Took 4 tests from the same urine, all with a faint line within 5 minutes but still with the pink dye background, the instructions state that you have to read within 5 minutes but the background has to be clear? Well within the 5 minutes they were positive with a faint line but way after 5 minutes when the background cleared it’s almost like they were negative? I’ll show some pics, not really sure to take them as positives or negatives. They are early 10MIU ones.
