Might want to follow up with this, preferrably with an immunologist who knows about hypogammaglobulina..You can get good doc referrals from http://www.primaryimmune.org/ if you call/email them., (they have a forum too) ...I am not familiar with pediatric ranges, they are lower than adults because once they stop getting yours from the placenta they have to start producing on their own and can have transient phases of low values, so this could come up and be nothing to worry about. Some subclasses like IgG2 may not be fully developed until after 8-10yrs.
her Immunoglobulin G was low 186 (382-1026).
She also gets sick all the time. She has had a cold/ear infection/cough/croup/runny nose thing going one since like the beginning of Oct. She seems to be getting over something then she comes down with something else. She is very pale, bags under her eyes and exshusted all the time now. She was dianosed boardline iron defeincy aneamia.
But..your DD is 50% below range, IgG2 (the most common deficiency in kids) makes up only about 20%, and she has too many symptoms to ignore..that are VERY common for immunodeficiency. You should have her total IgA count if they did celiac tests. See if that is low/ below range too, that addition would also be a indicator of a problem here. Because of her age testing will be harder, but they should check IgA, IgD, IgE, IgM and subclasses IgG1, IgG2, IgG3, IgG4.
How high are her platelets- have they just been trending up and now over range or was it a one time #? a little elevation can be chronic inflammation/anemia...alot high is NOT good. Point that out to doc when you call. How's the WBC? any low? high?
Other good info @ Jeffrey Modell Foundation / national primary immune defficiency.
the domain name looks weird but its the right place ->http://www.info4pi.org/
I'm sure i worried you ..i'm very sorry, I don't have perfect information & I don't understand these problems for young children - please keep that in mind.
