I had a test at my home. Then after 20 minutes there was only control line – but after two hours a very faint lines almost unseen appeared. What does it mean? Positive or negative? Also, if rapid blood test that shows negative is stored for number of days can it change to indicate two line or positive?

Hi rapid blood test. Could you please confirm what test was used so that I am able to help you further. Most tests have a read time limit as the result could change however the BioSURE HIV self test is extremely stable and the result shouldn't change, even after a couple of months. I look forward to helping you more. Kindest regards Francesca Bard, BioSure (UK) Ltd
