Abstract To summarize and analyze the results of external quality assessment(EQA) and the on-spot inspection of the free pre-pregnancy physical examination in Inner Mongolian Autonomous Region, and to provide evidences for continuous improvement of quality management and technical service of laboratories levels. Methods: In 2 times EQA of one year, controls of 31 items in 8 categories were distributed to the participated laboratories, and all returns from these laboratories were evaluated and statistical analyzed. The results of technical survey and detection of blind samples involved in the on-spot inspection were also analyzed. Results: During 2013-2019, there were 105-109 laboratories participated in EQA, the excellent rate had increased from 6.2% to 66.0%, and the total excellent and good rate had increased from 46.0% to 97.2%. The percent of pass of 11 items less than 80% in 2013, which had increased over 85% in recent tow years. The proportion of enzyme-linked immunsorbent assay（ELISA）and chemiluminescence immunoassay（CLIA）used for detecting the serological markers of hepatitis B virus had raised obviously. The percent of pass of blind samples detection had improved remarkably in recent three years, which all were over 85% in 2019. Conclusion: Based on the integrated working pattern of EQA, on-spot inspection, professional training, notification, and appraisal of performance for 7 years, the quality indicators of laboratories have improved remarkably, which help to discover the quality problem and to provide evidence for promoting comprehensive quality management.
