This happened to me! Pre-op blood work came back positive for HIV, so I went to the infectious disease doctor, was tested again, negative this time with confirmatory testing, I even went as far as to have my 6 month old baby tested, which was negative. My doc says RA can cause false positives. I have been tested again and it was still negative. Doc says that I need to have ONLY the confirmatory test done.






I have had a false positive syphilis result in addition to the H.I.V. false positive. My doc said that it happens because R.A. is an auto immune disease and thats why it causes us to have false positive results.
