So I reviewed labs already done, and I am slightly deficient in IGA (normal IGG and IGM). My result was 75 mg/dl (range is 91 to 414.) The neuro who ordered it didn't mention it. I still am not clear on the relationship of this to my SFN. I will ask at next neuro appointment. Anyone have anything to read about this? Do you think this would be enough to get IVIG?
