In the United States, a medical laboratory scientist (MLS), medical technologist (MT), or a clinical laboratory scientist (CLS) typically earns a bachelor's degree in medical laboratory science, clinical laboratory science, or medical technology. Other routes include attaining a degree in biomedical science or in a life / biological science (biology, biochemistry, microbiology, etc.). Both routes typically requires the MLS/MT/CLS to obtain certification from a national certifying board (AAB, AMT, or ASCP) as most laboratories exceed the federal minimum requirements established by the Clinical Laboratory Improvement Amendments (CLIA).
