Efficiency of serodiagnosis in amebiasis. Results obtained by four different tests in 13 458 persons with varying exposure.
Results are reported of antibodies to E. histolytica antigen obtained by enzyme immunoassay, complement fixation, indirect hemagglutination and latex agglutination in sera of persons with varying exposure to infection by E. histolytica. The data are compared to findings in non-exposed persons and in patients with amebic liver abscess. From the results it is concluded that the value of serodiagnosis in amebiasis is higher in patients, who have traveled in tropical areas for a limited period, than in residents of the tropics.
