Brief Answer: Hello . Welcome ! Detailed Answer: Thank you for your message . The p 24 antigen which was initially positive , is a sign of HIV virus being present. The p 24 antigen however can be falsely positive as well as the antibodies were negative . The test you did later 6 months ago have revealed everything negative so this sums up that there was a high possibility of that false positivity . A clinical co relation would also be required . I would suggest you to do all the tests again now that you have mentioned above and get back to me . Thanks and Take care
