Abstract: Objective To evaluate the on-spot inspection capabilities of clinical routine chemistry and coagulation tests,and hepatitis B and C immunoassays in municipal,county and private hospitals. Methods Specimens were collected from 2016 to 2017 and external quality assessments of Anhui Provincial Center for Clinical Laboratories were used to design sample examination panels,then on-spot supervision and inspection were carried out. The results were uploaded to the network platform,the allowable range of big data was used as the criterion to evaluate the testing capabilities of the hospitals in different projects according to the international evaluation scheme. Results In clinical routine chemistry tests,coagulation tests and hepatitis B and C immunoassays,the average PT scores in municipal hospitals were 95.63,99.63 and 92.50 and the passing rates were 100%,100% and 87.5%,respectively. The averages PT scores of county hospitals were 94.46,99.50 and 82.66 with the passing rates of 96.97%,100% and 68.75%,respectively. The average PT scores of private hospitals were 89.50,90.81 and 82.50 with the passing rates of 93.75%,93.75% and 56.25%,respectively. Conclusion The average PT score of the three clinical examinations was found to be more than 80 and the overall testing ability is qualified but higher in city hospitals than in county and private hospitals successively. Among the three types of hospitals,the testing capabilities of clinical routine chemistry analysis tests and hepatitis B and C immunoassays are in good state but coagulation tests need to be improved.
