Hi extremelyworried, If your only possible exposure was 4 years ago, then your results are extremely reliable and you do not need to retest. I hope this helps. All the best, Becky

Thanks Becky. I followed up the clinic result with a Biosure home test 5 weeks after the initial POC rapid test at the clinic which was also negative. Can I safely say that I am HIV negative without further retesting as I didn't have a recent exposure as my partner and i have been together for 4 years?

Hi extremelyworried, If your last possible exposure was over 4 years ago, your negative result from the clinic should be very reliable and conclusive, meaning you would not need to retest. However, it would help to put your mind at rest, you are of course welcome to perform another test but sometimes testing following a conclusive negative result can only prolong your worries. Given the time since your possible exposure, I am fairly confident in saying that if you were to have been infected, antibodies would be present in your blood in high volumes and therefore it is likely that a test 4 years later would be able to accurately detect infection. I would recommend to try and accept your results and move on from this. If you have any other questions, please feel free to leave them below, thank you. All the best, Becky
