Syphilis serology in human immunodeficiency virus infection: evidence for false-negative fluorescent treponemal testing.
Injection drug users were assessed serologically for human immunodeficiency virus infection and syphilis every 6 months. Treatment histories were reviewed for any high-titer biologic false-positive (BFP) reactors, that is, persons with rapid plasma reagin (RPR) titers > or = 1:4 and negative results for fluorescent treponemal antibody absorption (FTA-ABS) tests. Selected sera were analyzed furt...
متن کاملFalse-positive reactions in the rapid plasma reagin-card, fluorescent treponemal antibody-absorbed, and hemagglutination treponemal syphilis serology tests.
Sera from 628 nonsyphilitic individuals were tested with the Rapid Plasma Reagin-Card, Fluorescent Treponemal Antibody-Absorbed, and Hemagglutination Treponemal Test for Syphilis tests to ascertain the comparative specificity of these tests. Many sera were also tested with the quantitative Venereal Disease Research Laboratory test. Sera included in the study were from both normal individuals an...
متن کاملFluorescent treponemal antibody tests on cerebrospinal fluid.
Reports of fluorescent treponemal antibody (FTA) testing of cerebrospinal fluids have appeared in the literature from time to time (Harris, Bossak, Deacon, and Bunch, 1960; Vaisman and Hamelin, 1961; Niel and Fribourg-Blanc, 1964). It has become accepted practice in our laboratory to perform an FTA test, without absorption with Reiter treponemes, on undiluted cerebrospinal fluid (CSF). As no es...
متن کاملEvaluation of the automated fluorescent treponemal antibody test for syphilis.
The Automated Fluorescent Treponemal Antibody (AFTA) procedure developed by the Space Division of Aerojet General Corporation (El Monte, California) was tested in this laboratory as part of a field evaluation sponsored by the Venereal Disease Research Laboratory of the National Communicable Disease Center, Atlanta, Georgia (Stout, Lewis, Duncan, Hunter, and Lantz, 1968). The reactivity of the a...
متن کاملSerological tests for treponemal infection in leprosy patients. An evaluation of the fluorescent treponemal antibody absorption (FTA--ABS) test.
Much has been written about the biological false positive (BFP) reaction demonstrated by reagin tests applied to sera from patients suffering from leprosy. It is well known that a BFP reaction is in all but a very small minority of cases proved or disproved by recourse to specific tests for treponemal infection, i.e. the Treponema pallidum immobilization (TPI) test and/or the fluorescent trepon...
