In this present study, adult worm antigen of Clonorchis sinensis and the indirect and double sandwich enzyme linked immunosorbent assay (ELISA) were used to detect the serum antibody of clonorchiasis patients from the endemic area of Miao-Li county. The results of indirect ELISA revealed a good correlation between the egg stool count and IgG strength of patients sera. Focusing on the different immunoglobulin classes in serum, the patient group has significantly higher level than that of control group, and the IgG level was distinguishly higher than the other Igs. The result also showed that the sensitivity and specificity on the detection of IgG for clonorchiasis patient were 83.23% and 100%, respectively. After praziquantel treatment, the antibody titer of patients decreased in accord with the time period, and the decrease rate of antibody titer in patients with moderate infection was more closely related to the time after treatment than those in the other degree infection groups. When double sandwich ELISA method was used to detect serum antibody to C. sinensis in patients with the different parasitic infection, it was shown that antibody levels in patients with clonorchiasis were significantly higher than those in the un-identical parasitic infection patients. Both of the sensitivity and specificity by using this method were 100%. Based on the results of the indirect and double sandwich ELISA methods, it is recommended that uses of the double sandwich ELISA incorporated with the indirect ELISA may give a sufficient results on the epidemiological study of human clonorchiasis. It may also be recommended that double sandwich ELISA method can be used for a mass survey and indirect ELISA method for further detection in the patients with clonorchiasis.
