Your anxieties are understandable. However, you can relax. What you "have read" is wrong, at least for all the standard HIV tests in use today. It is not possible to have negative antibody test results more than 3 months after catching HIV. Once positive, all tests are positive for life, including in people with "advanced stage" AIDS. And anyway, it is impossible to have "advanced" HIV infection and feel well with no symptoms.
So you have been seriously over tested; the very first negative result was all you needed for 100% confidence you don't have HIV. For sure don't have any more tests!
I hope this has helped. Best wishes.
Thank you for ur help and information it does make me feel better ive just read so much conflicting things i dont what to belive anymore.
"What to believe" should not be such a big problem if you limit your web searching to professional (or professionally moderated) websites, such as those run by health departments, CDC, an academic institutions. Sites run by and for infected people or those at risk sometimes are dominated by people with atypical experiences or high anxiety and can be very misleading. Of course not all other sites are misleading, and in general most MedHelp forums are pretty reliable -- otherwise I wouldn't be here! But still, just remember that anyone can post just about anything they want on the web; truth and scientific accurace are not requirements!
And it's always safest to ignore any report of "I know of a case", "in my case", or other claims of exceptions to the rules. I'm sure it would be easy to find invididual claims of HIV antibody tests becoming negative in advanced AIDS. Don't believe them.
