false positive?

If this was mine I would assume it’s positive but I would also retest, but I’ve always been the type of person to test a million times

Try a red dye, they are more reliable. It is thick so it seems like it’s a faint positive, but blue dye sometimes gives evaps that are colored.

@Ali red dye

@amy yeah. Like a first response or easy@home. Clear blue also does make a red dye option 😊
