Title: Allergy blood testing.
Post by: Frosted Crunch on May 10, 2012, 10:09:17 AM
My Middle kiddo has PANDAS, and we just saw the allergist for his chronic sinus infections, ear infections, and upper respiratory infections.

he's allergic to rye grass, and Elder Tree.

This is what they want to run, anyone care to tell me what this is?


CBC with Diff, CMP, CRP, Quantitative Ig's (IgE, IgA, IgM, IgE) Pneumococcal 14 titers, HIB titers, tetanus titers, Diphtheria titers


Thanks!

I'm not sure what they all are, but it looks to me like they're looking for an explanation for all the infections since they're most likely not due to severe seasonal allergies.

CBC = complete blood count

The quantitative Ig's are most likely looking for deficiencies.  I know chronic infections can be caused by IgA deficiency, no sure whether IgM deficiencies can do that, also.  Elevated IgE would indicate high allergic response going on which might prompt them to seek further allergy testing.

The titers are checking for immunity to HIB, tetanus and diptheria - either from exposure or vaccines.  If your child has been vaccinated, but the titers do not show immunity, then that would also indicate the possibility of a depressed immune system.

Diff - differential. I'm pretty sure it's where they do a manual count/look-see at the various cells to make sure there's no one type of cell that's elevated, like eosinophils. (sp?)

My son had quantitative Ig panel done as part of a research study we were in years ago. Interestingly, kids with MFA can have very high overall Ig numbers.
