Embed tissue, then slice it
You set tissue in a wax block first, then cut very thin slices for slides on a microtome.
Career profile
Histotechnologist
Histotechnologists make fine tissue detail show clearly and find out why a slide went wrong.
Want precise lab work that puts biology in your hands? You prepare tissue for pathologists, troubleshoot machines and judge how well lab methods work.
A day in the life
Stain slices to reveal structures
Apply stains so structures show up, and in specialist immunohistochemistry work, mark specific proteins with antibodies.
Trace a poor stain's cause
If staining looks off under the microscope, check slide prep, stain controls and equipment before anyone accepts results.
Help trial a new stain
In some positions, you help test a new staining method, measure it against lab needs and note problems.

Fit, tradeoffs & changing tools
You might like this if…
- You enjoy precise handwork and noticing small visual differences.
- You want to understand why a procedure failed, then work through possible causes.
- You can stay careful when the same task comes around again.
Things to weigh
- Repeated hand movements and deadline pressure are part of the work; accuracy still matters when slides are piling up.
- You handle human specimens and hazardous chemicals. Protective equipment and careful handling are everyday requirements.
Where AI may help
Automated instruments can run staining steps. In some labs, scanners turn glass slides into digital images for viewing and analysis.
What people still lead
You still maintain instruments, investigate failed runs and check whether a method produces usable results.
What we can’t predict yet
How much troubleshooting can become automated remains uncertain, especially when unfamiliar tissue or a new method behaves differently.
Pay in context
Earnings
Histotechnologist-specific national pay is not reported. The broader clinical laboratory workforce offers context, but its figures are not a salary estimate for this specialty.
A broader national benchmark
Clinical laboratory technologists and technicians had a median of $62,930 a year, or $30.26 an hour, in May 2025. The lowest 10% earned below $38,910 annually; the highest 10% earned above $100,990. These are wage percentiles, not starting and senior salaries.
Openings across the broader field
For clinical laboratory technologists and technicians overall, employment is projected to grow 3% from 2025 to 2035, with about 20,800 openings annually. Many replace people who leave the occupation. Histotechnologists' share is not reported.

An employer may weigh your experience, skills and education when setting pay. Check whether a quoted range excludes overtime, shift differentials and benefits.
Getting started
Combine a degree with accredited histology training
- What the route involves
- Earn an accredited bachelor's degree with 30 semester hours across biology and chemistry, including both. Complete a Histotechnician or Histotechnologist program accredited by the National Accrediting Agency for Clinical Laboratory Sciences within the past five years.
- What it can lead to
- This meets the education and training requirements for HTL(ASCP) exam Route 1.
Build qualifying laboratory experience after college
- What the route involves
- Earn an accredited bachelor's in biological science or chemistry, or a bachelor's with 30 semester hours across both subjects. Add one year of full-time acceptable clinical histopathology experience within the past five years.
- What it can lead to
- Documented qualifying experience provides an HTL(ASCP) Route 2 option.
- What to check
- The laboratory must qualify, and experience must cover fixation, processing, embedding, sectioning, staining—including immunohistochemistry—and laboratory operations.
Two routes lead toward the American Society for Clinical Pathology (ASCP) Scientist in Histotechnology certification, HTL(ASCP). After meeting eligibility requirements, you must pass the exam.
After entry
Career paths
This starts where the entry routes leave off: early work, growing capability, and advancement or specialization. This path also has a credential or licensing boundary; see the requirements and limits.
Get dependable at the bench
Learn your lab's specimen records and workflow. Build consistency in embedding, cutting and staining before taking on unfamiliar preparations.
Handle harder preparations
Develop skill in specialized staining and tracing technical failures. Learn how to assess a method's performance, not just complete its steps.
Become a senior technical resource
A senior histotechnologist can help validate methods, tackle difficult troubleshooting and coach colleagues. This adds responsibility for how the laboratory's work holds up.
Where you can work
Large hospital pathology laboratories
You may work within a specialty team handling surgical specimens, frozen sections or specialized stains. High specimen volume shapes the pace; some positions include off-shifts, weekends or on-call work.
- Indoors
- Lab
- Shift work
- On call
- Safety-sensitive
University research cores
You prepare tissue for investigators' experiments. A project may need sections cut to particular anatomy or different preparation methods; some cores also stain and scan slides. Discussing experimental goals helps determine the work.

- Lab
Try it
See whether the job clicks before you commit to the path.
Choose an openly available teaching image of a stained tissue slide. Make a blurred or low-contrast copy, then compare them: which details became harder to see? Write two questions you would ask about slide preparation. Notice whether checking image quality makes you curious about the process behind it.
Stay safe: Use teaching images only; this is a quality-observation exercise, not diagnosis or specimen handling.
