Hello there mate! I am not sure what the Sugar test was called. They said they were sending me for a bacterial overgrowth test. I never had any blood taken, I just blew in to a tube and they were somehow checking levels. What you have to say is very interesting also. I never heard of anyone having issues digesting sugars. Do you have to watch your Sugar intake? I don't think I could handle that. Chocolate is my downfall.
