McKesson's Advanced Diagnostics Management (ADM) solution targets the exploding use of molecular and genetic tests. ADM intelligently connects payors, clinical laboratories and providers to help physicians order the most appropriate tests for the right cost at the point of care. ADM expands the RelayHealth network to allow providers to gain electronic access to labs' test catalogs and health plans' rules for eligibility, automatic pre-authorization, network coverage and price estimation. By connecting to clinical laboratories and payors, providers can inform their patients instantly of how much a test will cost, whether their health insurance will cover it and which labs are best qualified to perform the test.
