I did not think to take a picture with it broken til now, it’s two days old. The control line and “positive” line looked the same day 1 but the negative line has grayed out. Is this normal should I retest? Evap line?

Question

Answer

Retest. Taking a test apart makes it invalid

Answer

This is way too old to be looking at. If you feel the need then you can retest, but make sure it’s with a pink dye test

Answer

Throw it away and take a new one
