I did a test this morning with FMU and it had a load of dye run but instantly created a pink test line. The picture was taken a few hours after I took the test so has dried now and appears lighter but it was a lot darker and visibly pink at the time I took it. I was unsure how to interpret the test so I done another of the same test with the same urine and it came up practically the same with dye run but pink test line. Is this test positive or a false positive?
