Sensitivity and specificity of the two assays were calculated using a patch test as a reference method. Methods: 34 patients were patch-tested for gold sodium thiosulfate, palladium chloride and nickel sulfate, and the lymphocyte proliferation to these metals was tested in vitro using mononuclear cells from peripheral blood. Results: No significant differences regarding sensitivity and specificity were found between MELISA and conventional LTT. The sensitivity varied between 55 and 95% and the specificity between 17 and 79%. Conclusions: The low specificity of the two in vitro assays suggests that they are not useful for diagnosis of contact allergy to the metals gold, palladium and nickel, since a large number of false-positive results will be obtained.<\/jats:p>","DOI":"10.1159\/000237456","type":"journal-article","created":{"date-parts":[[2009,9,4]],"date-time":"2009-09-04T09:04:16Z","timestamp":1252055056000},"page":"212-217","source":"Crossref","is-referenced-by-count":81,"title":["In vitro Lymphocyte Proliferation as Compared to Patch Test Using Gold, Palladium and Nickel"],"prefix":"10.1159","author":[{"given":"Karin","family":"Cederbrant","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Per","family":"Hultman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan A.","family":"Marcusson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lita","family":"Tibbling","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,9,4]]},"container-title":["International Archives of Allergy and Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/237456","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000237456","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T13:32:02Z","timestamp":1777642322000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000237456"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000237456","archive":["Portico"],"relation":{},"ISSN":["1018-2438","1423-0097"],"issn-type":[{"value":"1018-2438","type":"print"},{"value":"1423-0097","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,9,4]]}}}
