Opening a new clinical laboratory involves more regulatory steps than most new directors anticipate. The CLIA application is the most visible step, but it is not the first, and the sequence matters. Mistakes in the early steps — particularly around director qualifications and test complexity classification — can delay CLIA certification by months.
Step 1: Determine your test complexity level
Before you apply for a CLIA certificate, you need to know what tests you will perform and what complexity level they fall under. CLIA classifies tests as waived, moderate complexity, or high complexity. The complexity level determines your personnel requirements, your QC requirements, and the type of CLIA certificate you need.
Most clinical laboratories performing a meaningful test menu will operate under a certificate of compliance (for moderate and high complexity testing) or a certificate of accreditation (if you are pursuing CAP accreditation). The certificate of waiver is only appropriate for laboratories performing exclusively waived tests.
Step 2: Verify director qualifications before you apply
The CLIA application requires you to identify your laboratory director. The director must meet the personnel qualification requirements for the complexity level of testing you will perform. For high complexity testing, the director must be a physician, doctor of podiatric medicine, or hold a doctoral degree in a chemical, physical, biological, or clinical laboratory science.
This is where many new labs run into problems. The person who will serve as laboratory director may not meet the CLIA personnel qualifications for the testing they want to perform. Discovering this after the application is submitted — or after the lab is already operational — is a serious problem. Verify director qualifications before you apply.
Step 3: Complete the CLIA application accurately
The CLIA application (CMS-116) asks for information about your laboratory's location, director, testing personnel, and test menu. Errors on the application — particularly around test complexity classification and director qualifications — will delay processing and may require resubmission.
One common error is listing tests at the wrong complexity level. If you list a high complexity test as moderate complexity, your certificate will not authorize you to perform that test. Another common error is listing a director who does not meet the qualifications for the complexity level of testing you have indicated.
Step 4: Establish your quality management infrastructure before you start testing
CLIA requires that you have quality management infrastructure in place before you begin testing — not after. This includes written procedures for every test you perform, a QC program, a proficiency testing enrollment, and personnel competency documentation.
Many new labs make the mistake of starting testing before their QMS is fully established, with the intention of completing the documentation later. This is a compliance risk. If a CLIA surveyor visits before your documentation is complete, you will have deficiencies. More importantly, testing without a functioning QMS is a patient safety risk.
Step 5: Enroll in proficiency testing before you start testing
CLIA requires enrollment in an approved proficiency testing program for every regulated analyte you test. PT enrollment must be in place before you begin testing on patient specimens. The PT provider will send you samples at defined intervals; you must test them as you would patient specimens and report your results.
PT enrollment is not complicated, but it requires lead time. Most PT providers require 4–6 weeks to process enrollment and ship the first set of samples. Factor this into your startup timeline.
