Abstract
An enzyme-linked immunosorbent assay (ELISA) for the serodiagnosis of Toxoplasma gondii infections on single serum dilutions was developed. This test system is a standardized kit designed to detect circulating specific antibodies to Toxoplasma gondii in human sera. It consists of Toxoplasma gondii soluble antigen-coated microtitration multiwell plates, specific immunoglobulin-enzyme conjugate and other required reagents. In a clinical trial performed on sera from 1,035 clinically suspected toxoplasmosis cases, the Sabin Feldman Dye Test (SFDT) and this ELISA system agreed closely. Relative to the SFDT, the sensitivity and specificity of the latter was 98.0% and 97.6% respectively with a correlation coefficient of 0.97. In a further study of 121 sera, the Indirect Fluorescent Antibody Test (IFAT), the Indirect Haemagglutination Test (IHAT) and this ELISA procedure showed over 90% agreement, with correlation coefficient of 0.98 and 0.95 respectively. Within the working concentration of specific antibody to T. gondii in human serum, there was a linear relationship between the ELISA values and the WHO international standard for human anti-Toxoplasma serum.
