To ascertain if a specific test should be brought inhouse, a process for laboratory test evaluation was devised. A standardized template in the form of a checklist was created to aid clinical laboratory personnel in the introduction of new clinical laboratory testing. The checklist is designed to expedite implementation of new testing.
