Few hires carry more weight in a lab than the laboratory director. Under CLIA, the director is ultimately responsible for the lab's overall operation and administration. That covers testing quality, personnel, proficiency testing, and the lab's compliance with applicable rules. When the role sits empty, or the wrong person fills it, the whole lab feels it.
Yet most lab director searches start the same way: someone copies an old job description, posts it, and waits. This guide is for the people running that search, including hospital administrators, reference-lab executives, pathology group partners, and physician-practice owners. It covers how to hire a laboratory director who is qualified, who fits your lab, and who will stay.
"Laboratory director" means different things depending on the complexity of testing your lab performs. CLIA sets different director qualifications for waived, moderate-complexity, and high-complexity testing (see 42 CFR Part 493, Subpart M). A candidate who qualifies to direct a moderate-complexity lab may not qualify for a high-complexity lab.
Before writing a word of the job posting, confirm:
Getting this wrong is expensive. You can spend months interviewing people who were never eligible for the job.
As with pathologists, the same title covers several very different jobs.
Hospital and health-system labs. The director works inside a clinical organization. They deal with medical staff, nursing, the C-suite, and accreditation bodies, often across multiple sites. Leadership and diplomacy matter as much as technical depth.
Reference and commercial labs. Volume, turnaround, automation, and cost per test drive the job. The right director has already led at that scale and is comfortable with productivity metrics and rapid test-menu growth.
Physician-office and specialty practice labs. Many of these need a director who covers part-time or oversees several small labs, sometimes remotely between required on-site visits. Practical availability and a clear agreement about responsibilities matter more than a long CV.
Diagnostics and molecular startups. Here the director often builds the quality system from scratch, works directly with R&D and commercial teams, and helps bring new assays to market. Candidates need comfort with ambiguity and with growth.
Write the setting into the search first. A strong reference-lab director can struggle in a hospital, and the reverse is just as true.
Be clear about what you are actually hiring for. Some organizations need an MD/DO pathologist who serves as laboratory director and also signs out cases. Others need a PhD scientist who runs the technical operation, with physician oversight arranged separately. Still others need an operations-focused lab manager or administrator, which is a different role from CLIA director altogether.
Blending these into one requisition is one of the most common reasons lab leadership searches stall. Sort out the structure before you go to market.
Qualified laboratory directors, especially for high-complexity labs, are a small pool, and most of them are employed and busy. They aren't scanning job boards. They respond to people they know and to opportunities presented with real specifics: test menu, volume, reporting lines, growth plans, and why the role is open.
That's why a posting typically turns up candidates who aren't qualified or aren't the right fit. Directors worth hiring usually come from targeted outreach and long-standing relationships in the lab and pathology community.
Lab director transitions are often foreseeable. Retirements, practice sales, and expansions into new testing all give some notice. The labs that handle them well start the search early, document the outgoing director's processes, and plan the handoff so compliance records don't fall through the cracks.
Running a lab while the director role is open, or covered by someone stretched across too many labs, puts pressure on everyone, and it's often when documentation starts to slip.
For high complexity testing (42 CFR 493.1443), the main pathways are a licensed MD/DO board-certified in anatomic and/or clinical pathology; a licensed MD, DO, or DPM with at least 2 years of experience directing or supervising high complexity testing plus 20 CE credit hours; or a doctoral scientist with HHS-approved board certification, the required experience, and 20 CE credit hours. Moderate complexity (42 CFR 493.1405) allows more pathways, including physicians with 1 year of directing or supervising nonwaived testing, and certain master's- and bachelor's-level candidates with supervisory experience, all with 20 CE credit hours. Directors who were qualified and serving continuously since December 28, 2024 are grandfathered, and some states add their own licensure on top of CLIA.
Yes. For high complexity testing, a doctoral scientist can qualify with an earned doctorate in a chemical, biological, clinical, or medical laboratory science (or another doctorate that meets the coursework or thesis requirements), current certification by an HHS-approved board, at least 2 years of relevant laboratory and supervisory experience, and 20 CE credit hours (42 CFR 493.1443(b)(3)). For moderate complexity, the doctoral pathway also requires board certification, plus at least 1 year directing or supervising nonwaived testing (42 CFR 493.1405(b)(3)). Board certification is the requirement most often missed when screening PhD candidates.
There's no standard timeline. It depends on the lab's complexity, setting, location, and compensation, and on how many qualified people are open to a move. Searches for high complexity directors commonly take several months from intake to start date once you add notice periods and any state licensure or credentialing. That's why starting before the role is vacant makes such a difference.
Yes, within limits. CLIA allows one individual to direct no more than five laboratories (42 CFR 493.1407(d) for moderate complexity and 493.1445(d) for high complexity). Directors must also be on-site at least once every 6 months, with at least 4 months between the two minimum visits, document those visits, and stay available for phone or electronic consultation. If your arrangement involves multiple sites, confirm with your state agency or accreditor how they are counted.
The laboratory director is a CLIA-defined role responsible for the lab's overall operation and administration, including personnel competency, PT, QC, and regulatory compliance (42 CFR 493.1407 and 493.1445). "Lab manager" isn't a CLIA title. It usually means the person running day-to-day operations such as staffing, scheduling, budgets, and workflow, who may also hold a CLIA role like technical consultant or supervisor if qualified. A director can delegate duties but remains responsible for making sure they are done properly.
Possibly. In October 2026, CMS published proposed rule CMS-3478-P, which includes proposed changes to personnel qualifications, with comments due December 7, 2026. A proposed rule isn't enforceable and may change before it's finalized, so hire against the requirements in effect today and revisit them if a final rule is published.
