[Immunoenzyme analysis in the diagnosis of opisthorchiasis. I. The development of an immunoenzyme method for determining IgM antibodies to the Opisthorchis antigen].

An assay was developed to determine IgM antibodies to Opisthorchis felineus antigens for the diagnosis of acute infection. The method is based on indirect solid-phase enzyme immunoassay. Optimal conditions were elaborated for analysis and its high specificity and specifications are shown in the paper.
