The fluorescent treponemal antibody absorption (FTA-ABS) test is a diagnostic test for syphilis.Using antibodies specific for the Treponema pallidum species, such tests would be assumed to be more specific than non-treponemal testing such as VDRL but have been shown repeatedly to be sensitive but not specific for the diagnosis of neurosyphilis in cerebrospinal fluid (CSF).
There are a number of treponemal-specific tests such as the fluorescent treponemal antibody-absorption test, T. pallidum hemagglutination assays , and the microhemagglutination assay . [citation needed] The MHA-TP is used to confirm a syphilis infection after another method tests positive for the syphilis bacteria.
The Treponemal antibody test (specific test) confirms with FTA-ABS (Fluorescent treponemal antibody-absorption). [13] Brain imaging and MRI scans may be used when diagnosing patients; however, they do not prove to be as effective as specific tests.
In contrast, treponemal tests look for antibodies that are a direct result of the infection thus, anti-treponeme IgG, IgM and to a lesser degree IgA. Nontreponemal tests are screening tests, very rapid and relatively simple, but need to be confirmed by treponemal tests. [1]
It was the woman's mission to find the Dachshund a home before the holidays. And what better way to do so than by sharing a video of the dog in his kennel and giving him an introduction to the ...
Because of the possibility of false positives with nontreponemal tests, confirmation is required with a treponemal test, such as Treponema pallidum particle agglutination assay (TPHA) or fluorescent treponemal antibody absorption test (FTA-Abs). [3] Treponemal antibody tests usually become positive two to five weeks after the initial infection ...
