 Low IgA?
What does an IgA blood level of 39 mean?
From what I understand normal is 80-350 mg/dl, but it must be <10 mg/dl for a diagnosis of Selective IgA Deficiency.
So, can IgA levels be moderately low, or is this most likely a lab error?
If it really is low, is it low enough to be experiencing symptoms?
