Shelf life of fluorescent treponemal antibody-absorption test reagents.
Properly prepared, standarized, and stored fluorescent treponemal antibody-absorption (FTA-ABS) reagents have been shown to have stabilities equal to other biological reagents. A liquid antigen over 10 years old has been shown to give a satisfactory reaction. Newer preparations have now been shown to be stable for over 5 years, and the tests on each are being continued. The very new liquid anti...
متن کاملFluorescent treponemal antibody absorption double-staining test evaluation.
The fluorescent treponemal antibody absorption (FTA-ABS) double-staining (DS) test has been developed for microscopes equipped with incident illumination, and the procedure offers many advantages over the FTA-ABS test when tests are performed with this equipment. In this study, 346 fresh sera, including 35 from patients with syphilis, were evaluated by the FTA-ABS DS test. Parameters for invest...
متن کاملFluorescent treponemal antibody absorption (FTA-ABS) test in yaws.
The pathogenic treponemes, T. pertenue and T. pallidum, produce similar antibodies in the serum of a person infected with either organism. Thus sera from patients with yaws react similarly to sera from syphilitic patients in the conventional tests for syphilis and in the Treponema pallidum immobilization (TPI) test. The most recent test developed for the detection of syphilis is the fluorescent...
متن کاملFluorescent treponemal antibody inhibition test.
The fluorescent treponemal antibody (FTA-200) test has been shown to detect at least two types of antibody in syphilitic serum; one of these, which can be removed by absorption with Reiter treponemes, is thought to be a group antibody which reacts with an antigen shared by Treponema pallidum and other treponemes (Deacon and Hunter, 1962). A second antibody, which remains after such an absorptio...
متن کاملFluorescent treponemal antibody test; a preliminary report.
The fluorescent treponemal antibody (F.T.A.) test described by Deacon, Falcone, and Harris (1957) was one of the procedures using treponemal antigens chosen for inclusion in the Serology Evaluation and Research Assembly (S.E.R.A.) Study carried out under the auspices of the United States Public Health Service in 1956-57 (U.S.P.H.S. Report, 1959). The test was shown to give very sensitive and sp...
