Ive not heard of anybody getting a false positive with this one! I had a positive on one of these along with 2 or 3 very very (i mean extremely, hardly there at all) faint lines on cb dye tests, I had to take them from case and hold up to the light to see them! It turns out I had a chem pg as I went to hospital and had bloods done.
In fact I did a digi one day which was positive , the next day is was negative.
Hope this helps
