About Biological Technicians

Medical Laboratory Technicians perform analytical tests on blood, urine, tissue, and other biological specimens that physicians use to diagnose, monitor, and treat diseases. They operate sophisticated laboratory instruments, prepare specimens, run tests, and report results to clinical staff. MLTs work across multiple laboratory disciplines: hematology (blood cell counts and morphology), clinical chemistry (metabolic panels, enzyme levels), microbiology (identifying bacterial and fungal pathogens), immunology, blood banking, and urinalysis. Accuracy and attention to detail are paramount—laboratory results directly influence clinical decisions, and errors can have serious patient safety consequences. MLTs must follow strict quality control protocols, calibrate and maintain instrumentation, and troubleshoot unexpected results. They work in hospital laboratories, reference laboratories, physician office labs, and public health laboratories. An associate degree in medical laboratory technology and certification through the American Society for Clinical Pathology (ASCP) are standard entry requirements. MLTs work closely with medical laboratory scientists and pathologists in high-volume environments that often include night and weekend shifts.
