Women reactive with VDRL only and considered as false-positive or very early infection were 04 (1.6%) (They were reactive with VDRL test but non- reactive with FTA-ABS assay).
They were stored at 0[degrees]c in refrigerator and were used for Micro-TPHA test and RPR card test, remaining 3 cc of blood was sent to Microbiology Department for VDRL test.
His VDRL test result was positive at a 1:32 serum dilution, as was TP-PA with 4+ reactivity.
Confirmed: syphilis of any stage, a reactive serologic test for syphilis, and a reactive Venereal Disease Research Laboratory (VDRL) test in CSE Probable: syphilis of any stage, a nonreactive VDRL test in CSF, and both of the following: 1) elevated CSF protein (>40 mg/dL) or leukocyte count (> 5 cells/[mm.sup.3]) in the absence of other known causes of these abnormalities and 2) clinical symptoms or signs consistent with neurosyphilis in the absence of other known causes of these abnormalities.
As per antenatal protocol TORCH, HIV, HBsAg, VDRL test were done.
The other tests conducted by the department involve the C-reactive protein (CRP) test, Anti-streptolysin O (ASO) and VDRL tests for screening syphilis.
Serum treponema pallidum particle agglutination test positive, other syphilis relative tests such as serum toluidine red unheated serum test, rapid plasma reagin (RPR), Venereal Disease Research Laboratory (VDRL), and CSF RPR, VDRL tests were all negative.
