I can't see the faint line in the pic, it could be the quality of the picture. Can you produce another one?

Ecupirate87, BT answered your questions in both of his above posts. A faint line is a line no matter what. I have the same test strips that you are using and they produce the same result's for me time to time, some just tend to be darker than others. Ive even used them to test my synthetic urine and they produce faint lines. You cannot judge these strips by the faintness of the line, they produce only a positive(visible line) or negative(no line) result .
