Dear Tony J, it is highly unlikely that both tests you’ve had would be incorrect, however they are within the ‘window period’ (when your body makes antibodies to HIV) and there are a small percentage that seroconvert up to 3 months after contracting the virus. To put your mind at rest it is worth having another test, whether that is a self-test (please make sure it is an approved self-test, such as BioSURE as there are a lot of rogue products out there which are highly likely to give you a false negative result) or a clinical test. It is good that you feel positive about your choices going forward. Take care and thank you for getting in touch. Kindest regards Francesca Bard, BioSure (UK) LTD
