Unclear question: If the vdrl test is positive, one month after exposure, it is reliable; if negative, you need to re do the test in 2-3 months. You should also be tested for hiv, hep c, gonorrhoea, chlamydia and may be more. Please consult your doctor for proper choice of investigation. ...Read more
VDRL is for syphilis: No - HIV testing is a separate test. VDRL is a test for syphilis. If you've had an exposure, you might be getting tested for multiple diseases. Hopefully your doctor explained that... It's always good to be safe -that's the best key to health. Syphilis is treatable and can be cured. HIV can be well managed with daily medicines, but can be fatal over time if not diagnosed. Hope this helps. ...Read more
False positive vdrl: The antibody against the syph treponeme produced by a patient with syphilis reacts with an extract of ox heart (diphosphatidyl glycerol). VDRL therefore detects anti-cardiolipin antibodies (IgG, IgM or IgA), visualized through foaming of the test tube fluid, or "flocculation". False positive results happen thru cross reaction of anocther glycoprotein. Can be from drugs, viruses, lupus, RA, etc. ...Read more

Go and get thoroughly tested and do not have unprotected sex. Good luck. ...Read moreSee 2 more doctor answers
Great question! : The VDRL & RPR check for Syphillus, not HIV. There are different kinds of HIV tests, ranging from identifying the subtypes, the viral load, and antibodies made against the virus. Switching gears, both the VDRL & RPR are only screening tests looking for antibodies made to either the bacteria itself, or to damages from infection. The RPR is faster: http://m.medlineplus.gov/ency/article/003515.htm ...Read more
Hello doctor, i had syphilis and i was treated and i did a vdrl test and it came weak reactive.. what does this mean??
Imm (une memory last: Your immune system may always have a small positive antibody response to the former presence of the syphilis, and the very weak reaction (via RPR) indicates past treatment was effective. If you are referring to confirmatory testing for infectivity still being positive, then it is also possible that you have been re=exposed and may need retreatment. Please be sure of which test and discuss with PCP ...Read moreSee 1 more doctor answer
