Conduct chemical analysis of body fluids, including blood, urine, or spinal fluid, to determine presence of normal or abnormal components. Analyze laboratory findings to check the accuracy of the results. Operate, calibrate, or maintain equipment used in quantitative or qualitative analysis, such as spectrophotometers, calorimeters, flame photometers, or computer-controlled analyzers. Collect and study blood samples to determine the number of cells, their morphology, or their blood group, blood type, or compatibility for transfusion purposes, using microscopic techniques. Enter data from analysis of medical tests or clinical results into computer for storage. Establish or monitor quality assurance programs or activities to ensure the accuracy of laboratory results. Analyze samples of biological material for chemical content or reaction. Set up, clean, and maintain laboratory equipment. Provide technical information about test results to physicians, family members, or researchers. Cultivate, isolate, or assist in identifying microbial organisms or perform various tests on these microorganisms. Supervise, train, or direct lab assistants, medical and clinical laboratory technicians or technologists, or other medical laboratory workers engaged in laboratory testing. Develop, standardize, evaluate, or modify procedures, techniques, or tests used in the analysis of specimens or in medical laboratory experiments. Conduct chemical analyses of body fluids, such as blood or urine, using microscope or automatic analyzer to detect abnormalities or diseases and enter findings into computer.
