TPPA, FTA-ABS, EIA, CIA) using neonatal serum are not recommended owing to passive transfer of IgG antibodies, which react with the reagents in these tests. All infants born to mothers with syphilis should
linked immuno-sorbent assay (ELISA) could be caused by hemolysis. The RPR had low sensitivity in suspected syphilis neonates, and the colloidal gold test (SYP) was suitable for emergency treatment. The treponema pallidum particle agglutination test (TPPA) was fit for the diagnosis of syphilis [...
benötigen keine wiederholten Liquoruntersuchungen. Bei HIV-infizierten Patienten kann eine persistierende Liquorpleozytose eher die Auswirkung von HIV sein als dass sie eine persistierende Neurosyphilis darstellt. Normale Liquor-Zellzahlen, negative Liquor- und Serum-Reagintestergebnisse und nega...

for syphilis, each with their own method of detecting the presence of the disease. Some of the most common types include enzyme-linked immunosorbent assays (ELISAs), rapid plasma reagin (RPR) tests, and treponemal-specific tests such as the T. pallidum particle agglutination (TPPA) test. ...
Although the CSF Venereal Disease Research Laboratory (VDRL) remains a mainstay of diagnostic testing for neurosyphilis, using a higher titer cutoff (greater than 1:320) for the Treponema pallidum particle agglutination assay (TPPA) from the CSF may improve the utility of the TPPA as a ...

However, a TPPA titer cutoff of >1:640 in the CSF has been suggested as a realistic threshold level for diagnosing neurosyphilis in highly suspicious patients who are VDRL-negative, especially if a serum treponemal test is positive.[120][129][130] ...
A test for syphilis was requested, which came back as positive for total antibodies, Immunoglobulin M, trepo- nema pallidum particle agglutination (TPPA) and rapid plasma reagent (RPR: Titre > 1:128). Full syphilis treat- ment was commenced, with an injection of long-acting benzylpenicillin as...
