Abstract:
Objective To explore the differences of using different analytic quality requirements in the comparable validation of blood cell analysis multi-system range test comparable schemes for establishing appropriate analysis quality standards for laboratory.Methods According to WS/T 407-2012 Guideline for Comparability Verification of Quantitative Results in Medical Institution,the range test comparable method was established.According to different sources of analytic quality requirements from the WS/T 406-2012 Analysis Quality Requirements of Clinical Hematological Detection Routine Items,the US Clinical Laboratory Improvement Amendment (88),GB/T 20470-2006 Requirements of External Quality Assessment for Clinical Laboratories and biological variations,corresponding analysis quality requirements standard was designed.Results With the standards designed by using WS/T 406-2012,CLIA′-88 and GB/T 20470-2006 as the analysis quality requirements,only the comparison results of low concentration levels in 3 items of HBC,PLT and HCT were not passed,while other results all were passed;all results passed the consistency verification by suitably revising the analytic quality requirements of low value concentrations.With the biological variations as the analysis quality requirement,the comparison results in WBC three concentration levels,and HBG high and low concentration levels were passed,but other results were not passed.Conclusion The biological variations analytical quality requirements are relative demanding.Using WS/T 406-2012 Analysis Quality Requirements of Clinical Hematological Detection Routine Items and GB/T 20470-2006 Requirements of External Quality Assessment for Clinical Laboratories,fully considering the suitability of low concentration quality requirements and formulating appropriate analysis quality standards of laboratory are the important contents of laboratory comparable validation scheme.
