Brief Answer: DETAILED BELOW Detailed Answer: Hello Thanks for writing to us with your health concern. A positive VDRL does not always mean that you are having syphilis. To confirm syphilis, specific antibody test for syphilis has to be done ( FTA - ABS ). Once that is positive only you should be treated with penicillin. VDRL is only a screening test, not a confirmatory test. SO please dont worry. Age, infections, immune related conditions, non specific fever, even pregnancy itself - all these can lead to false positive results. I strongly suspect that you did not have syphilis, just had a false positive result due to some other factor. If you have a positive VDRL test this time, please have confirmatory test for syphilis, and only then proceed for treatment. ALso, get your husband treated, so that you would know the likely reason. Take care. Please feel free to ask for further clarifications.
