White line on test

[casann]

Just took asda own test which have always been reliable for me in the past and within 30 secs a very obvious white / silver line with colour around came up where the test area is. The line was definelty not there before . Does anyone know what this means ? I've seen evaportion lines and this is nothing like it .
Thank you x

I'm pretty sure it's just the antibody strip, which sucks. Mine always have a white line that ends up fading into the background and turning gray. :[
