Labrador-Grenfell Health officials are reviewing dozens of medical tests for people who complained of chest pain, after a laboratory product was recalled by its manufacturer.
The product recalled on July 31 is used to determine a patient's troponin level after they complain of chest pain.
Chest pain can be a symptom of the beginning of a heart attack.
Health officials are trying to determine if anyone was harmed because of the faulty product.
The troponin test is one of a series of tools physicians use to assess chest pain.
All four health authorities reviewed thousands of troponin tests last year when a different manufacturer of a similar product issued an urgent recall.
