A logistical challenge to seroprevalence surveys is the collection and transport of serum samples. For conducting large and repeated dengue serosurveys, dried blood spots (DBS) would allow easier sample collection, shipment, transport, and storage than standard serum collection methods. Further evidence is needed to understand how well DBS performs compared with standard serum collection methods in laboratory assays. We evaluated the detection of anti-dengue antibodies by IgG indirect ELISA when using DBS compared with sera. Specimens were collected from healthy children in Cebu, Philippines, who would be 9\u201314 years of age at the time of a mass dengue vaccination program. Using an ELISA index value cutoff of 0.9, 1,285\/1,488 (86.4%) of the DBS were seropositive and 203 (13.6%) were seronegative, compared with 1,292\/1,488 (86.8%) seropositive and 196 (13.2%) seronegative serum samples. Compared with sera, the DBS method had a 98.3% sensitivity, 92.4% specificity, 98.9% positive predictive value, and 89.2% negative predictive value. Considering the advantages in terms of sample collection, shipment, and storage, DBS sampling may be appropriate for dengue population serosurveys.<\/jats:p>","DOI":"10.4269\/ajtmh.20-0937","type":"journal-article","created":{"date-parts":[[2020,11,3]],"date-time":"2020-11-03T07:00:53Z","timestamp":1604386853000},"page":"130-135","source":"Crossref","is-referenced-by-count":17,"title":["Performance
