Help With Results?

Hello, I am new here. I was just tested after being gluten free for 3 months. I do feel much improvement. I'm not sure why the doctor tested me after being gluten free but here are my results:

Gliadin Ab IgA SERUM 4 < i> Units 0-19
Tissue Transglutaminase Ab IgA SERUM <2 < i> U/mL 0-3
IgA SERUM 212 mg/dL 91-414

 

My symptoms were mainly fatigue, brain fog, hand swelling, foot pain, back pain, abdominal pain and gas, constipation, menstrual irregularities. My symptoms have been wearing off and the few times I ate gluten my symptoms were just awful.
 

Also, my gliadin iga was 4 so does that mean it is still positive?

I 've been gluten free for 3 months but the doctor tested my anyway since I have still had some mild symptoms. My symptoms were very bad before going gluten free(I chose to do it without consulting the doctor, bad, I know)
Is the gliadin iga positive or negative?

If you were gluten free for three months these tests are almost useless, unfortunately. 

 

Those tests are pretty much negative.

Hopefully, someone can interpret it. I am stumped!

So, Fenrir, are you reading "i" (which is 4 in this case) should be greater than 19?

I'm so confused! hahaha

So, Fenrir, are you reading "i" (which is 4 in this case) should be greater than 19?

looks to me like the normal range is 0-19, her result is 4. the "i" looks like a product of copy and pasting from a webpage.

That's what I read too; looks all negative. tTG normal range is 0-3 and AGA (anti-gliadin antibodies) range was 0-19.

 

The SGA tests are not very good, and few doctors use them any more.  Look on page 12 of this report: Open Original Shared Link You can see the sensitivity can be as low as 17% for one AGA test, which means that 83% of celiacs would be missed.  It's specificity (perecntage of positives caused by celiac disease) is lower than the other tests too.

 

The deaminated gliadin peptides (DGP) tests have replaced them, and they are usually used for testing for gluten-free compliance.  Unfortunately, you have been gluten-free for 3 months so I would expect your AGA  (and DGP) tests to be negative.  Sometimes the tTG tests can linger high for a few months, but there is no way of knowing if you are one of those people bar doing a gluten challenge for 8-12 weeks, testing, and then going gluten-free for 3 months and testing again. 

 

The only way to know if you have celiac disease is to do the gluten challenge and retest withe the newer tests (DGP IgA and IgG, and tTG IgA and IgG).
