Hi Worried male, So sorry for not getting back to you sooner. I hope you are well. If the condom was used correctly and there were no defects in the condom, then there should be no reason to worry. Your exposure was extremely low - no risk and your 2 negative BioSURE test results are reliable and conclusive. You do not need to retest. Your negative result is 99.7% accurate and is conclusive from 12 weeks post exposure. A negative result years after a possible exposure is extremely reliable as antibodies would be present in high amounts in your immune system and therefore the ability of the test to be able to detect the antibodies is greater. You can rely on your 2 neg results greatly and learn to trust your result and move on from this. I hope this helps. If you ever need reassurance, please feel free to get in contact via WhatsApp or our website live chat. Kindest regards, Becky
