It's my first time making a poll, so hopefully I did it correctly!
ok so I've been thinking lately...
so much of the current literature for celiac testing says that IgG tests are useful in patients who have insufficient IgA levels, but what about those of us who test positive for AGA IgG, DGP IgG and/or TTG IgG and produce sufficient levels of IgA but all of our IgA based tests are negative? What's up with that
How many people who only got positives on the IgG based tests, produced enough IgA ended up having a positive biopsy? If not a positive biopsy, what was your doctor's rationale for that positive IgG result?
Currently according to Dr. Fasano, you can be diagnosed with celiac with the 4/5 rule found on pg. 9 and 10 of this link:
1. Typical symptoms of celiac disease
2. Positivity of serum celiac disease IgA class autoantibodies at high titer
3. HLA-DQ2 and/or HLA-DQ8 genotypes
4. Celiac enteropathy found on small bowel biopsy
5. Response to gluten-free diet
#2 says it has to be IgA antibodies I know IgA antibodies are primarily found in the GI tract, but IgG antibodies are supposed to be the most abundant in the body, so shouldn't that count for something
I'm interested to hear others experiences. Thanks!
