"This textbook suggests physicians should now think of the practice of laboratory medicine as a specialty that (1) routinely provides recommendations for test selection and interpretation of test results for all but the simplest of cases, (2) without a request from a patient facing provider, for even the most common disorders, and that (3) this service to fellow health care providers is as necessary as the interpretation of a biopsy or a radiographic image. The redefinition of laboratory medicine practice requires a source of knowledge that includes the necessary information for health care providers in all fields. We hope that Laposata’s Laboratory Medicine will be the textbook that is useful to everyone, especially those in laboratory medicine to advance redefinition of laboratory medicine, for many years to come"-- Provided by publisher.
