She needs to go to a doctor or planned parenthood. The pregnancy tests are obviously not accurate in her case. The only was to be 100% sure, is from an official blood test or whatever they give you.
Pretty much ditto what Rachel said. Also, I have to say that my first pregnancy test was positive and my physician pregnancy test proved the same thing. They're more accurate than they are not (if that makes sense).
Still, head to the nearest Planned Parenthood unless you want to involve her parent's medical insurance.
