Among the main methods employed are the enzyme-linked immunosorbent assay (ELISA) and the immunofluorescent assay test (IFAT). We show that two commercial assays representing the two methods with two different cut-off titres can lead to significant differences in diagnostic and seroprevalence estimates. This in turn emphasizes the need for a standardized gold method to compare the various assays; whether this standard is \u2018in-house\u2019 or commercially obtained.<\/jats:p>","DOI":"10.1017\/s0950268811000021","type":"journal-article","created":{"date-parts":[[2011,2,15]],"date-time":"2011-02-15T16:55:35Z","timestamp":1297788935000},"page":"36-41","source":"Crossref","is-referenced-by-count":23,"title":["The application of an enzyme-linked immunosorbent assay or an immunofluorescent assay test leads to different estimates of seroprevalence of<i>Coxiella burnetii<\/i>in the population"],"prefix":"10.1017","volume":"140","author":[{"given":"G.
