Cepheid Analyzer Lab Setup Checklist
Bringing Cepheid instruments such as GeneXpert systems into a clinical laboratory involves more than unboxing and plugging in. Federal CLIA rules decide which certificate you need, how you prove the instrument performs as expected, how you run quality control, and who may run patient testing. This checklist walks through each step in order. Sound Lab Consultants (SLC) helps labs nationwide set up instruments from Cepheid and other manufacturers. SLC is independent and is not affiliated with, authorized by or endorsed by Cepheid; always follow the manufacturer's installation and operator documentation alongside this checklist.
Who this checklist is for
Physician office labs, clinics and urgent care centers adding molecular infectious disease testing testing on Cepheid systems
New independent or reference laboratories planning a first build-out
Hospitals and freestanding ERs replacing or adding an analyzer
Lab directors and technical consultants who need a repeatable go-live plan
Step 1: CLIA certificate and test complexity
CLIA certificate type is driven by the complexity of each test you perform, not by the instrument brand. The FDA assigns complexity (waived, moderate or high) to each test system, and the categorization is published in the FDA CLIA database. The certificate you need depends on the exact cartridge and system, so check each assay's complexity in the FDA CLIA database. Search the database by test system name and analyte, print or save the record, and keep it in your validation file.
Waived tests only: Certificate of Waiver
Any moderate or high complexity test: Certificate of Compliance or Certificate of Accreditation (a Certificate of Registration is issued first)
Modified FDA-cleared tests are treated as high complexity
Setup considerations specific to Cepheid systems
Molecular testing needs contamination controls, specimen handling rules and documented cartridge lot tracking; plan these before go-live. Review the manufacturer's site requirements, operator manual and package inserts before you write your verification plan, and use general instrument documentation rather than assumptions about any one model.
Step 2: File the CMS-116
Apply using Form CMS-116 through your State Agency, following its submission instructions. List each specialty and estimated annual test volume, name a qualified laboratory director, and choose your certificate type. Do not report patient results from non-waived tests until your certificate is issued and active.
Step 3: Instrument install and performance verification
For unmodified FDA-cleared or approved moderate or high complexity tests, 42 CFR 493.1253 requires the lab to verify, before reporting patient results, that it can match the manufacturer's performance specifications for accuracy, precision and reportable range, and that the manufacturer's reference intervals are appropriate for your patient population. Modified tests or lab-developed tests require full establishment of performance specifications, including analytical sensitivity and specificity.
Document site preparation: power, water quality where required, bench space, temperature and humidity
Record the manufacturer's installation and operator qualification
Accuracy: compare patient samples or reference material against a comparative method
Precision: run replicates over multiple days
Reportable range: test low and high materials across the analytical measurement range
Reference intervals: verify transferability for your population
Lab director reviews and signs the verification summary before go-live
Step 4: Calibration and calibration verification
Follow the manufacturer's calibration instructions and frequency. Under 42 CFR 493.1255, calibration verification must include at least a minimal (or zero), mid-point and maximum value near the upper limit of the reportable range, and is performed at least every six months and whenever a complete change of reagents is introduced (unless lot changes are shown not to affect results), after major preventive maintenance or replacement of critical parts, when control materials show unusual trends or shifts or fall outside acceptable limits, or when the laboratory's established schedule requires it.
Step 5: QC plan or IQCP
The CLIA default for most non-waived tests is at least two levels of external control each day of testing (42 CFR 493.1256). Labs may instead adopt an Individualized Quality Control Plan (IQCP) built on a risk assessment, a quality control plan and a quality assessment process, where the test system's built-in controls justify it. Define acceptable ranges, rules for rejecting runs and corrective action documentation.
Step 6: Proficiency testing
Enroll in a CMS-approved PT program for each regulated analyte you test (Subpart I). Test PT samples the same way as patient samples, never refer them to another lab, and keep attestations and results. For analytes without required PT, perform an alternative assessment at least twice a year.
Step 7: Personnel (Subpart M)
Subpart M sets qualifications and duties for the laboratory director, technical consultant or technical supervisor, clinical consultant, general supervisor (high complexity) and testing personnel. Keep diplomas, licenses, training records and competency assessments. Competency must be assessed using the six required elements semiannually in the first year and annually after that.
Step 8: SOPs and procedure manual
Write a procedure for every test covering specimen requirements, reagents, calibration, QC, step-by-step testing, reportable range, reference intervals, critical values and corrective action (42 CFR 493.1251). Adapt the manufacturer's package insert rather than copying it alone, and have the director approve each procedure before use.
Step 9: Safety
OSHA Bloodborne Pathogens exposure control plan and training
Chemical hygiene and Safety Data Sheets for reagents
Biohazardous waste handling and disposal contracts
Eyewash, PPE and spill kits near the Cepheid workstation
Step 10: Accreditation
Labs choosing a Certificate of Accreditation can use a CMS-approved accrediting organization such as CAP, COLA or The Joint Commission. Each adds checklist requirements on top of CLIA, so align your SOPs and records with the chosen program's standards early.
Software: compliance tracking with myLabCompliance
Paper binders and spreadsheets break down once a lab has several instruments, shifts and testing personnel. For the document and people side of compliance, we recommend myLabCompliance, a web-based CLIA compliance management platform for technical consultants, lab directors, lab owners and quality teams.
Document control for SOPs, policies and procedure manual approvals
Training records for testing personnel
Competency assessment tracking for the six required elements
Proficiency testing scheduling and PT records
Keep instrument-generated QC, calibration and maintenance data in the systems your lab and manufacturer documentation specify.
How SLC helps
SLC helps labs set up Cepheid instruments from planning through go-live: CMS-116 preparation, verification study design, QC and IQCP writing, PT enrollment, personnel files, SOPs and accreditation preparation. See the master clinical lab setup checklist for other manufacturers.
Frequently asked questions
Does Cepheid install the analyzer for me?
Installation support terms are set by Cepheid and your purchase agreement. The lab remains responsible for CLIA performance verification, QC, PT and personnel requirements.
What CLIA certificate do I need for Cepheid tests?
It depends on each test's FDA categorization. Waived-only labs need a Certificate of Waiver; any moderate or high complexity test requires a Certificate of Compliance or Accreditation.
What does 42 CFR 493.1253 require?
For unmodified FDA-cleared or approved tests, labs must verify accuracy, precision, reportable range and reference intervals before reporting patient results.
Is SLC affiliated with the manufacturer?
No. SLC is an independent consulting network that helps labs set up instruments from Cepheid and other manufacturers.
What software helps track compliance?
SLC recommends myLabCompliance for document control, training records, competency tracking and PT scheduling and records.
