I had a positive test myself but it was several years ago. Part of the expense you paid to have the test done should cover taking her back to the doctors office and letting him check out the test area. I would definitely have it looked at. It sounds like a positive test to me but then I can not see the area, can I? Just because she test positive does not necessarily mean she has the disease. An x-ray will be done to verify the results. I know this is scary but you need to know for sure and the only way to do that is to let her doctor check it out.
