What does a positive Treponemal test mean?
What does a positive Treponemal test mean?
If positive, the results may also indicate the amount of antibody present in the sample used for testing. A positive nontreponemal test result means that a patient may have syphilis. A follow-up treponemal test is required to confirm a positive diagnosis.
What does Treponema pallidum IgG IgM reactive mean?
Since treponemal tests may remain active for life in adequately treated patients, a positive T PALLIDUM IGG + IGM [86781E] indicates exposure to syphilis and it does not indicate untreated syphilis.
What does a positive syphilis antibody test mean?
If you have these antibodies, it means you have a syphilis infection now, or you had a syphilis infection that was treated in the past. Common tests to check for syphilis antibodies include: Treponema pallidum particle agglutination assay (TP-PA) Fluorescent treponemal antibody absorption (FTA-ABS) test.
How long does Treponemal antibody stay positive?
Because the antibodies detected in treponemal tests usually remain detectable for life, even after successful treatment, the non-treponemal titer (RPR or VDRL) must be used to monitor for a re-infection with syphilis.
What causes false-positive Treponemal test?
Reactivity to a treponemal test implies infection but it does not determine whether the infection is recent or remote or whether it has been treated or not. False-positive results with this type of test can occur and may be due to other infections or other inflammatory diseases, such as systemic lupus erythematosus.
What is Treponema pallidum IgG IgM blood test?
Test Details This test can be used to complete the syphilis screening and diagnosis algorithm and to detect previous syphilis infection.
What is the normal titer for syphilis?
In order for it to be adequate the levels must change by at least 2 dilutions….so 1:16 would have to drop at least below 1:4 to show a good response to treatment. A titer that bounces from 1:2 to 1:4 would not cause concern, but if it went up by 2 steps (1:2 to 1:4 to 1:8) that would be worrisome.
