Difference between Evap lines and Positives on BLUE DYE TESTS.

Trena

Just in case anyone was wondering or curious.

On these blue dye tests in particular, I had SIX “positive” tests. They all showed up within 3-5 minutes, but all of them looked like the evap line, and it was. I was not pregnant. Be careful, and don’t get your hopes up with these tests.

^Positive.

^evap.
