Helping physicians use laboratory tests.

We have described a paradigm for viewing the use of the clinical laboratory in terms of solutions to clinical problems instead of as endless lists of tests. In this regard, we have categorized many of the clinical problems that rely heavily on laboratory testing for their solutions and have suggested ways for readers to develop their own lists for their facilities. We believe that conceptualizing laboratory services in this way can help physicians to use the clinical laboratory in more effective and cost-efficient ways.
