By any chance alcohol intake can impact hiv test results, i was scared and stared drinking to ignore the scary thoughts. i took hiv 4th gen combo test at 28, 35, 51 days post exposure it came back as negative. can it delay the hiv ag/ab results ?

There are NO medical conditions or drugs, including alcohol, that have any effect on HIV test timing or reliability. Your HIV test results are conclusive no matter how much you drink. However, you are taking a much greater health risk from heavy alcohol intake than HIV would be! Stop if you can -- and seek professional help with it if you cannot do so on your own. Good luck.
