why do you think HIV would be a possibility?
igg of 1600 would consieder normal, even if is little higher do not mean a thing. Have you tested for hiv? Had you have posible exposure?
even though igm and igg are towards higher bit of the reference range its still OK? i wanted to be sure about that. i wanted to know if, a value can fall anwhere within the given range for it to be considered normal? what if igg was 1600, then would it be considered high or normal?
It is all normal, even little lower IGA is just ok.
