Verification of Automated Urinalysis Instrumentation: Analytical and Clinical Considerations


Automated methods for urinalysis promise greater efficiency, increased throughput, and improved accuracy and precision over conventional methods. This presentation provides a brief overview of urinalysis methods and describes an approach to method validation of automated urinalysis instrumentation.

Originally presented on June 20, 2023, in Salt Lake City, Utah.

After this presentation, participants will be able to:

  • Describe the chemical and physical principles behind conventional (manual) and automated methods for urinalysis testing
  • List the studies required to document method performance required by Clinical Laboratory Improvement Amendments (CLIA)
  • Apply CLIA requirements for method validation/verification to document performance characteristics of automated urinalysis methods
