Laboratory Reagent Expiration Tracking Inspection Checklist [FREE PDF]

Proper reagent expiration tracking is a foundational quality control requirement mandated by ISO/IEC 17025:2017, CLIA 42 CFR Part 493, and CAP accreditation standards, as the use of expired reagents can compromise analytical accuracy and patient or environmental safety. Regulatory inspections routinely identify expired reagent use as a major nonconformance, leading to corrective action requirements, accreditation suspension, or invalidation of test results. This checklist provides a structured,

  • Industry: Clinical Laboratory
  • Frequency: Monthly
  • Estimated Time: 30-45 minutes
  • Role: Quality Analyst
  • Total Items: 41
  • Compliance: ISO/IEC 17025:2017 Section 6.4 - Equipment and Reagent Management, CLIA 42 CFR 493.1252 - Reagent and Supply Criteria, CAP CHM.13600 - Reagent Expiration and Lot Tracking, GLP 21 CFR 58.83 - Reagent and Solution Labeling Requirements, OSHA 29 CFR 1910.1450 - Occupational Exposure to Hazardous Chemicals in Laboratories

Reagent Inventory Review & Expiration Status

Perform a physical audit of all reagents in use and in storage to identify any expired, near-expiry, or improperly labeled items.

  • Have all reagents in active use been checked for expiration dates prior to this inspection?
  • Are any expired reagents currently present in the active work area or in-use reagent storage?
  • Is the total number of expired reagents found during this inspection recorded?
  • Are reagents approaching expiration within 30 days flagged and prioritized for use or planned disposal?
  • Does the laboratory maintain a current master reagent inventory list with expiration dates for all reagents?

Reagent Labeling Compliance

Verify that all reagent containers are properly labeled in accordance with GLP and laboratory-specific requirements.

  • Does every reagent container display the reagent name, concentration, lot number, and expiration date?
  • Are in-house prepared or aliquoted reagents labeled with the preparation date, expiration date, and preparer's initials?
  • Are reagent labels legible and securely attached without peeling, fading, or obscuring critical information?
  • Are opened reagent containers labeled with the date first opened where stability is affected by opening?
  • Are hazardous reagents labeled in compliance with GHS/HazCom standards including pictograms and signal words?

Lot Number & Certificate of Analysis Documentation

Confirm that lot numbers are recorded in test run records and that Certificates of Analysis (CoAs) are retained for traceable reagents.

  • Are reagent lot numbers recorded in the analytical run records for each batch of testing performed?
  • Are Certificates of Analysis or manufacturer quality documentation retained for each reagent lot received?
  • Is verification of new reagent lot performance documented prior to placing the lot into routine use?
  • Are lot change records maintained showing QC performance comparison between old and new lots?
  • Can any patient or environmental result be traced back to the specific reagent lot used in analysis?

Reagent Storage Conditions & Environmental Monitoring

Inspect storage environments including refrigerators, freezers, and ambient chemical storage for compliance with manufacturer and regulatory specifications.

  • Are refrigerated reagents stored at the manufacturer-specified temperature range (typically 2–8°C)?
  • Are frozen reagents stored at the required temperature (typically ≤ -20°C or ≤ -70°C per specification)?
  • Are refrigerator and freezer temperatures logged at minimum twice daily or monitored by a continuous system?
  • Are light-sensitive reagents stored in amber containers or protected from light exposure?
  • Is the ambient temperature of the room-temperature reagent storage area within the manufacturer-specified range?
  • Are temperature excursion events for reagent storage areas documented with assessment of reagent impact?

Quality Control Reagent Performance Verification

Confirm that QC materials are within expiration, performing acceptably, and that QC failures linked to reagent issues are documented and resolved.

  • Are all quality control materials (controls, calibrators, standards) within their stated expiration dates?
  • Are QC results for the current period within established acceptance criteria for all active reagent lots?
  • Have any QC failures been investigated for potential reagent expiration or degradation as a root cause?
  • Are QC records for each reagent lot retained and available for review during this inspection?
  • Are Levey-Jennings charts or equivalent statistical QC tools used to monitor reagent performance trends over time?

Expired Reagent Quarantine, Disposal & Corrective Action

Verify that expired reagents are immediately quarantined, properly disposed of, and that affected results are assessed for corrective action.

  • Are expired reagents immediately removed from active use areas and placed in a designated quarantine zone?
  • Are quarantined expired reagents clearly labeled as 'EXPIRED - DO NOT USE' or equivalent?
  • Is the disposal of expired hazardous reagents performed in accordance with EPA and OSHA hazardous waste regulations?
  • Has a formal corrective action been initiated for any test results potentially affected by expired reagent use?
  • Is the corrective action report for expired reagent findings documented and reviewed by laboratory management?

SDS Availability & Chemical Safety Compliance

Confirm Safety Data Sheets are current and accessible for all reagents, and that personnel are trained on chemical hazards.

  • Is a current Safety Data Sheet (SDS) available for every hazardous reagent present in the laboratory?
  • Are SDSs for newly received reagents obtained and filed before the reagent is placed into service?
  • Have all laboratory personnel handling hazardous reagents completed chemical hygiene training within the past year?
  • Is the Chemical Hygiene Plan reviewed and updated at least annually?
  • Are appropriate personal protective equipment (PPE) requirements posted or documented for each reagent class?

Reagent Receipt, Acceptance Testing & Vendor Management

Verify that incoming reagents are inspected upon receipt, acceptance criteria are applied, and supplier qualification records are maintained.

  • Are incoming reagent shipments inspected upon receipt for damage, correct temperature, and expiration dates?
  • Is the date of receipt recorded in the reagent inventory log for each new shipment received?
  • Are reagents with insufficient remaining shelf life at time of receipt rejected or documented with a risk assessment?
  • Are approved supplier qualifications maintained and reviewed at least annually for critical reagent vendors?
  • Are reagent complaints or quality issues communicated back to the supplier with formal documentation?
