Positive deamidated gliadin iga but negative everything else..???

[Happy families]

Why would I be positive to deamidated gliadin iga but my ttg iga and ttg igg and deamidated gliadin igg r below the normal range. 

All are meant to be less than 15 u/mg and I am 17.

I'm confused cause my gastro Dr is fairly arrogant and doesn't think it's necessary to do any more investigation. I have ferreting below 30 so have iron infusion every couple years. And very fatigue and often constipated and bloated.  

Am I being silly?

It would be great if you can share your results here, including the reference ranges, as each lab is different. From what you've described, you have a positive blood test for celiac disease, and this could explain your low iron issue. It only takes one positive test to be diagnosed, but the normal procedure would be to schedule an endoscopy to confirm your diagnosis (and you would need to keep eating gluten until that test was finished).

sorry i should have attached earlier. No. 1 was 6 weeks ago and no. 2 was last week. its only just above the range. Have been doing a gluten challenge in the last 6 weeks.

Can you get a second opinion from another gastroenterologist?  Your second test is also positive on deamidated Gliadin IgG, so two positives.

Some people with celiac disease are positive on all four tests (me), some are only positive on one.
