Department of Laboratory Medicine, Jiangsu Province Hospital (The First Affiliated Hospital with Nanjing Medical University), Nanjing, P. R. China Background: This audit provides baseline data on the prevalence, testing pattern and yield of electrophoresis tests performed over a 6-year period in a tertiary academic China hospital. To evaluate the adequacy of the electrophoresis test request. Methods: This was a retrospective audit of all SPE, UPE and IFE tests performed on new and follow-up adult patients (aged ¡Ý18 years) from 2014 to 2019, using data from the Department of Laboratory Science of Jiangsu Province Hospital laboratory information system database. Results: A total of 47,940 cases of electrophoresis, there are 15,473 cases SPE tests (of which 25.6% were follow-up tests); have 12,531 cases UPE tests (10.2% of the tests were follow-up tests); have 19,327 cases SIFE tests (31.6% of which were follow-up tests). Hematology was the highest rate of submission and positive. SPE testing before IFE tests can effectively increase the positive rate of IFE. Conclusion: This audit provides baseline data on the prevalence of test requests, their source and the yield of electrophoresis testing in our laboratory. An increasing trend in SIFE and UIFE was evident. http://pubs.sciepub.com/ajcmr/8/2/5/ajcmr-8-2-5.pdf electrophoresis monoclonal gammopathies accuracy immunofixation
