My last possible exposure was 6years back. I have no symptoms. But after 6years I have done a 4th generation CMIA antigen and antibody test which is non reactive. But while I did the test I was using corticosteroid nasal spray to treat allergic rhinitis for a continuous period of 5months. Can this corticosteroid nasal spray to treat allergic rhinitis for a continuous period of 5months cause immunosuppression and reduce the
HIV antibodies so that it cannot be detected by HIV antibody test and cause a false negative?
