METHODS: Serum samples from HFMD patients and healthy adult controls were evaluated for the presence of anti-EV71 IgM using a dot-immunoenzyme filtration assay (DIEFA). The results were compared with those obtained using a dot-immunogold filtration assay (DIGFA). The EV71 structural protein VP1 was used as the antigen for both assays. RESULTS: Serum samples from 72 HFMD patients and 54 healthy controls were evaluated. The DIGFA procedure showed a sensitivity of 98.5% and a specificity of 100%, whereas the DIEFA procedure showed a sensitivity of 98.6% and a specificity of 98.0%. There were no significant differences between the assays in either specificity or sensitivity. CONCLUSION: The DIEFA procedure developed in this study has potential as a rapid, simple, sensitive and cost-effective screening technique for detecting EV71 antigen in serum samples from patients with HFMD.<\/jats:p>","DOI":"10.1177\/147323001204000332","type":"journal-article","created":{"date-parts":[[2013,2,27]],"date-time":"2013-02-27T14:22:55Z","timestamp":1361974975000},"page":"1122-1129","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Development
