The median pay is about $62,930 a year. Across everyone in the job it runs from about $38,910 at the lower end to about $100,990 at the upper end. The source is listed under Sources at the end of this page.
4 to 5 years after high school, on the usual route.
$30,000 to $45,000 all in for tuition, fees, exams and kit. Living costs are not counted.
It depends where you work. You need a license, certificate or registration in California, Florida, Hawaii, Louisiana, Montana, North Dakota, Nevada, New York, Tennessee and West Virginia. Elsewhere there is none to hold, though many employers still ask for training or a certificate.

The national median is $62,930 a year, the bottom tenth earn $38,910 or less and the top tenth $100,990 or more, in the 2025 survey. The survey reports laboratory technologists and technicians together, so these figures cover both, in every kind of lab.

The bottom tenth and bottom quarter of laboratory technologists and technicians, 2025
New graduates usually start in this part of the range, though the survey publishes no separate starting figure. Night and weekend shifts carry a differential, and labs run around the clock so those shifts are always available.
$47,650 to $81,450
Half of all workers in the 2025 survey earn between these two figures
You climb by specializing, in blood banking, microbiology or molecular testing, or by moving into supervision. Travel laboratory contracts are another option.
Roughly, all in
$30,000 to $45,000
Tuition, fees, exams and kit. Not rent, food or travel
The low end is two years at a community college at under $4,000 a year, then transferring into a public university bachelor's degree at in-state rates, plus the certification exam and a state license where one is required. The high end is four straight years of in-state public tuition at roughly $11,000 a year with the same exam and license fees on top. Out-of-state and private tuition runs far higher and is not counted here. Hospitals short of laboratory staff often pay a sign-on bonus or part of the tuition in exchange for a two year commitment, so ask before you borrow.

Shift differentials
Evening, night and weekend hours pay extra, and the lab never closes.
Hospital benefits
Health cover, retirement savings with a match, and paid time off on a proper schedule.
Employer paid certification upkeep
Many labs cover your continuing education and renewal fees.
Public Service Loan Forgiveness
Nonprofit and public hospitals usually qualify, so ten years of payments can clear the rest of federal student loans.
The exact path from high school to qualified.
A science degree plus a clinical year, then a national certification exam. About four years in total.
High school
Grades 11 and 12
Biology and chemistry above all. Labs are chemistry with consequences.
Bachelor's degree
4 years
Either a medical laboratory science degree, or a biology or chemistry degree plus a separate clinical program afterwards.
Accredited clinical program
10 to 12 months
Rotations through chemistry, hematology, microbiology, immunology and blood banking. Mayo Clinic runs a 10.5 month program at sites in Minnesota, Florida and Arizona.
National certification exam
Weeks
Taken once you finish. Employers treat passing it as the real qualification, not the degree on its own.
First hospital post
Year 1
You start on one bench, usually chemistry or hematology, and rotate as you prove out.
Chemistry
The biggest single bench in most labs runs on it.
Biology
Cells, blood and bacteria are what you look at all day.
Math and statistics
Quality control is statistics, and you run it every shift.
Anything that teaches care
A mislabeled sample is a wrong diagnosis. Precision is the whole job.
Programs are accredited by NAACLS (the National Accrediting Agency for Clinical Laboratory Sciences), and graduating from an accredited one is what makes you eligible for national certification. 10 states license laboratory staff by law, according to the American Society for Clinical Laboratory Science: California, Florida, Hawaii, Louisiana, Montana, Nevada, New York, North Dakota, Tennessee and West Virginia. In the rest, certification plus an employer is enough. Separately, every lab in the country that tests human samples is regulated under CLIA (the Clinical Laboratory Improvement Amendments), which sets who is allowed to run which tests.
State universities with a laboratory science degree
The straightforward route: four years including the clinical rotations.
Hospital based clinical programs
You finish a biology or chemistry degree first, then do a 10 to 12 month clinical year at a hospital.
Mayo Clinic College of Medicine and Science
A 10.5 month accredited program at three campuses, taking students who already hold the science coursework.
Community college then transfer
Two cheap years of science, then transfer into the degree. Confirm the transfer agreement first.
Things you don't need, but that help.
Blood banking
Matching and issuing blood. High stakes, with a separate specialist certification.
Microbiology
Identifying bacteria and fungi and working out what will kill them.
Molecular diagnostics
Genetic testing, a growing part of the lab.
Cytotechnology
Reading cell samples down a microscope to find cancer early.
Laboratory management
Running the department, the budget and the inspections.
A hospital job while you study
Phlebotomy or lab assistant work gets you inside the building and ahead of other applicants.
Comfort with instruments
Modern labs are large automated analyzers, and troubleshooting them is half the job.
Data and spreadsheet skills
Quality control charts and result review run on them.
A night owl habit
The overnight shift often carries a differential and is easier to get into as a new graduate.
A huge share of what a doctor decides rests on a number your lab produced, yet patients almost never meet the person who produced it. That cuts both ways. There is no small talk, no bedside distress and no shift spent managing families, which suits a lot of people very well. It also means the work is invisible, the public does not know the job exists, and professional bodies have been briefing Congress about the resulting staffing shortage for years.
Day to day, pros and cons, where you'd work.
Start by running quality control on every analyzer before a single patient result goes out. Then samples arrive continuously: blood counts, chemistry panels, cultures to read from yesterday. You check results that look wrong, repeat them, and phone the ward immediately when something is dangerous. In between, an instrument breaks and you fix it, because nobody else will. Twelve hour shifts are common, the lab runs overnight and through holidays, and the pace is set by how sick the hospital is that day.
The good
The hard parts
Things people don't tell you.
The Centers for Medicare and Medicaid Services oversee roughly 320,000 laboratory entities under a 1988 law that sets quality standards based on how complex each test is. Who is allowed to perform a test is written into that regulation.
The American Society for Clinical Laboratory Science has led congressional briefings on the laboratory workforce shortage. O*NET OnLine (the Department of Labor's occupation database) projects average growth for the occupation, with about 20,800 job openings a year.
