The Laboratory Stewardship Committee uses a coordinated, evidence-based approach to manage laboratory testing. Stewardship involves ensuring that the right test is ordered at the right time for the right patient while also making sure that the test results are appropriately interpreted and acted upon. The goal is to eliminate redundant or unnecessary tests, prevent diagnostic errors, and enhance overall efficiency. Please email us with comments/suggestions regarding laboratory testing and/or this test directory.
