Thank you for your response. This is all I have and yes I meant IgA I was reading up on deficiency and wondered if the level of 0.5 showed deficiency and if I should ask for alternative investigations
The web is full of information but I am not a doctor and I really can't find the answer.
My IgG level was negative but my LgA was 0.5 U/ml
What does this mean?
Thanks in advance
