To compare the correct recognition rates, chi-square test was used.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Test results were received from 170 laboratories for Phe, 176 for TSH, 65 for G6PD and 65 for 17-OHP. The total number of effective quantitative and qualitative results of Phe, TSH, G6PD and 17-OHP were 2520 and 2370, 2605 and 2450, 645 and 530, 645 and 645, respectively. The overall correct recognition rates for qualitative tests of Phe, TSH, G6PD and 17-OHP were 99.79 %, 99.67 %, 93.40 % and 99.84 %, and the proportion of acceptable quantitative results were 94.48 %, 98.31 %, 84.65 % and 99.84 %, respectively. There were significant differences in the rates of acceptable quantitative results of the two measurement systems for Phe, TSH and G6PD ( p<0.001); \u03c7\n 2<\/jats:sup>\n test showed significant differences in correct recognition or acceptable rates among programmes ( p<0.001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Most of the quantitative results were acceptable and the overall correct recognition rates in qualitative results approached 100%. Distributing more challenging samples and increasing the range of concentrations of EQA samples will improve standards in future assessments.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/0969141315592924","type":"journal-article","created":{"date-parts":[[2015,6,19]],"date-time":"2015-06-19T21:46:29Z","timestamp":1434750389000},"page":"175-181","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Neonatal screening external quality assessment in China, 2014"],"prefix":"10.1177","volume":"22","author":[{"given":"Kun","family":"Zhong","sequence":"first","affiliation":[{"name":"Beijing Hospital, National Centre for Clinical Laboratories, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Hospital, National Centre for Clinical Laboratories, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Falin","family":"He","sequence":"additional","affiliation":[{"name":"Beijing Hospital, National Centre for Clinical Laboratories, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiguo","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Hospital, National Centre for Clinical Laboratories, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,6,19]]},"reference":[{"key":"bibr1-0969141315592924","doi-asserted-by":"publisher","DOI":"10.1136\/jms.6.4.186"},{"key":"bibr2-0969141315592924","unstructured":"ISO (1997) Proficiency testing by interlaboratory comparisons\u2014part 1: development and operation of proficiency testing schemes.
