Comparison between standard ELISA and dot-ELISA for serodiagnosis of human trichinosis
Abstract:
The dot enzyme-linked immunosorbent assay (dot-ELISA) provided rapid and accurate detection of human trichinosis. Comparable sensitivity and specificity of the standard ELISA and dot-ELISA were obtained when sera of 18 confirmed cases of trichinosis were screened. Cross-reactivity was assayed with sera from 31 Chinese subjects with other parasitic infections. Only 2 cross-reactions occurred in the dot-ELISA, compared with 7 in the standard ELISA.
