Medical Laboratory Technologists are health care professionals that perform medical laboratory tests on patient tissue samples, blood, and other body fluids. If a physician is unsure of a patient’s health condition after performing a physical exam or other basic medical tests, they require more information to make a diagnosis. By testing blood, body fluid, or tissue samples, medical laboratory technologists provide important information on the patient’s health. This new information allows physicians to make a clear diagnosis and other important health care decisions. Thus, the services provided by medical laboratory technologists indirectly help to prevent and treat a host of diseases, disorders, and conditions. Some of these conditions include:
Medical laboratory technologists do not diagnose, assess, treat or otherwise provide input on the patient’s condition. Their role is only to perform laboratory tests and present the results to other health care professionals. Other health care professionals such as physicians, dentists or optometrists can then interpret these results and provide a diagnosis. Medical laboratory technologists work in medical laboratories located in hospitals, blood transfusion centers and private and public health care centers.
