Medical Laboratory Scientist Salary by State (2026): MLS Pay Compared Across All 50 States

Medical laboratory scientist salary by state varies meaningfully across the U.S. — the spread between top and bottom states is wider than for most bachelor's-degree-required healthcare occupations because state CLS (Clinical Laboratory Scientist) licensure rules create dramatic barriers to entry in some states. The national median for Medical and Clinical Laboratory Technologists sits at $68,734, but state-by-state pay across the 52 states tracked here ranges widely — from $41,530 in Puerto Rico to $102,627 in New York. That spread reflects state-level cost of living, state laboratory personnel licensure requirements, the regional concentration of reference labs and academic medical centers, and the distribution of ASCP specialist credential holders by state.

This page compares the average medical lab scientist salary by state across 1688+ metropolitan and non-metropolitan areas — drawing on the Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) survey for SOC 29-2010. If you're a working MLS evaluating relocation, a NAACLS-accredited program graduate planning your first hospital lab job, or a clinical lab manager benchmarking pay across states, the state-level comparison below is the central reference point.

How MLS Salary by State Is Measured

The BLS reports state-level MLS salary through three numbers, with one important note about the SOC code structure:

• Annual median (50th percentile) — used to rank state-level pay in the table below. SOC 29-2010 (Medical Laboratory Technologists) sometimes aggregates bachelor's-prepared MLS scientists and associate-degree-prepared MLT technicians, depending on BLS reporting cycle. This site filters to bachelor's-prepared MLS pay where possible.
• Annual mean (average) — typically runs 3–6% above median; states with strong specialist credential premiums (SBB blood bank, SM microbiology, MB molecular) show wider mean-median spreads.
• Percentile distribution (P10 / P25 / P75 / P90) — P10 reflects entry-level generalist bench MLS at community hospitals; P90 reflects ASCP specialist credential holders (SBB / SM / MB / SH / SC / SCYM / SLS / DLM), molecular technologists at reference labs (LabCorp, Quest, ARUP, Mayo), and lab supervisors/managers.

The state-comparison table below applies BEA Regional Price Parity (RPP) adjustment so both nominal pay and real purchasing power are visible.

1. State CLS Licensure Requirements

The single largest non-cost-of-living driver of state-level MLS pay is state laboratory personnel licensure. Most U.S. states do not require state-issued MLS licensure (national ASCP or AMT certification is sufficient), but several states require state-level CLS or MT license on top of national certification — and these states reliably lead state-level MLS pay rankings because the licensure barrier limits entry:

• California CLS license — the most stringent state-level laboratory license in the U.S. Requires a year of post-bachelor clinical training plus state exam through the California Department of Public Health. California consistently leads U.S. MLS pay because the licensure barrier strictly limits supply.
• Other state-licensure states — Florida, New York, Louisiana, Montana, Nevada, North Dakota, Rhode Island, Tennessee, West Virginia, Hawaii, Georgia, and others require state-level CLS or MT license in addition to national certification. State licensure barriers correlate with higher pay floors.
• National certification-only states — most states accept ASCP, AMT, or AAB national certification without state license. These states show more competitive MLS labor markets with pay tracking general healthcare-tech wage levels.
• State CLS license reciprocity — California and a few other licensure states have limited reciprocity, requiring out-of-state MLS to obtain a state license before working. The reciprocity barrier supports higher pay floors in stricter states.

2. State Cost of Living: Nominal vs Real Pay

Cost of living drives nominal state-level MLS salary. California, Hawaii, Washington, Oregon, Massachusetts, Connecticut, New York, New Jersey, Alaska lead the nominal pay rankings. After BEA RPP adjustment, the real-purchasing-power gap narrows. Texas, Florida, Tennessee, and Washington — no-state-income-tax states or low-cost states with strong reference lab density — deliver strong real-dollar take-home for MLS.

3. State Demand-Supply Dynamics for MLS

State-level MLS pay reflects the demand-supply balance:

• State reference lab concentration — North Carolina (LabCorp HQ), Massachusetts (Quest sites + biotech labs), Utah (ARUP HQ at the University of Utah), Minnesota (Mayo Clinic Laboratories HQ), Georgia (LabCorp Atlanta facilities), Texas (Quest Houston + Eurofins), California (multiple Quest + LabCorp sites + biotech contract labs) concentrate reference lab employment. Reference lab states support strong MLS pay because of high-throughput molecular and specialty testing demand.
• State academic medical center density — Massachusetts, Maryland, Pennsylvania, Minnesota, Texas, North Carolina, California, Ohio concentrate academic medical centers and NCI-designated cancer centers requiring specialty MLS (molecular, blood bank, microbiology). These states drive upper-percentile MLS pay.
• State blood center concentration — California, New York (NYBC), Pennsylvania (NYBC partnership), Minnesota, Texas, Washington, Wisconsin have major American Red Cross, Vitalant, OneBlood, NYBC, Bloodworks Northwest operations. Strong blood-center concentration supports SBB-credentialed MLS pay above state baseline.
• State public health lab and CDC infrastructure — Georgia (CDC HQ), Maryland (NIH, FDA labs), North Carolina (CDC ERFL, EPA RTP), New Mexico, Tennessee concentrate federal lab employment with strong pension and PSLF eligibility.
• State biotech industry concentration — Massachusetts (Cambridge biotech cluster), California (San Francisco Bay biotech + San Diego), North Carolina (RTP), Maryland (Frederick / Gaithersburg), Texas (Houston Texas Medical Center + Austin biotech) drive industry MLS pay above clinical baseline.
• State HPSA concentration — rural and shortage states routinely offer $5,000–$25,000 sign-on bonuses for MLS positions, especially at critical-access hospital labs running 24/7 with single bench technologists.

4. ASCP Specialist Credentials by State

ASCP specialist credentials — SBB (Blood Banking), SM (Microbiology), MB (Molecular Biology), SH (Hematology), SC (Chemistry), SCYM (Cytometry), SLS (Lab Safety), DLM (Lab Management) — distribute unevenly by state and shape upper-percentile state pay distributions:

• SBB (Blood Banking) — concentrate at major blood-center markets (California, New York, Pennsylvania, Texas, Minnesota, Washington, Wisconsin, Maryland).
• SM (Microbiology) and MB (Molecular Biology) — concentrate at reference lab and academic medical center markets (North Carolina, Massachusetts, Utah, Minnesota, Texas, California).
• DLM (Diplomate in Laboratory Management) — concentrate at major-metro hospital systems.

How to Compare MLS Salary by State Effectively

When comparing the average medical lab scientist salary by state, work through this checklist:

• Verify state CLS licensure requirement first — California, Florida, New York, Louisiana, Montana, Nevada, North Dakota, Rhode Island, Tennessee, West Virginia, Hawaii, Georgia have state-level licensure on top of national ASCP/AMT. Plan for the additional licensing process before relocating to these states.
• Compare nominal and real (cost-adjusted) pay together — a state with the highest nominal median can have lower real purchasing power if its cost of living is higher.
• Check state income tax — MLS in Texas, Florida, Tennessee, Nevada, Washington, Wyoming, South Dakota, Alaska, and New Hampshire keep more of every dollar.
• Compare percentile distribution, not just median — states with strong specialist credential premiums show wide P75–P90 spreads.
• Factor in setting mix — academic medical center states (Massachusetts, Maryland, Pennsylvania, Minnesota), reference lab states (North Carolina, Utah, Texas), and biotech states (Massachusetts, California, North Carolina) all have distinct MLS pay distributions.
• Consider specialist credential trajectory — if you plan to earn SBB, SM, or MB credentials, target states with corresponding specialty employer density.

2026 State-Level MLS Salary Outlook

MLS pay has grown at a compound annual rate of 3.04% nationally over the past five years — driven by chronic laboratory workforce shortages widely documented by the ASCP and ASCLS, rapid expansion of molecular diagnostics and next-generation sequencing volume at reference labs, and growing demand from precision-oncology and infectious-disease testing. States with rapid reference lab expansion (North Carolina, Texas, Utah, Minnesota), strict-licensure states with structural supply limits (California, Florida, New York), and rural shortage states using state-funded loan repayment to recruit (Montana, Wyoming, North Dakota, Alaska, West Virginia) are seeing the fastest state-level pay growth through 2026. The BLS projects Medical and Clinical Laboratory Technologists employment growth supporting continued upward pressure on state-level wages, especially for SBB, MB, and DLM-credentialed senior MLS.
