To qualify for ASCP MLS certification under Route 2, candidates must complete a bachelor's degree plus specific biology and chemistry coursework. While exact requirements vary by program, the ASCP standard requires:
16 semester hours, including one semester of microbiology
16 semester hours, including organic chemistry or biochemistry
College-level math (often pre-calculus or higher)
One semester for data analysis competency
Often required by bridge and master's programs
Documented clinical lab training (arranged separately)
Note: Survey or "non-majors" science courses generally do not count toward the requirement. Many programs also require science prerequisites to be completed within the last 5–10 years.
The ASCP Board of Certification (BOC) is the credentialing body for clinical lab professionals. To sit for the MLS exam, candidates must qualify under one of several routes. Most career changers and MLT bridge candidates qualify under Route 2 or Route 4.
Complete a bachelor's degree from a NAACLS-accredited Medical Laboratory Science program.
Hold a bachelor's in any field. Need 16 biology + 16 chemistry credits plus qualifying clinical experience.
Currently certified MLT (ASCP) professionals bridge to MLS by completing a bachelor's plus additional credits.
ASCP discontinued Route 3 effective January 1, 2023. Former CLA candidates should now apply under Route 2 or Route 4.
