Course Description

This course is aimed at preparing senior medical students for the rigors of clinical residency by educating them in the efficient selection and rational interpretation of laboratory tests. A core faculty will employ a combination of lectures and case discussion to help develop cost- and time-effective strategies for diagnosing and managing common clinical problems. Appropriate test choices, optimum clinical laboratory utilization, and limitations of tests will be emphasized. While the pathophysiological basis of laboratory testing will be emphasized, analytical methodology will be minimized. We will also address how to evaluate new tests, economics of testing, and minimizing equivocal results.

Prerequisite: Completion of required third-year clerkships.
