Just wondering how common evap lines are on First Response in stream tests? Apparently there was about a 3hr timeframe between peeing and looking but both tests have faint positives. There was no instant line like my friend had for her other positive HPTS. She is unable to do another test for another few days.

I've only experienced evap lines from Crystal Clear strip tests and have never had an evap line from FP, even weeks later (trying to hide it from the big kids) so this has me stumped. I just want her to retest now!!!! Lol.
