It would be helpful if you also had a test for IgM, which shows if the infection is current.
IgG shows a past infection. If IgG is high with IgM, it means you had a past infection and still have an infection. If IgG is high without a high IgM, it means you had a past infection, but you do not have a current infection. High IgA may reflect a more superficial Candida infection on the mucosal surface, such as the lips.
Have you had the blood test for the Candida antigen? If high, it indicates the mucosal and immunological barriers have been overwhelmed with candida. My past blood tests for this have always been very high, but conventional doctors ignored it likely because they weren't taught about it in school.
