Hi, I had posted about a month ago and since then have had more testing done. My initial test, requested by me, was just an IgA which came back negative at 172 out of a ref range of 61-356. I then requested further testing since I was still getting no other answers and they ran the genetic typing which was positive.
So after that, they ran more testing. My doctor just called and told me that my IgA still came back normal but my IgG came back weakly positive at 25 with <20 being normal.
I'm now being referred for a biopsy. Is this typical that celiac is expressed with a pos IgG and neg IgA?
Also, I have been feeling great for the past two weeks (on a typical, gluten containing diet) so I had convinced myself that it was all just stress and this result came as kind of a shock since I've been feeling so good lately.
I'm definitely not as scared of the idea of celiac anymore, after worrying about other possibilities, but I'm just kind of perplexed as to the results.

Hi, I am brand new here and hoping that some of you might be able to help me out with what to do. So my backstory. I've never had any troubles with food growing up. I've always been slightly underweight, but so is my grandmother and I look a lot like her.
In October, I was training for a half marathon and after a ten mile run, I was just wiped out like never before and my stomach didn't feel right. Not uncommon for a long run, but it felt different. And it never went back to normal. I had days where I felt totally fine, I had days where I felt just bloated, gassy, and like my digestive system wasn't working right, and then I also had a few days that I was stuck on the couch all day, utterly exhausted with no appetite.
I had a bunch of blood draws, stool sample testing, and an X-ray of my belly. No diagnosis. I saw a chiropractor and got more X-rays with no diagnosis. I asked to be tested for celiac and the blood draw came back negative. I had finally decided that it was all just stress and was about to go in and ask about anti anxiety meds, but I decided to first try an elimination diet. I'm currently on day three of cutting gluten and dairy (mostly successful except a few very sneaky things). I'm an emotional wreck, thinking about all the possibilities and the very real idea that I may never eat those foods again or be able to eat out with friends in our small town.
I have two young boys and I'm not sure if I sold force them into a gluten-free diet or even if I should be trying that yet without a diagnosis.
Any help would be greatly appreciated and maybe get me to stop crying.

Update: here are the test results.
Immunoglobulin A, S 172. Ref range: 61-356 mg/dL

I have no idea what this means.
