Clinical Laboratory Medicine is one of the fastest-growing fields in the world today. Medical technologists perform comprehensive clinical laboratory tests to achieve the goals of clinical detection of microbes and diagnosis of diseases. The main works of medical technologists include analyzing blood samples, body fluids, tissues, and other clinical samples, performing a range of complicated and quantitative tests, to target the aims of biological screening to molecular analyses. As a result, there is an increasing demand for qualified medical technologists for public health agencies, hospitals, physician’s offices, and research laboratories. A study conducted by the USA Department of Labor finds that this field is growing much faster than the national average, primarily due to the increased patients’ population and the increasing development and availability of new tests. The prospection of this occupation also looks promising in Taiwan.
