In order to determine whether pregnancy influences the specificity of the fluorescent treponemal antibody absorption (FTA-ABS) and Treponema palidum haemagglutination assay (TPHA) tests, these tests, together with the quantitative fluorescent treponemal antibody (FTA) and Venereal Disease Research Laboratory (VDRL) tests, were carried out simultaneously on 2000 pregnant women who attended for compulsory prenatal screening. In only one patient (0.05% of the total investigated) was a positive…

Non-specific positive test results to syphilis in dermatological diseases.
TLDR
The test producing the most non-specific results was the FTA test, followed by the FTA-ABS test, the VDRL test, and Kolmer's test; these were found more frequently in patients with pyodermas, neoplasms, acne, mycoses, crural ulceration, and psoriasis than in those with other diseases.
Fluorescent Treponemal Antibody‐Absorption (FTA‐ABS) Test
  • J. Bos
  • Biology, Medicine
    International journal of dermatology
  • 1982
TLDR
The fluorescent treponemal antibody-absorption test was developed to avoid nonspecific positive reactions in the FTA-test, which is known as the ETA-.5 test, because test sera were used at a 1/5 dilution.
Depressed CD4/CD8 Ratio in TPHA‐Negative Patients with Syphilis
TLDR
The experience with six elderly patients with syphilis, whose TPHA was negative, suggests that the TPHA is insufficient for excluding elderly syphilitics because of immunological impairment seen in aged patients.
Comparative evaluation of commercial fluorescent treponemal antibody-absorbed test kits
TLDR
The development of an immunological standard for use in the manufacture of fluorescent treponemal antibody-absorbed test kits is recommended, with the goal of obtaining uniform performance characteristics among commercial test kits.

  • G. Hart

  • 1986
TLDR
Predictive value calculations were used to derive diagnostic guidelines for syphilis and screening of asymptomatic persons with the VDRL test, followed by treponemal test confirmation on positive sera, is recommended for all pregnant women, contacts of persons with infectious syphilis, and other high-risk groups.

TLDR
Altered physiological and immunological states during pregnancy are important in understanding the pathophysiology of maternal infections.
Clinical Application Of Serological Tests For Syphilis SUMMARY
TLDR
The humoral response to T. pallidum invades the human host and multiple humoral antibodies are formed, of two types: antitreponemal antibodies and antibody-like substances known as reagin or lipoidal antibodies.

TLDR
The MHA-TP test seems to combine the simplicity and lower cost of nontreponemal tests and the sensitivity and specificity of treponemals tests, and thus enjoys features of both a screening and verification procedure, but additional clinical experience is needed before its role in the serologic diagnosis of syphilis can be conclusively determined.

TLDR
The TPHA test has proved to be more reliable than either the WR or the VDRL test, giving fewer false positive and false negative results by comparison with the FTA-ABS test.
