ok yall i took a standard test yesterday and it turned red on the end where you dip it but when it went to the results it just had one line. anyone know what it is? I've asked someone at my local health department and she said it could be ink malfunction or a very high positive for it to turn red before it even got to the results line. has anyone else had this happen or know what it may be?
