An evaporation line is only when the test has dried. Hence after the time frame. I took a test and had the faintest of lines.. Thinking it was a evap. I polled into this room with two possible answers to choose from. "Evap" or "vvvvvfaint" and according to so many they mostly considered it a evap. However i realized i had my result within the designated time frame. Therefore it can not be an evaporation line. It was a positive. I just want whoever is questioning if its an evaporation line that if the line appears within the time frame its a positive. Just trying to help with the heartache and headache. Baby dust!
