ABSTRACT
ObjectiveTo evaluate the app li cation value of the Dipstick Dye Immuno assay (DDIA) for screening chemotherapy targets of schistosomiasis in a lower endemic area. Methods[ WT5”BZ]In a lower endemic area of schistosomiasis a random sample of 463 individuals from a natural village were examined using miracidium hatching metho d, Kato Katz's method, DDIA, DGS COPT and ELISA. The positive rates of these a ss ays were compared. ResultsThe positive rate of stool examination was 3.9% in 463 individuals. The positive rate of DDIA was 15 8%. The positive rate in 18 stool positive subjects was 94 4% with Youden In dex 0 81. The positive rate of DGS COPT was 8 9% . The positive rate in 18 stool po sitive subjects was 72 2% with Youden Index 0 66. The positive rate of ELISA w as 18 4%. The positive rate in 18 stool positive subjects was 83 3% with Youden In dex 0 68. ConclusionDDIA was more suitable for application in screening target population in lower endemic areas than other im munoassys.
