vs Immunodeficiency syndrome?

[Guest guest]

Hi Everyone, my son has been seeing Dr. for the last 10 months and is

taking Valtrex with no real big improvements seen, though we still do believe

his immune system is off. He never has a fever...rarely gets sick now but was

sick all the time as a toddler. I have been reading about IVIG and how it is

used for CVID (common variable immunodeficency syndrome. I wonder how is

different from CVID? Both are immune disorders? We have never seen an

immunologist and I am wondering if that is something we should look into. Would

an immunologist look at my son's blood work and see that something is off on the

immune system and try to help us treat it or is the Doctor likely to dismiss me

as a crazy mom looking for a cure?

To check for CVID, a website said they look at low levels of serum

immunoglobulins. My son has had lots of blood work done over the years and on a

test we did in 2009 for immunology AG His IgG1 was 368 with a normal range being

400-1080. The others, IgG2 IgG3 and IgG4 and Total IgG were within the normal

range.

On another test in 2010 for Immuniglobulins IgA IgM and IgG were all within

normal. The IgE was high at 382.

Would any of those tests show that he has immunodeficency syndrome or do they

show that his immune system is within the normal range (except for the first

IgG1 test)?
