I am totally new here and don't know much of anything about Celiac. I'm hoping those of you with more experience can shed some light for me. I was diagnosed with Hashimoto's (autoimmune hypothyroid) in 2009, and recently, in January 2013, I was diagnosed as B12 deficient and low Alkaline Phosphatase (a liver enzyme). I've been on B12 shots since January. My B12 and Alkaline Phosphatase tests were repeated a couple of week ago and both were still low. Knowing that I have an autoimmune thyroid disease and that both B12 deficiency and low Alkaline Phosphatase can be caused by malabsorption, my (thankfully thorough) doc ordered some blood tests for Celiac. Here are my results:
Gliadin Ab IgA - 6 (normal range <20)
TISSUE TRANSGLUTAM AB IGA - <1 (normal range <4)
GLIADIN IGG - 5 (normal range <20)
RETICULIN AB (IGA) SCREEN - negative
I have a couple of questions. First, from the limited material I've read, the Gliadin Ab IgA and GLIADIN IGG are no longer considered the best indicators and are being replaced more and more with Gliadin (Deamidated) tests. Is this true? Also, I haven't been able to find much of any info about the Reticulin AB (IGA) screen test. How good of an indicator is it? Also, it doesn't look like they tested my total IgA, which from what I've read would show if I'm IgA deficient or not.
I don't know if I have symptoms or not. I will occasionally (once a month or so) become very bloated, with pain if I press on my abdomen. I've tried bloat medicines (such as gas-x) which provide no relief. After a day or two, the bloat goes away on its own. Also, my bowel movements are not regular. Some days I will have very loose stools (sometimes with and sometimes without the urgency of diarrhea), and sometimes I will go several days without any bowel movement at all. Sometimes I will have very solid stool, but with a very sudden urge to go (I would compare it to the urgency of diarrhea, but with solid stool). I never thought much about all of this until the doc mentioned Celiacs.
I also have still had fatigue and brain fog (which I initially assumed were related to my thyroid) even though I'm on thyroid meds and my TSH is normal.
Basically, my major question is, should I be satisfied with the blood tests above and a negative Celiac diagnosis, or should I press for additional tests? I'm so confused by everything I've read online and want to be able to properly advocate for myself, but I just don't understand most of it.
Thanks for any insight you can provide!
