CADTH and Choosing Wisely Canada have convened a time-limited advisory panel to provide guidance on the minimum retesting intervals for 5 commonly used lab tests in Canada.
Lab testing is a critical component of effective patient care and is a high-volume medical activity in Canada. The importance of lab resource stewardship is being addressed by Choosing Wisely Canada through Using Labs Wisely, a consortium of more than 140 hospitals committed to driving the appropriate use of lab testing in Canada. Hospital labs participating in Using Labs Wisely identified a need for guidance on the minimum retesting intervals for commonly used lab tests, given variable hospital lab practices across Canada.
The Advisory Panel on Minimum Retesting Intervals for Lab Tests is composed of leaders from across the country, including lab experts, physician specialists, and a patient representative, and was established to provide evidence-informed consensus guidance to support decision-making in hospitals participating in this Using Labs Wisely initiative, and potentially other hospital and community labs across Canada.
Developing the Recommendations
Panel experts considered patient group input, literature reviews, and clinical expertise on the use and frequency of repeat lab testing to support development of consensus guidance on minimum retesting intervals for 5 commonly used lab tests in prespecified patient populations.
The panel will be reviewing lab tests in prespecified patient populations:
- hemoglobin A1c
- lipase panel
- thyroid stimulating hormone
- antinuclear antibody
- serum protein electrophoresis.
The final guidance will be published in the Canadian Journal of Health Technologies and on our website in spring 2024.
