Help, evap?
I took this test earlier and it was negative after the 3 mins, but a few hours later there’s a clear thin blue line. I’m sure it’s an evap but I’m confused as I thought they were colourless?!

This happened to me before red dye tests don’t do this blue dye are known for this x
I would definitely suggest red dye it's more accurate
I would retest

If it’s hours later, it’s not a good read. Take a fresh test tomorrow morning.
