COLA Laboratory Consultant: Accreditation and Inspection Help for Clinical Labs
Sound Lab Consultants (SLC) helps clinical laboratories prepare for COLA accreditation, get ready for COLA surveys, and respond to citations with documentation that holds up. Whether you run a physician office lab, a reference lab or a specialty testing site, we work alongside your laboratory director and staff to build a quality system that meets COLA criteria and CLIA requirements every day, not just on survey day.
What Is COLA Accreditation?
COLA accreditation is a CMS-approved laboratory accreditation program in which COLA surveys a clinical laboratory against criteria that meet or exceed federal CLIA requirements. A lab that earns it holds a CLIA Certificate of Accreditation and is surveyed by COLA on a two-year cycle instead of undergoing routine CLIA surveys by its state survey agency.
COLA is approved by CMS to accredit labs across CLIA specialties including chemistry, hematology, microbiology, immunology, immunohematology and pathology, and it accredits laboratories in physician offices, hospitals, reference labs, surgery centers, mobile units and other settings (cola.org). For a broader comparison of accreditors, see our guide to COLA vs CAP vs Joint Commission lab accreditation and our overview of CLIA, CAP, COLA and TJC regulations.
The COLA Accreditation Process and Survey Cycle
According to COLA's published process (cola.org/accreditation), accreditation follows these steps:
Enrollment. The lab joins COLA and receives access to the Accreditation Manual and an information packet, and uses the COLAcentral portal to communicate and track status.
Self-assessment. The lab may complete and submit a self-assessment, then correct gaps before the on-site visit.
On-site survey. A COLA surveyor or survey team, sized to the lab's complexity, visits and shares preliminary findings at the end of the survey.
Post-survey and corrective action. COLA finalizes the survey report. If criteria are non-compliant, the lab develops and implements a corrective action plan and submits documentation.
Accreditation. The lab receives a COLA Accreditation Certificate for a two-year cycle, and COLA continues to monitor performance, including proficiency testing, between surveys.
SLC can support each step: gap analysis before enrollment, running the self-assessment honestly, a mock survey before the on-site visit, and corrective action support afterward.
COLA vs CAP vs CMS State Survey
Every non-waived lab must comply with CLIA (42 CFR Part 493). What differs is who surveys you and against which checklist.
COLA
CLIA certificate type: Certificate of Accreditation
Who surveys: COLA surveyors
Standards: COLA criteria built on CLIA requirements
Cycle: Two-year cycle
Often chosen by: Physician office labs, clinics, hospitals and reference labs wanting an educational approach
CAP
CLIA certificate type: Certificate of Accreditation
Who surveys: CAP inspection teams
Standards: CAP checklists, which go beyond CLIA in many areas
Cycle: Two-year cycle
Often chosen by: Hospital, academic and reference labs, or labs whose affiliated hospitals require CAP
CMS state survey
CLIA certificate type: Certificate of Compliance
Who surveys: State survey agency on behalf of CMS
Standards: CLIA regulations and CMS interpretive guidelines
Cycle: Generally every two years
Often chosen by: Labs that do not elect an accreditor
The right choice depends on your test menu, complexity, hospital and payer expectations, and budget. We help you weigh these before you enroll. If you are preparing for either accreditor, see our CAP laboratory consultant page.
Mock Inspections
A mock inspection is a dress rehearsal for your COLA survey. We review your lab the way a surveyor would, using the COLA criteria that apply to your specialties, and give you a prioritized findings list before the real visit.
Document review: procedure manual, QC and calibration records, PT results, maintenance logs, personnel and competency files
Walkthrough of specimen handling, reagent labeling and storage, temperature monitoring and safety
Staff interviews to confirm people can explain procedures and retrieve records quickly
Written findings ranked by risk, with practical fixes and owners
Common problem areas are covered in our article on CLIA inspection deficiencies and how to avoid them.
SOP Management
Surveyors expect a complete, current, director-approved procedure manual that matches what staff actually do. We write new SOPs, update outdated ones, and set up a document control process covering:
Test procedures that reflect manufacturer instructions and your validated or verified methods
Pre-analytic and post-analytic procedures: specimen collection, rejection criteria, result reporting and critical values
Version control, director review and signature, and retirement of superseded documents
Safety, waste and equipment maintenance procedures
Quality Control, IQCP and Proficiency Testing
QC and proficiency testing (PT) are among the most closely reviewed areas of any COLA survey, and COLA continues to monitor PT performance between surveys.
Quality control: QC frequency and acceptability criteria, Levey-Jennings review, documented corrective action for failures, and director or supervisor review.
IQCP: Individualized Quality Control Plans built from a documented risk assessment, quality control plan and quality assessment monitoring. Learn more in our IQCP guide.
Proficiency testing: enrollment for regulated analytes, review of graded results, investigation of unacceptable results, and twice-yearly accuracy verification for tests without PT. See unsuccessful PT participation and the CLIA proficiency testing rule changes.
Method verification and validation records, calibration verification and reportable range.
Corrective Action Plans After COLA or CMS Citations
When a survey identifies non-compliant criteria, your response needs to show what went wrong, why, and how you have fixed it for good. We help you:
Interpret each citation and the requirement behind it
Perform root cause analysis and decide whether patient results need to be reviewed
Write a corrective action plan with responsible people, dates and monitoring
Assemble evidence of correction, such as revised SOPs, training records, QC data and audits
Escalated situations, including repeat deficiencies, PT failures or a cease-testing letter

Staff Training and Competency
CLIA requires competency assessment for testing personnel using six elements, performed semiannually in the first year and annually after that. We help you build training checklists and competency programs that surveyors can follow easily:
Initial training documentation for each test and instrument
Competency assessments covering all six CLIA competency elements
Personnel files with qualifications, education and licensure matched to each role. See CLIA personnel qualifications.
Defined responsibilities for the laboratory director, technical consultant and testing personnel

Frequently Asked Questions
What does a COLA laboratory consultant do?
A COLA laboratory consultant helps a clinical lab meet COLA accreditation criteria and the CLIA regulations behind them. Typical work includes mock inspections, writing and reviewing SOPs, setting up quality control, IQCP and proficiency testing, preparing corrective action plans after citations, and building staff training and competency programs.
How often does COLA survey a laboratory?
COLA accreditation runs on a two-year cycle with an on-site survey each cycle, according to cola.org. COLA also monitors laboratory performance, including proficiency testing, on a continuing basis between surveys.
Is COLA accreditation the same as a CLIA certificate?
No. CLIA is the federal law and certificate program administered by CMS. A lab that holds a CLIA Certificate of Accreditation chooses a CMS-approved accrediting organization such as COLA to perform its surveys instead of a routine state agency survey on behalf of CMS.
Should my lab choose COLA, CAP, or a CMS state survey?
It depends on your test menu, complexity, facility type, payer or hospital requirements and how much educational support you want. All three paths must satisfy CLIA, and we can walk through the trade-offs for your lab.
What happens if COLA cites deficiencies at our survey?
COLA finalizes a survey report, and if criteria are non-compliant the lab must develop and implement a corrective action plan and submit supporting documentation. A consultant can help perform root cause analysis, write the plan, and assemble evidence of correction.
Do you need to be on site for a mock inspection?
Not always. Many document reviews, such as SOPs, QC records, PT results and personnel files, can be done remotely, while an on-site walkthrough is useful for observing testing, storage and records retrieval. We scope the format with you.
Can you help a new lab prepare for its first COLA survey?
Yes. We help new labs build the quality system COLA will look for, including procedures, QC, method verification, PT enrollment, personnel qualification files and competency assessment, before the first on-site survey. See also new CLIA lab onboarding.
Is Sound Lab Consultants affiliated with COLA?
No. Sound Lab Consultants is an independent consulting firm. We are not affiliated with or endorsed by COLA Inc., and accreditation decisions are made solely by the accrediting organization.
