Help me interpret candida test (IgG and IgM)

Candida spp. IgG - positive 45.49 IU/ml (higher than 12 is positive) Candida spp. IgM - negative 1.00 IU/ml

Does IgG positive only means that I used to have candida infection and now it is dormant or it means something else? My GI doctor says that everbody has some levels of intestinal candida and therefore this test does not prove anything. What do you think?
