- Active MLS or MT certification from ASCP, AMT, or AAB recognized in Missouri
- Bachelor's degree in medical laboratory science or a closely related clinical discipline

Medical Laboratory Scientist Jobs in Missouri: Frequently Asked Questions
How do you become a medical laboratory scientist in Missouri?
Missouri does not issue a state-level MLS license, so the path centers on national certification. You complete a bachelor's degree in medical laboratory science or a related field that includes an accredited clinical practicum, then sit for a certifying exam through ASCP, AMT, or AAB. Missouri employers almost universally treat national certification as the hiring standard, and many require it at offer rather than allowing a grace period after starting.
Which companies hire medical laboratory scientists in Missouri?
Employers hiring medical laboratory scientists in Missouri right now include SSM Health, BJC HealthCare, and Research Medical Center, based on current listings on Migrate Mate as of October 2026. Missouri's largest integrated health systems and independent reference laboratories generate the most consistent volume of openings across both inpatient and outpatient laboratory settings.
Which Missouri cities have the most medical laboratory scientist jobs?
St. Louis, Kansas City, and Fenton have the most medical laboratory scientist openings in Missouri. St. Louis leads because of its dense concentration of academic medical centers and regional reference labs, Kansas City follows with several large health system campuses on both sides of the state line, and Columbia's openings are driven primarily by University of Missouri Health Care and the surrounding regional hospital network.
Are there remote medical laboratory scientist jobs in Missouri?
Yes, but they're rare. Medical laboratory science is fundamentally a hands-on role requiring direct specimen handling and instrument operation, so most positions are fully on-site. About 0% of medical laboratory scientist openings tied to Missouri are remote or hybrid as of October 2026, and those exceptions are almost exclusively in laboratory management, quality assurance, or data review roles that don't require bench work.
How can I get hired as a medical laboratory scientist in Missouri with little or no experience?
The most realistic entry path is applying directly to laboratory assistant or phlebotomy roles at large Missouri health systems like BJC HealthCare or SSM Health while completing or finishing an accredited MLS program. Many Missouri hospital labs offer new-graduate onboarding rotations that count toward ASCP eligibility hours. Completing your clinical practicum at a Missouri facility also puts you in front of hiring supervisors before you graduate, which is the most common way new graduates land their first staff position.
Where can I find and apply to medical laboratory scientist jobs in Missouri?
You can find and apply to medical laboratory scientist jobs in Missouri on Migrate Mate, which lists current openings from employers hiring in the state right now. Search the roles that fit your specialty and experience level and apply directly through each listing.
