Printed in u.s.a. automation of the fluorescent treponemal antibody- absorption testThe feasibility of automating the decision-making tasks of the human observer in the microscopic determination of Fluorescent Treponemal Antibody-Absorption test results was investigated....
Specificity, sensitivity, and reproducibility among the fluorescent treponemal antibody-absorption test, the microhemagglutination assay for treponema pallidum antibodies, and the hemagglutination treponemal test for syphilis.Using 920 sera, we compared the specificity and reproducibility of the hemagglutination treponemal test for syphilis with those of the fluorescent treponemal antibody-absorption test and the microhemagglutination assay for Treponema pallidum antibodies; we found all three tests to be comparable....
Problems affecting performance of the fluorescent treponemal antibody-absorption test for syphilis.Immunofluorescent staining of Treponema pallidum was studied to clarify the effect of three factors on the results of the fluorescent treponemal antibody-absorption test: (i) heat inactivation of sera at 56 degrees C for 30 min before testing, (ii) use of multicircle slides, and (iii) tungsten illumination...
Immunoglobulin specificity for the fluorescent treponemal antibody-absorption test conjugate.... A class-specific anti-human immunoglobulin G conjugate is recommended to replace the present fluorescent treponemal antibody-absorption test conjugate....
