摘要: Two rapid and simple enzyme immunoassays (EIA) for antibodies to E. histolytica the protozoa causing ambiasis, are described. In dot EIA, a qualitative procedure, antigens were dried as small (3 mm in diameter) on thin white opaque polystyrene strip serum samples assayed undiluted. The assay required 3 incubation periods, 1 minutes each, was completed 9 minutes, with positive reaction revealed blue color (precipitate) antigen negative colorless. developed is stable permanent record. Microwell quantitative Microwells. also consisted periods of 15 50 minutes. results absorbance values normalized EIA units (EU). Both tests had good reproducibility, sensitivity specificity; highly correlated other serologic tests. Their reagents can be stored more than year. could suitable physicians' office laboratories, especially developing countries.
