The Clinical Laboratory Services industry has seen significant growth over the past few years. New state and federal laws and regulations mandate that physicians provide toxicology testing for their patients who are prescribed chronic pain relievers and other opiates. Historically, physicians have obtained lab services from large toxicology reference labs. Those labs do not always provide the flexibility and responsiveness required in your dynamic environment. Physicians are turning to specialty labs to get the customer service they require. Regionally based toxicology reference labs have stepped up to respond to the physicians’ demands. Additionally, when feasible, physicians and practitioners have realized that performing these tests in a physician owned laboratory (POL) gives them greater control of testing requisitions, improves turnaround time for faster clinical decision making, and captures a revenue stream they had previously passed to a reference laboratory. With the challenges of maintaining sustainable revenue streams in a rapidly changing managed care environment, the POL can assist by improving patient care while also elevating the overall business health of a practice. As a result, GNOS Medical has helped numerous practices gain control of their toxicology testing and improve revenue by advising in the entire startup and operation process of a CLIA certified, high-complexity toxicology laboratories.
