Until recently, the tuberculin skin test (TST) was the only diagnostic test available for <jats:italic>Mycobacterium tuberculosis<\/jats:italic> infection. A new enzyme-linked immunosorbent assay test, the QuantiFERON-TB Gold (QFT-G) test, was recommended by the US Centers for Disease Control and Prevention as an alternative test for the diagnosis of LTBI in HCWs. The purpose of our study was to compare the TST and the QFT-G test in Spanish HCWs in order to improve procedures for the detection of LTBI.<\/jats:p><\/jats:sec><jats:sec id=\"S019594170003753X_abs2\"><jats:title>Methods.<\/jats:title><jats:p>A cross-sectional study with blinded comparison of TST and QFT-G test results was carried out among 134 HCWs at an 800-bed Spanish university hospital. The level of interferon-7 production stimulated by the QFT-G test was measured. A concentration of at least 0.35 IU\/mL was considered a positive result. An induration of at least 5 mm in non-BCG-vaccinated or at least 15 mm in BCG-vaccinated HCWs for the TST was considered positive.<\/jats:p><\/jats:sec><jats:sec id=\"S019594170003753X_abs3\"><jats:title>Results.<\/jats:title><jats:p>Of the 134 HCWs included (mean age, 33.4 years; 101 [75.4%] women; 47 [35.1%] BCG vaccinated), the LTBI prevalence diagnosed with any test was 11.2% (95% confidence interval, 6.6%-18.1%), with the TST was 8.96%, and with the QFT-G test was 5.97% (nonsignificant differences). The QFT-G test value was higher in subjects with TST induration of at least 15 mm than in subjects with TST induration of less than 15 mm (<jats:italic>P<\/jats:italic> &lt; .001). Overall agreement between the results of the two tests was found in 94% of HCWs (K = 0.56), but agreement was only 59% in HCWs who had a positive result for both tests. Disagreement was present in the results found for 5% of HCWs.<\/jats:p><\/jats:sec><jats:sec id=\"S019594170003753X_abs4\"><jats:title>Conclusions.<\/jats:title><jats:p>Few studies have compared both tests in populations with high <jats:italic>M. tuberculosis<\/jats:italic> exposure but low BCG vaccination prevalence. Agreement between both tests is high, especially among negative Results. Studies are needed to clarify the reasons for disagreement and to establish the best TST and QFT-G test cutoff point.<\/jats:p><\/jats:sec>","DOI":"10.1086\/598519","type":"journal-article","created":{"date-parts":[[2009,7,17]],"date-time":"2009-07-17T16:16:59Z","timestamp":1247847419000},"page":"876-883","source":"Crossref","is-referenced-by-count":25,"title":["Screening for Tuberculosis Infection in Spanish Healthcare Workers Comparison of the QuantiFERON-TB Gold In-Tube Test with the Tuberculin Skin Test"],"prefix":"10.1017","volume":"30","author":[{"given":"Eva Elisa","family":"\u00c0lvarez-Le\u00f3n","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Espinosa-Vega","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c9vora","family":"Santana-Rodr\u00edguez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jes\u00fas M.","family":"Molina-Cabrillana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Luis","family":"P\u00e9rez-Arellano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Antonio","family":"Caminero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Serrano-Aguilar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2015,1,2]]},"reference":[{"key":"S019594170003753X_ref031","doi-asserted-by":"publisher","DOI":"10.1016\/j.tube.2007.11.009"},{"key":"S019594170003753X_ref025","doi-asserted-by":"publisher","DOI":"10.1001\/jama.293.22.2756"},{"key":"S019594170003753X_ref007","first-page":"1","article-title":"Guidelines for preventing the transmission of Mycobacterium tuberculosis in health-care settings, 2005","volume":"54","year":"2005","journal-title":"MMWR Recomm Rep"},{"key":"S019594170003753X_ref002","doi-asserted-by":"publisher","DOI":"10.4321\/S1137-66272005000200014"},{"key":"S019594170003753X_ref028","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200701-024ED"},{"key":"S019594170003753X_ref013","article-title":"Targeted tuberculin testing and treatment of latent tuberculosis infection","volume":"161","year":"2000","journal-title":"Am J Respir Crit Care Med"},{"key":"S019594170003753X_ref006","doi-asserted-by":"publisher","DOI":"10.1586\/14737159.6.3.413"},{"key":"S019594170003753X_ref029","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0001850"},{"key":"S019594170003753X_ref016","doi-asserted-by":"publisher","DOI":"10.1086\/503145"},{"key":"S019594170003753X_ref026","doi-asserted-by":"publisher","DOI":"10.1086\/509327"},{"key":"S019594170003753X_ref019","first-page":"513","article-title":"Prevalence and risk factors for latent tuberculosis infection among health care workers in Georgia","volume":"12","author":"Mirtskhulava","year":"2008","journal-title":"Int J Tuberc Lung Dis"},{"key":"S019594170003753X_ref017","doi-asserted-by":"publisher","DOI":"10.1001\/jama.293.22.2746"},{"key":"S019594170003753X_ref009","unstructured":"National Collaborating Centre for Chronic Conditions.
