output: hello welcome back to icliniq com to answer your query I want to give reference of published research that although the reported sensitivity and specificity of fourth generation tests are more than in numerous studies there are several instances of discordance between screening and confirmatory techniques liu et al aids research and therapy 2016 13 false positivity can be due to user error or cross contamination if there is ongoing some other illness eg malaria or if there is a history of blood transfusion autoimmune diseases a positive test result always needs to be routinely confirmed using a different type of test or testing kit fourth generation tests are more than 95 accurate at six weeks and this needs to be confirmed after three months with a second test if the test in your case has been performed at three months after the exposure and is giving negative results and you have not had another risk you do not have hiv your fourth generation test and ran per at and 10 weeks and further 12 weeks negative ran per suffices to rule out infection if you still have apprehension get a repeat hiv antibody test at six months of exposure no need to repeat it in between take precautions in the future consistent and correct condom usage I hope this helps
