LABORATORY PERFORMANCE IN A STATE PROFICIENCY TESTING PROGRAM - WHAT CAN A LABORATORIAN TAKE HOME

On February 28, 1992, the Centers for Disease Control and Prevention a nd the Health Care Financing Administration (HCFA) mandated that all r egulated laboratories must participate in a HCFA-approved proficiency program. The Wisconsin State Laboratory of Hygiene (WSLH) has approved PT programs in all areas of laboratory testing and offers proficiency testing (PT) to more than 4,000 laboratories throughout the United St ates. Data are shown for four specialties of testing for the first two PT events of 1994. Results indicate that a significant number of newl y enrolled laboratories, boarding on 10%, are likely to fail in the in itial PT event. However, nearly three-quarters of these were able to c orrect the problem before the second event. The benefits of PT, as a q uality assurance tool, presumably will be demonstrated in successful l ong-term performance.
