High sensitivity troponin I assays are now the standard of care for biomarker detection of myocardial injury and will replace the contemporary troponin I (TnI) assay. Corewell Health Beaumont Hospitals Dearborn, Farmington Hills, Grosse Pointe, Royal Oak and Troy, as well as the outpatient centers in Livonia and Lenox are changing to high sensitivity troponin lab monitoring as of Tuesday, Sept. 12, 2023.
The major advantages of the new assay are:
- Earlier rule-out of acute myocardial injury when TnI is undetectable (< 4 ng/L)
- More accurate evaluation of myocardial injury in females due to sex-specific troponin reference intervals
