Phlebotomy vs Medical Lab Technician (2026): Training & Pay

Q: "Can a phlebotomist become a medical laboratory technician?"

"Yes. Phlebotomy experience is relevant and many phlebotomists enroll in an MLT program while working. The MLT credential requires completing a NAACLS-accredited associate degree program and passing the MLT(ASCP) exam; the phlebotomy certificate alone does not qualify."

Q: "Do medical laboratory technicians draw blood?"

"Sometimes. In small hospitals and clinics, an MLT may collect samples as well as test them. In larger laboratories, phlebotomists handle collection and MLTs focus on analysis."

Q: "Is phlebotomy certification required?"

"Only a few states require it by law, but most employers require a credential such as the CPT (NHA) or PBT (ASCP). Certification also requires documented hands-on draws, which a training program provides."

Q: "How much more do lab technicians earn than phlebotomists?"

"Per BLS OEWS, May 2025, the median annual wage was $62,930 for clinical laboratory technologists and technicians (a group that includes both 2-year technicians and 4-year technologists) and $45,230 for phlebotomists."

Q: "Which has better job growth?"

"Per BLS Employment Projections, 2024-34, phlebotomists are projected to grow 5.6% with about 18,400 openings per year, while clinical laboratory technologists and technicians are projected to grow 1.7% with about 22,600 openings per year. The lab group has more total openings because of its larger workforce and replacement needs."

The short version: a phlebotomy program suits people who want a short certificate, enjoy direct patient contact, and want to enter healthcare with a focused, hands-on skill. A medical laboratory technician (MLT) program suits people who are drawn to science, prefer working with instruments and samples rather than patients, and are willing to complete a 2-year associate degree with clinical rotations to earn a nationally recognized credential. Phlebotomy is the front end of the laboratory process; the MLT works on what happens after the sample arrives.

BLS reports phlebotomists under their own occupation code, 31-9097. Medical laboratory technicians are reported within the broader group Clinical Laboratory Technologists and Technicians (29-2010), which combines 2-year technicians with 4-year technologists. The MLT figures above describe that combined group.

What a Phlebotomist Does

A phlebotomist draws blood. That is the core of the job, and it involves more than it sounds: identifying the patient correctly, selecting the right collection tubes in the right order, choosing a site and technique that suits the patient (including infants, elderly patients, and people with difficult veins), performing venipuncture or capillary collection, labeling samples accurately, and handling them so they arrive at the lab in usable condition. Phlebotomists also explain the process to nervous patients, respond when someone feels faint, and enter collection data into the lab information system.

Some phlebotomists work in a single hospital or outpatient draw station; others travel to nursing homes, patients’ homes, or workplace screening events. In blood donation centers, the role includes donor screening and monitoring. Phlebotomists work at the boundary between patients and the laboratory, and the quality of every lab result depends on the sample being collected correctly.

What a Medical Laboratory Technician Does

A medical laboratory technician analyzes samples. Once blood, urine, tissue, or other specimens arrive in the lab, the MLT prepares them, loads analyzers, runs tests in areas such as hematology, clinical chemistry, urinalysis, microbiology, immunology, and blood banking, performs quality-control checks, calibrates and troubleshoots instruments, and reports results to clinicians. MLTs work under the supervision of medical laboratory scientists (technologists) and pathologists, and in most labs the technician performs the bulk of routine, high-volume testing.

The work is scientific and detail-driven. An MLT needs to recognize when a result is implausible, when an instrument is drifting, and when a sample has been compromised, because clinicians make treatment decisions from the numbers the lab reports. Direct patient contact is limited; some MLTs also perform phlebotomy in smaller facilities, but the job is centered on the bench and the instruments.

MLTs who continue their education can complete a bachelor’s degree and qualify for the Medical Laboratory Scientist (MLS) credential, which opens supervisory, specialist, and higher-complexity testing roles.

Training and Certification Compared

Phlebotomy programs are typically a few months long and lead to a certificate. They are offered by community colleges, career schools, hospitals, and some online providers with an in-person clinical component. Coursework covers anatomy of the circulatory system, venipuncture and capillary techniques, specimen handling, infection control, safety, and medical terminology. Programs include supervised practice, and most certification bodies require a documented number of successful draws before a candidate can sit for the exam.

Certification is required by law in only a few states, but most employers require it. Common credentials include the Certified Phlebotomy Technician (CPT) from the National Healthcareer Association (NHA), the Phlebotomy Technician (PBT) from the American Society for Clinical Pathology (ASCP), and comparable credentials from AMT and NCCT. Programs should be aligned with the exam a student intends to take, since each certifying body sets its own eligibility rules.

Medical laboratory technician programs are typically 2-year associate degree programs. They should hold accreditation from the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS), which is the standard route to eligibility for the ASCP Board of Certification MLT exam. Coursework covers chemistry, biology, microbiology, hematology, immunohematology, clinical chemistry, and laboratory operations, followed by clinical practicum rotations in a working laboratory. Some NAACLS-accredited programs deliver the didactic portion online with clinical rotations arranged locally.

After graduation, candidates sit for the MLT(ASCP) exam. A minority of states license laboratory personnel and require the credential to work; elsewhere, it is an employer expectation rather than a legal requirement. ASCP requires continuing education to maintain the credential.

Bridge paths: phlebotomy is a common entry point into laboratory work. Phlebotomists who work in a hospital lab see the testing side up close, and many enroll in an MLT program while employed. Phlebotomy coursework does not typically count toward the MLT degree, but the experience is relevant and some employers support employees through the program. MLT to MLS is a well-defined progression via a bachelor’s degree.

Pay and Outlook

According to BLS OEWS, May 2025, phlebotomists (31-9097) earned a median annual wage of $45,230. Clinical laboratory technologists and technicians (29-2010), the group that includes medical laboratory technicians, earned a median of $62,930. Because that group also includes bachelor’s-level technologists, the median for 2-year MLTs alone would be expected to sit below the combined figure, though BLS does not publish the two separately.

According to BLS Employment Projections, 2024-34, employment of phlebotomists is projected to grow 5.6%, with about 18,400 openings per year on average. Employment of clinical laboratory technologists and technicians is projected to grow 1.7%, with about 22,600 openings per year. The larger openings figure for lab technologists and technicians, despite slower growth, reflects the size of the workforce and the number of workers expected to retire or change occupations.

Which Should You Choose?

If you want to start working within months, phlebotomy is the shorter path by a wide margin. It also lets you work in a laboratory environment while deciding whether to pursue the MLT degree.

If you like science and want a credentialed technical career, the MLT degree is the stronger fit. It involves chemistry, microbiology, and instrumentation at a level the phlebotomy certificate does not, and it leads to a credential that employers across the country recognize.

If you enjoy patient contact, phlebotomy provides it all day. MLT work is mostly at the bench, and some people find that isolating while others prefer it.

If you want to avoid needles or difficult draws, note that phlebotomy is entirely about collection. MLTs in larger labs rarely draw blood, though in smaller facilities they may be expected to.

If licensure is a concern, both roles have certification exams, and neither is licensed in most states. The MLT exam is broader and requires the associate degree; phlebotomy exams are narrower and can be taken after a short program.

If you are planning a longer career in the lab, MLT is the credential that continues toward MLS, specialist certifications, and supervisory roles. Phlebotomy has its own advancement track into lead phlebotomist, collections supervisor, and training roles, but the ceiling is lower without additional education.
