The fungus easily disseminates in persons with AIDS, resulting in progressive disseminated histoplasmosis (PDH), which can progress rapidly to death if undiagnosed. The availability of a simple, rapid method to detect<jats:italic>H. capsulatum<\/jats:italic>infection in less developed countries where the infection is endemic would dramatically decrease the time to diagnosis and treatment of PDH. We have developed an antigen-capture enzyme-linked immunosorbent assay (ELISA) to detect PDH antigenuria in infected patients. The assay uses polyclonal antibodies against<jats:italic>H. capsulatum<\/jats:italic>as both capture and detection reagents, and a standard reference curve is included to quantify antigenuria and ensure reproducibility. We evaluated this assay using specimens collected from patients with AIDS and culture-proven histoplasmosis in a Guatemalan clinic (<jats:italic>n<\/jats:italic>= 48), from healthy persons (<jats:italic>n<\/jats:italic>= 83), and from patients with other, nonhistoplasmosis diseases (<jats:italic>n<\/jats:italic>= 114). The ELISA demonstrated a sensitivity of 81% and a specificity of 95% in detecting<jats:italic>H. capsulatum<\/jats:italic>antigen in urine. This assay relies on simple technology that can be performed in institutions with limited resources. Use of this test will facilitate rapid diagnosis of PDH in countries where mortality is high, expediting treatment and likely reducing PDH-related mortality.<\/jats:p>","DOI":"10.1128\/cvi.00066-09","type":"journal-article","created":{"date-parts":[[2009,4,9]],"date-time":"2009-04-09T01:46:55Z","timestamp":1239241615000},"page":"852-858","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":55,"title":["Development
