This principle is followed in many of the screening tests: mammography before biopsy for breast cancer screening; RPR before treponemal antibody tests in syphilis; and ELISA followed by Western blot for testing of HIV However, this has not been the case in cervical cancer screening since the introduction of HPV reflex testing in 2004.
The Venereal Disease Research Laboratory test result was positive (titer [greater than or equal to]640), and a fluorescent treponemal antibody absorption test result was strongly reactive.
This should include a combination of molecular analysis, fluorescent treponemal antibody absorption (FTA-abs), TPHA measurement at a higher dilution (to counter the effect of possible hypergammaglobulinaemia), total IgG, and screening for autoimmune diseases with anti-nuclear factor measurement.
e, 2-fold dilution) of normal serum to produce samples with gradually decreasing amounts of treponemal antibody.
Traditional algorithms recommend a nontreponemal assay for screening followed by a treponemal antibody test for confirmation of any initially reactive samples (Figure 2a, page 32).
Laboratory tests revealed that his erythrocyte sedimentation rate (ESR), antinuclear antibody (ANA) level, rheumatoid factor (RF) value, and fluorescent treponemal antibody absorption (FTA-ABS) titers were within normal limits.

The result of the serum fluorescent treponemal antibody (FTA) absorption test was reactive.
The 2 commonly used specific treponemal tests are Treponema pallidum hemagglutination (TPHA) and fluorescent treponemal antibody absorption (FTA-ABS).
An 18-year-old woman (gravida 1, para 0, last menstrual period September 27, 1995) presented for her first prenatal visit at 31 weeks' gestation, at which time she was reactive (1:32) for rapid plasmin reagin and had a 2+ fluorescent treponemal antibody.

Treponemal tests: Treponemal tests, including the FIA-Abs (fluorescent treponemal antibody absorption) test and syphilis immunoassays, detect antitreponemal antibodies and indicate exposure to syphilis during the patient's lifetime.
