Hi Everyone! Haven’t posted much but am so pleased with all the info I read here. Sadly, I now join the countless others being dismissed by the medical profession in getting help for B12 def, etc. Finally got my (new) Dr. to let me test for Intrinsic Factor and will do that soon. Does anyone know what this might cost? I have a feeling my insurance won’t cover it and I’ve had all the attitude I can handle from the Dr.! I’m in the US, by the way.
