How to Become a Medical Laboratory Technician

To become a medical laboratory technician (MLT), you earn an associate degree in medical laboratory technology — typically a two-year program — then pass a national certification exam such as the ASCP Board of Certification MLT credential. Depending on your state, you may also need a license to practice.

This guide maps the full path: education, certification, licensure, pay, and how the MLT role compares with the higher-credentialed medical laboratory scientist. It is general career information, not academic, licensure, or employment advice; program and licensing rules change, so confirm current requirements with accredited schools, the certifying body, and your state board before enrolling.

What a Medical Laboratory Technician Does

Medical laboratory technicians run tests on blood, tissue, and other body fluids and prepare specimens for analysis, generating the results that physicians rely on to diagnose and monitor patients. The work is precise, procedure-driven, and central to patient care, even though it happens away from the bedside. For people who want a clinical, technical role without years of schooling, it is one of the most direct points of entry into healthcare.

According to the U.S. Bureau of Labor Statistics (BLS), clinical laboratory technologists and technicians earned a median annual wage of $61,890 in May 2024. Actual pay varies by region, employer, shift, and credential level.

The Education Path

The standard route is an associate degree from an accredited program.

• Earn an associate degree. Most aspiring MLTs complete a two-year clinical or medical laboratory technician associate degree at a community or technical college. Programs combine classroom science with supervised clinical training.
• Meet the academic prerequisites. To qualify for ASCP certification, you generally need an associate degree or at least 60 semester hours of college credit — including a minimum of six semester hours of chemistry and six of biology — from a regionally or nationally accredited institution.
• Complete clinical hours. Hands-on laboratory rotations are built into accredited programs and give you the supervised experience employers and certifying bodies expect.

Choosing an accredited program matters: certification eligibility and employer recognition both hinge on it, so verify accreditation before you enroll.

Certification: The ASCP MLT Credential

Certification is what most employers look for, and the ASCP Board of Certification MLT exam is the most widely recognized credential for the role.

• Recognition. The ASCP MLT certification is the standard credential for medical laboratory technicians and is broadly accepted across U.S. clinical laboratories.
• The exam. It is scored on a 999-point scale, with 400 as the passing score. ASCP reported that 71 percent of the 3,052 candidates who took the MLT exam in 2024 passed.
• Why it matters. Beyond meeting employer expectations, certification signals a verified baseline of competency and can support higher pay and advancement.

Always confirm the current eligibility routes and exam details directly with the certifying organization, since requirements are periodically updated.

Licensure: Check Your State

Certification and licensure are not the same thing. Certification is a national credential; licensure is a state legal requirement to practice.

A subset of states — eleven states and one territory — require MLTs to be licensed before practicing: California, Florida, Hawaii, Louisiana, Montana, Nevada, New York, North Dakota, Puerto Rico, Rhode Island, Tennessee, and West Virginia. In other states, certification alone may be sufficient for many roles. Because these lists and rules change, verify your state's current requirement with its licensing board before you apply for jobs.

MLT vs. MLS: Knowing the Difference

Job postings sometimes blur two distinct roles. Understanding the gap helps you target the right path and plan your advancement.

The practical takeaway: an MLT credential gets you into the laboratory faster, and many technicians later bridge to the MLS role by completing a bachelor's degree and additional certification — a clear ladder rather than a ceiling.

How to Stand Out When You Apply

Once credentialed, present yourself in the language employers and screening systems scan for:

• Lead with your credential and clinical hours. Your ASCP certification and supervised lab rotations are your strongest signals of readiness.
• Name specific competencies. Hematology, microbiology, specimen processing, quality control, and laboratory information systems are concrete, searchable skills.
• Show precision and reliability. Accuracy, attention to detail, and adherence to protocol are exactly the traits clinical labs prioritize.

When you build that resume, our guide on how to quantify healthcare resume achievements shows how to turn lab duties into measurable results, and the healthcare resume keywords and ATS guide explains how to mirror the terms a posting screens for.

Where you work shapes the day-to-day, too. Hospital laboratories often run around the clock, so evening, overnight, and weekend shifts are common and can come with pay differentials worth factoring into your plans. Reference labs, physician offices, blood-donation centers, and public-health labs each offer a different pace and specialty mix. Considering the setting alongside the credential helps you target roles that fit both your goals and your schedule, rather than taking the first posting that appears.

Frequently Asked Questions

How long does it take to become a medical laboratory technician? Typically about two years to complete an associate degree, plus the time to prepare for and pass a certification exam such as the ASCP MLT.

Do I need to be certified to work as an MLT? Most employers expect the ASCP MLT certification or an equivalent credential. Some states additionally require a license. Confirm both the employer's expectation and your state's rule.

How much does a medical laboratory technician earn? The BLS reported a median annual wage of $61,890 in May 2024 for clinical laboratory technologists and technicians, with variation by region, employer, and credential level.

Which states require a license for MLTs? Eleven states and one territory require licensure: California, Florida, Hawaii, Louisiana, Montana, Nevada, New York, North Dakota, Puerto Rico, Rhode Island, Tennessee, and West Virginia. Verify current rules with your state board.

What is the difference between an MLT and an MLS? An MLT holds an associate degree and works with more supervision; an MLS holds a bachelor's degree, performs more complex testing with greater autonomy, and generally earns more.

Can I advance from MLT to MLS? Yes. Many technicians complete a bachelor's degree and additional certification to move into the medical laboratory scientist role, gaining scope, autonomy, and pay.

The Bottom Line

Becoming a medical laboratory technician is a clear, credential-driven path: earn an accredited associate degree, pass the ASCP MLT certification, and confirm whether your state requires a license. The role offers a solid median wage, steady clinical work, and a defined route to advance into the medical laboratory scientist role later. This is general career guidance — verify current program, certification, and licensure requirements with the relevant authorities before you commit.
