Im a bit concerned. Im sure my result was negative bit there was a slight red shadow ontop of blue line on test strip. It looked like where the blood has seaped up. It wasnt where i would have expected a test line nor was it the same
colour as the control but it is still worrying me a bit.

Hi worrier3. A positive line can only appear in an exact place. The red at the bottom of the strip is simply migration of the blood sample and buffer solution. This is normal and nothing to worry about. If you would like to send me a picture to confirm this please do not hesitate to contact me further via email (firstname.lastname@example.org). I hope this helps and thank you for choosing BioSure. Kindest regards Francesca Bard, BioSure (UK) Ltd
