What's happening?

Each Fraser Health lab has a routine Troponin I method and an alternate method used as a backup and to investigate immunoassay interference. Method interference causing a false elevation in Troponin occurs in 0.1% of positive Troponin cases.

The alternate Troponin method is currently used when:

  • The routine analyzer in not available.
  • The lab identifies that there is an interfering substance in the patient sample causing the route method to be falsely elevated

The alternate Troponin method will be renamed as “Troponin I (Alt Method)” in EMR.

Troponin I

Why is this important

Observing for trending of Troponin I levels by serial samples must be done on the same method and not across methods.

How will this impact students and faculty instructors?

Students and faculty instructors who are completing student placements in Fraser Health are expected to follow this practice change to ensure that patients, clients, and residents continue to receive safe and quality care.
