Hi Anxietyisreal, thank you for sharing your story and I wish you would've contacted BioSure sooner so that we could have helped put your mind at rest. As long as your exposure was 12 weeks before you tested then your negative result is conclusive. Given that you have tested 8 months, 13 months and around 24 months your result is conclusive and you #knowyourstatus. I would recommend not retesting as this will only prolong the acceptance of your negative result, instead I would put the incident behind you and take this as a learning curve. I hope this helps and thank you for choosing BioSure. Kindest regards Francesca Bard, BioSure (UK) Ltd
