Medical Technologist Job Description: Duties, Requirements, Template & Pay (2026)
A medical technologist — also titled medical laboratory scientist (MLS) or clinical laboratory scientist — performs and verifies the laboratory tests physicians use to diagnose and treat patients: chemistry, hematology, coagulation, microbiology, immunology, urinalysis and blood bank. This page covers the duties employers actually hire for, a copy-paste medical technologist job description template for hospital, reference and physician-office labs, the certification and state-license rules that matter, and what credentialed allied health applicants cost on social media from Boostpoint's 2026 benchmark.
Medical technologist duties and responsibilities
The technologist is the person who turns a tube of blood into a result a physician can act on, and who catches the result that doesn't make sense before it reaches the chart. In a hospital core lab the work is high-volume automated chemistry and hematology with a stat queue from the ED; in microbiology it's culture reading and identification; in blood bank it's crossmatching and antibody workups where a mistake is life-threatening. Technologists (bachelor's level) differ from technicians (associate level, MLT) mainly in scope: technologists perform complex tests, verify results, troubleshoot instruments and supervise. A posting should say which department, which shift and whether it's a generalist or specialist role.
Day to day, medical technologist responsibilities include:
- Perform chemical, hematologic, immunologic, microscopic and microbiological analysis of blood, urine, body fluids and tissue samples
- Operate, calibrate and maintain automated analyzers, microscopes, spectrophotometers, cell counters and coagulation instruments; troubleshoot instrument failures
- Verify results for accuracy and clinical plausibility; recognize and report critical values; repeat or reflex testing per protocol
- Run and document quality control; participate in proficiency testing and quality assurance programs; maintain CLIA, CAP and Joint Commission compliance
- Perform blood bank procedures: ABO/Rh typing, antibody screens, crossmatches, component preparation and issue
- Receive, accession and prepare specimens; identify and reject unacceptable samples
- Enter and release results in the laboratory information system (LIS); communicate with nurses and physicians on stat and critical results
- Train and supervise laboratory technicians, assistants and students; review their work
- Evaluate new methods and instruments; write and update procedures
The BLS counted about 351,200 medical and clinical laboratory technologists in 2024 (technicians are counted separately), with growth of 1–2% projected through 2034 and about 22,600 openings a year, most of them replacement openings as an aging workforce retires. The median wage was $30.26 an hour in 2025, or $62,930 a year; hospital technologists on nights and weekends, and specialists in blood bank and microbiology, earn above the median. The shortage is structural: NAACLS programs graduate far fewer technologists than labs need, which is why hospitals increasingly hire technicians and train up, and why the job description should say how it handles that. Our healthcare staffing costs page covers what lab vacancies cost when they're filled by agency.

Requirements: what's required, what's preferred, and what kills applications
Laboratory requirements are set by CLIA and, in some states, by a licensing board — but a surprising share of postings add requirements that CLIA doesn't, and lose the technicians and new graduates who could have filled the role. Allied health application completion sits at 10% of clicks in our benchmark, the second-lowest of any role family.
| Requirement | What to know |
|---|---|
| ASCP MLS certification | The industry standard, but voluntary at the federal level; CLIA sets personnel qualifications by education and training, not by certification. Many hospitals require ASCP; if you do, allow "certification within 12 months" for new graduates and technologists moving from other credentials. |
| State license | Required in roughly a dozen states (California, New York, Florida, Hawaii, Louisiana, Montana, Nevada, North Dakota, Tennessee, West Virginia and others) and not elsewhere. Check your state; in a licensing state, ask for the license number as a form field. |
| Bachelor's degree | Required for technologist-level (high-complexity) testing under CLIA. An MLT with an associate degree can perform most testing; if you'll hire an MLT and support the bridge to MLS, say so — it's the single biggest pool you can add. |
| Experience | "2+ years hospital experience" removes every new graduate in a field with too few of them. If you can orient, say "new grads welcome" and describe the orientation length. |
| Department and shift | Name them. A generalist on nights is a different job from a day-shift blood bank specialist, and technologists self-select accurately when told. |
| Physical and safety requirements | Standing, specimen handling, PPE, exposure to biological hazards. Include them; they're expected. |
| Résumé, transcripts, certification upload | Not needed to start a conversation. Ask for certification type and state license as questions; collect documents after the phone screen. |
How to customize it for your setting
Hospital core laboratory
Bed count, trauma level, analyzers, LIS and stat volume. Say whether it's a generalist rotation or fixed benches, and describe the orientation. Where hospital roles are hard to fill, our healthcare job board comparison shows which channels actually convert for credentialed staff.
Blood bank / transfusion service
A specialist posting: SBB preferred, antibody workup volume, component preparation, on-call. These technologists are scarce; lead with pay and the specialist differential.
Reference and commercial laboratories
Volume, automation, fixed shifts, often no on-call. Lead with predictability; these postings draw hospital technologists who are done with weekends.
Physician office and clinic labs
Moderate-complexity testing, daytime hours, smaller menus. Often fillable with an MLT; say so and price accordingly. The broader picture, including the caregiver-to-therapy cost split inside healthcare, is on our healthcare recruiting page.
What it costs to reach medical technologists on social
Allied health and imaging campaigns — the closest role family to laboratory roles in our 2026 Social Job Advertising Benchmark — ran a median of $54.37 per applicant across 23 campaign-months, with a wide middle band from $10.27 to $106.51, a blended figure of $25.49, and only 10% of clickers finishing the application. The healthcare and senior living sector as a whole ran $15.42 with 16% completion.
The width of that band is the point: credentialed applicants abandon long forms, and the difference between a $10 and a $100 laboratory campaign is mostly whether the application asks for a transcript upload or three tap-to-answer questions. Reaching technologists at all is the other half — most are employed, few are on job boards, and a feed ad that names the analyzer, the shift and the differential reaches every technologist within commuting distance. Agency alternatives are priced on our staffing agency markup page.
Writing the ad version
The ad is not the job description. It answers department, shift, pay and differential in the first two lines: "Medical technologists — $32–$40/hr + $6 nights, generalist core lab, Roche cobas, Epic Beaker, $10K sign-on, ASCP or eligible. [Hospital], [City]. Apply in 60 seconds." Knockout questions: certification (ASCP MLS / MLT / other / eligible), state license, department experience (multiple choice), shift preference. No résumé, no transcript.
A 15-second video of the lab, the analyzers and a technologist explaining the shift pattern beats any stock photo of a pipette. Technologists judge a lab by its instrumentation and its staffing on nights, and they'll move for better ones.
Frequently asked questions
What are the duties and responsibilities of a medical technologist?
Performing and verifying laboratory tests in chemistry, hematology, coagulation, urinalysis, microbiology, immunology and blood bank; operating, calibrating and troubleshooting analyzers; running quality control and maintaining CLIA and CAP compliance; recognizing and reporting critical values; entering results in the laboratory information system; and training and supervising technicians and students.
What is the difference between a medical technologist and a medical laboratory technician?
A medical technologist (medical laboratory scientist, MLS) holds a bachelor's degree from a NAACLS-accredited program and is qualified under CLIA to perform high-complexity testing, verify results, troubleshoot instruments and supervise. A medical laboratory technician (MLT) holds an associate degree and performs testing under the supervision of a technologist or laboratory director. Many hospitals hire MLTs and support the bridge to MLS.
What qualifications does a medical technologist need?
A bachelor's degree with completion of a NAACLS-accredited medical laboratory science program, and in most hospitals ASCP MLS certification (or an equivalent such as AMT). Roughly a dozen states also require a state clinical laboratory license. Specialist certifications in blood bank, microbiology, chemistry and hematology are preferred for specialist roles.
How much do medical technologists make?
The 2025 national median for medical and clinical laboratory technologists was $30.26 an hour, or $62,930 a year, per O*NET/BLS. Hospital technologists on evening and night shifts and specialists in blood bank and microbiology earn above the median; pay is highest in licensing states such as California and New York.
What should a medical technologist job description template include?
The department and whether the role is generalist or specialist, the shift pattern and differentials, the pay range and sign-on bonus, the analyzers and LIS in use, certification and state-license requirements, whether MLTs and new graduates are considered, physical and safety requirements, and benefits including certification and tuition support. Department, shift and pay belong in the first two lines.
