METHOD We tested 995 subjects of a rural population of all ages in the south of Bolivia, 459 pregnant women of the same population and 1030 urban women giving birth from the east of Bolivia. RESULTS The sensitivity of the CSP test for the entire studied population (n = 2484) was 94.73% [93.35-96.10]; the specificity was 97.33% [96.50-98.15]. However, the specificity differed significantly between rural pregnant and urban birthing women, which could be attributed either to differences of parasite strain or Chagas prevalence. CONCLUSION The test is simple of use, reliable, relatively inexpensive(< 2 US$ each test) and its performances are compatible with a field use for large-scale screenings. specialized Chagas' disease Trypanosoma cruzi diagnosis test screening Bolivia 052 14 7 732-735 2009 1360-2276 https://www.documentation.ird.fr/hor/fdi:010046249 10.1111/j.1365-3156.2009.02288.x 1360-2276 [F B010046249] https://www.documentation.ird.fr/hor/fdi:010046249 https://www.documentation.ird.fr/intranet/publi/2009/08/010046249.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-09-01 2017-08-23 fdi:010046249 fre
