Hi Candy, it is highly likely you are positive if 2 lab test have come back as reactive. Lab tests tend to look for antigens to HIV as well as antibodies however home tests tend to solely look for antibodies to the virus. I cannot comment on the test you have performed at home without knowing what test was used. Due to seroconversion the antibodies are produced at different rates depending on the individual which is why we say a negative BioSURE HIV self test can only be deemed conclusive 12 weeks post exposure. I know this is probably a difficult time for you however please remember that HIV is a treatable condition and not knowing should be the only thing that is feared. Please don't hesitate to contact me further (either on here or via email [fbard@biosure.co.uk]) if you wish to ask more questions. Kindest regards Francesca Bard, BioSure (UK) Ltd
