Just wanted to come back and update. I got my results on Tuesday (nearly 2 weeks after the draw). I should have received them a few days earlier considering the specific lab that was doing the test said they have a pretty reliable turnaround of 8-9 days, but my Dr’s office was closed for a long holiday.
In any event, my HLA gene test results were negative. I don’t have the written report yet but the nurse should be mailing it to me. I am very relieved to finally have a clearer answer as far as true Celiac or not. Regardless, I know for absolute certainty that I am gluten intolerant. Considering all that I mentioned in my original post and the fact that it appears to me that my RA is starting to act up after my gluten challenge (bloodwork a week ago shows RF is up but CCP is still down so staying off meds for now other than Ibuprofen), I am self diagnosing NCGI and will commit myself to a strict gluten-free diet. As far as my kids, I can rest a little easier now and not have to constantly worry about whether or not they have or can develop celiac disease. On the other hand, I'm sure I'll find something else to worry about with them. For instance, I still can't explain why they are much smaller/skinnier than their peers, including their cousins whose parents are shorter/smaller than DH and I.
