Average Medical Lab Technician Salary in Illinois

Medical laboratory technicians (MLTs) perform clinical tests on blood, tissue, urine, and other body specimens to help physicians diagnose disease, monitor treatment, and screen for illness. They operate automated analyzers, prepare specimens, and report quantitative results in chemistry, hematology, microbiology, immunology, and blood banking. The BLS reports a national median annual wage of $57,380 for clinical laboratory technologists and technicians, though technologists (BS degree) earn above median while technicians (associate's degree) cluster near the lower half. Demand is strong and growing — lab results influence approximately 70% of all physician clinical decisions — and the profession faces a persistent shortage of qualified workers as retiring laboratory scientists outpace new graduates.

In Illinois, medical lab technicians earn an average of $61,379 per year as of 2026, with salaries ranging from $40,403 for entry-level roles to $92,313 for the most experienced professionals — +1.0% above the national average. Pay is influenced most by credential level — ascp-certified mls (bs degree, technologist) earns $10,000–$20,000+ more annually than ascp-certified mlt (aas degree, technician), laboratory department specialty — blood bank, microbiology, and molecular pathology technicians command higher pay than core laboratory generalists, and the specific metro area within Illinois.
