When you’re working in the lab day in and day out—cutting and staining slides, validating IHC, grossing specimens, performing frozen sections—it can be easy to lose sight of your bigger career goals. Maybe you’re happy with where you are now. Or maybe you’re starting to wonder if you’ve hit a ceiling.
Here’s the truth: your certification isn’t just a checkbox on your resume. It’s your professional identity. It’s what proves to hiring managers, peers, and patients that you know your craft and take it seriously.
Whether you’re a pathologists’ assistant, histotech, cytologist, or lab generalist, certification is one of the most powerful tools you can use to grow your career, command better pay, and build long-term job security. In this guide, we’ll show you which credentials matter most, how to earn them, and why they’re more than just letters after your name.
Why Certification Matters in the Lab World
In healthcare, trust is everything. The right certification tells employers that you’ve met nationally recognized standards of competency, and that you’re committed to maintaining those standards over time.
But certification isn’t just about compliance. It directly impacts your:
- Pay scale (certified professionals often earn 10-20% more)
- Job market competitiveness (especially for travel or specialty roles)
- Opportunities for promotion (supervisory or lead roles often require current credentials)
- Credibility with peers and leadership
In short, certified professionals are seen as more qualified, more prepared, and more serious about their careers. And when it comes to high-complexity labs, that matters.
Core Certifications by Role
Here’s a breakdown of the most valuable certifications for different specialties, and why each one is worth pursuing.
Certified Pathologists’ Assistants: PA(ASCP)
- Offered by: American Society for Clinical Pathology (ASCP)
- Eligibility: Completion of a NAACLS-accredited PA training program and clinical experience
- Why it matters: Most hospitals and pathology groups require it for employment. It verifies your competence in grossing, frozen sections, and autopsy techniques.
- Bonus: Certification can lead to leadership roles within pathology departments or teaching positions in PA training programs.
Histotechnologists and Histotechnicians: HT(ASCP) and HTL(ASCP)
- HT(ASCP) (Histotechnician):
- Requires an associate’s degree and completion of an accredited histotech program or on-the-job training with defined learning and specimen handling criteria.
- Ideal for entry-level lab roles
- HTL(ASCP) (Histotechnologist):
- Requires a bachelor’s degree and completion of an accredited histology program or on-the-job training with defined learning and specimen handling criteria.
- HTL certification opens doors to senior roles, quality assurance, and lab management
Both certifications demonstrate your skill in tissue processing, embedding, microtomy, and staining-essentials in surgical pathology.
Cytologists: CT(ASCP)
- Eligibility: Completion of a CAAHEP-accredited cytology program and a master’s degree.
- Why it matters: Cytology requires very specialized expertise, and CT certification is a must-have for this role.
- Career impact: Cytologists are eligible for roles in education, lab management, and even molecular diagnostics with the right additional training.
Clinical Laboratorians: MLT and MLS (ASCP or AMT)
- MLT (Medical Lab Technician):
- Designed for associate degree holders
- Ideal starting point for newer professionals or those in rural or smaller labs
- MLS (Medical Lab Scientist):
- Requires a bachelor’s degree in medical laboratory science or related field
- Often required for high-complexity testing and supervisory roles
These certifications validate your ability to perform testing across hematology, chemistry, microbiology, and blood bank—making you a flexible, highly marketable asset.
Certified Means Trusted (and More Employable)
Many lab professionals don’t realize just how much certification impacts job prospects until they start looking for a new role.
At Nicklas Laboratory Staffing, we frequently hear from lab managers and directors that certification is a deal-breaker, especially for travel or contract roles where fast onboarding and compliance are non-negotiable.
Here’s what hiring managers say they love about certified candidates:
- They require less training and get up to speed quickly
- They’re more prepared for regulatory inspections
- They tend to stay longer and have stronger professional discipline
- They’re more likely to understand workflow optimization and lab best practices
And let’s talk compensation: many organizations offer pay differentials for certified staff. Even a $2/hour increase adds up to over $4,000 per year.
Lifelong Learning and the Importance of Continuing Education
Getting certified is only the beginning. Staying certified requires ongoing learning, and that’s a good thing.
- ASCP: Requires Credential Maintenance Program (CMP) renewal every three years
- AMT: Requires annual CEU reporting to remain in good standing
These continuing education requirements help you stay current with:
- Changes to established staging and grading, grossing and staining protocols, and guidelines for testing that drives therapeutics
- Advances in testing methodologies
- Instrumentation updates
- Changes in regulatory standards
- Emerging diseases and diagnostic trends
Committing to lifelong learning not only keeps your license active. It sends a powerful signal to your employer: you’re invested in excellence.
And from a career perspective? It gives you fresh skills that could make you eligible for promotions, cross-training opportunities, or niche specialty roles.
How to Take the First Step Toward Certification
If you’re not yet certified or you’re considering leveling up from HT to HTL, or MLT to MLS—don’t overthink it. Start by researching your eligibility and creating a realistic timeline.
Here’s a quick guide:
- Visit the ASCP website and locate the certification that matches your goal
- Review eligibility requirements (education, training hours, clinical experience)
- Find study resources—online courses, flashcards, and ASCP’s own BOC Study Guides
- Check with your employer about reimbursement for prep courses or exam fees
- Set a test date giving yourself time to prepare
And don’t forget: your certification journey doesn’t have to be solo. A staffing agency like Nicklas can connect you with certified mentors, job opportunities that align with your goals, and resources to help you succeed.
