We tested two portable microscopic devices for the diagnosis of helminth infections in a cross-sectional survey in rural C\u00f4te d'Ivoire. We examined 164 stool samples under a light microscope and then re-examined with a commercial portable light microscope and an experimental mobile phone microscope for the diagnosis of <jats:italic>Schistosoma mansoni<\/jats:italic> and soil-transmitted helminths. Additionally, 180 filtered urine samples were examined by standard microscopy and compared with the portable light microscope for detection of <jats:italic>Schistosoma haematobium<\/jats:italic> eggs. Conventional microscopy was considered the diagnostic reference standard. For <jats:italic>S. mansoni, S. haematobium<\/jats:italic> and <jats:italic>Trichuris trichiura<\/jats:italic>, the portable light microscope showed sensitivities of 84\u00b78%, 78\u00b76% and 81\u00b75%, respectively, and specificities of 85\u00b77%, 91\u00b70% and 93\u00b70%, respectively. For <jats:italic>S. mansoni<\/jats:italic> and <jats:italic>T. trichiura<\/jats:italic>, we found sensitivities for the mobile phone microscope of 68\u00b72% and 30\u00b78%, respectively, and specificities of 64\u00b73% and 71\u00b70%, respectively. We conclude that the portable light microscope has sufficient diagnostic yield for <jats:italic>Schistosoma<\/jats:italic> and <jats:italic>T. trichiura<\/jats:italic> infections, while the mobile phone microscope has only modest sensitivity in its current experimental set-up. Development of portable diagnostic technologies that can be used at point-of-sample collection will enhance diagnostic coverage in clinical and epidemiological settings.<\/jats:p>","DOI":"10.1017\/s0031182014000432","type":"journal-article","created":{"date-parts":[[2014,4,28]],"date-time":"2014-04-28T08:47:35Z","timestamp":1398674855000},"page":"1811-1818","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":31,"title":["Evaluation of portable microscopic devices for the diagnosis of <i>Schistosoma<\/i> and soil-transmitted helminth infection"],"prefix":"10.1017","volume":"141","author":[{"given":"ISAAC I.","family":"BOGOCH","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JEAN T.","family":"COULIBALY","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JASON R.","family":"ANDREWS","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BENJAMIN","family":"SPEICH","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JENNIFER","family":"KEISER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
