Clinical Laboratory Analyzer Daily QC Verification Checklist [FREE PDF]

Daily quality control verification of clinical laboratory analyzers is required under CLIA 42 CFR Part 493 and CAP accreditation standards to ensure patient test results are accurate and reliable. FDA 21 CFR 820 Quality System Regulations require documented preventive maintenance and calibration procedures for all diagnostic devices used in patient care. Failure to perform and document daily QC is among the most common laboratory deficiencies cited during CAP inspections and CMS surveys.

  • Industry: Clinical Labs
  • Frequency: Daily
  • Estimated Time: 20-35 minutes
  • Role: Biomedical Engineer
  • Total Items: 34
  • Compliance: CLIA 42 CFR Part 493 Laboratory Requirements - QC and PT, FDA 21 CFR 820.72 Inspection, Measuring, and Test Equipment, AAMI ST79 Comprehensive Guide to Steam Sterilization (cross-reference for QC documentation), Joint Commission EC.02.04.01 Medical Equipment Management, CAP GEN.55500 Laboratory General Checklist - QC Requirements

Analyzer Startup & System Status

Verify the analyzer completes startup self-diagnostics without errors before QC materials are run.

  • Did the analyzer complete its automated startup self-test without error flags or alarm conditions?
  • Are all system status indicators showing a ready or operational state (no fault lights)?
  • Is the analyzer date and time synchronized with the laboratory information system (LIS)?
  • Have reagent lot numbers and expiration dates been verified and confirmed as current?
  • Are reagent levels sufficient for a full day of anticipated test volume?

QC Material Preparation & Handling

Confirm quality control materials are prepared, stored, and handled per manufacturer and CLIA requirements.

  • Are QC materials (controls) from the correct lot number documented in the current QC lot assignment record?
  • Were QC control vials stored at the correct manufacturer-specified temperature prior to use?
  • Were liquid controls equilibrated to room temperature for the manufacturer-specified time before reconstitution or aspiration?
  • Were control vials mixed per manufacturer instructions (inversion count, swirl method) without foaming?
  • Has the QC material preparation been documented including lot number, expiration date, and time of preparation?

QC Run & Results Evaluation

Execute QC runs at required levels and evaluate results against established acceptance criteria.

  • Were QC materials run at a minimum of two concentration levels (low and high) for each analyte per CLIA requirements?
  • Did all QC results fall within the laboratory's established acceptable range (mean ± 2SD or equivalent)?
  • Were Westgard rules or equivalent multi-rule criteria applied to evaluate QC results for systematic and random error?
  • Have all QC results been entered into the LIS or QC data management system with correct date, time, and operator ID?
  • Does the current QC run show no violation of a warning rule (1-2s) that would indicate a developing trend?

Calibration Status Verification

Confirm calibration is current and calibration verification has been performed within required intervals.

  • Is the current calibration within the manufacturer-specified calibration interval and documented in the equipment log?
  • Has calibration verification (using calibration verification materials) been performed within the required semi-annual interval?
  • Were calibration materials traceable to reference standards (e.g., NIST-traceable or manufacturer certified)?
  • Is there a documented corrective action procedure on file for failed calibration verification?

Daily Maintenance & Consumables Check

Complete required daily maintenance tasks including probe cleaning, waste disposal, and consumable level verification.

  • Has the sample probe been cleaned and inspected for clots, residue, or physical damage per daily maintenance schedule?
  • Has the liquid waste container been checked and emptied if at or above the fill line?
  • Have all daily maintenance tasks listed in the manufacturer's IFU been completed and documented in the maintenance log?
  • Is the printer or result output system functional and loaded with sufficient paper or media?
  • Is the biohazard sharps container in the analyzer area less than 3/4 full and properly labeled?

Corrective Action & Remediation

If QC failures occurred, document corrective actions taken before releasing patient results.

  • If QC failed, was patient testing halted until the root cause was identified and corrective action completed?
  • Was a corrective action documented in the QC log including description of the problem, action taken, and outcome?
  • Was the laboratory supervisor or medical director notified of any QC failure that required corrective action today?
  • If a reagent lot change was the identified root cause, was re-calibration and a new QC range established before resuming testing?
  • Corrective action summary or notes (if applicable)?

Analyzer Environment & Safety Conditions

Verify the analyzer operating environment meets temperature, humidity, and safety requirements.

  • Is the laboratory ambient temperature within the manufacturer-specified operating range for this analyzer?
  • Is the relative humidity in the analyzer area within acceptable range (typically 20–80% non-condensing)?
  • Is the analyzer area free of chemical hazards, spills, or biohazardous material that could contaminate the instrument or harm staff?
  • Is PPE (gloves, lab coat, eye protection) available and worn by all personnel operating the analyzer?
  • Is the analyzer cleared and approved for patient testing to begin today?
