin T tests, due to Siemens (its manufacturer) withdrawing troponin I tests from the market.
The new Roche Troponin T test was the first high-sensitivity troponin method FDA approved for use in the U.S. There’s abundant literature on the clinical performance of high-sensitivity troponin assays, and chest pain center accrediting agencies consider high-sensitivity troponin assays the standard of care.
Important:
-
Troponin T results will be reported in units of ng/L, instead of the current units for Troponin I, which are ng/mL (ng/L = 1000 X ng/mL).
-
HM Emergency Care Centers will continue using the Troponin, I-STAT [POC164] test on iSTAT instruments.
