Back to square one?

So a few weeks ago we were back at the hospital meeting with Olivia's gastroentologist. We have been seeing him for over a year, he originally discovered how she is all clogged up and has had her on a laxative for over a year now. She is mostly cleared out now and has put on some weight but has hardly grown in height. I showed him her blood tests --indicating celiac disease and asked him about the biopsy my GP requested. We ended up having a conversation that went something like this.

Doctor: "Why did you even get this test done?" looking at the results....

Me: "Because Olivia's not growing and the GP was worried that progress wasn't being made."

Doctor: I hate this pathology center, they test everything correctly except celiac serontology. I am going to order a new blood test and analyse it myself and it WILL come back negative.

Me (thinking): why get a blood test if you have already decided what the outcome will be?

Doctor: If I had to do a biopsy on every positive celiac blood test I would never get to go home at 5:00

Me (thinking): well, I do pay you $400+ for one visit, you are the #1 at this posh private hospital in Sydney, so maybe a few late nights wouldn't kill you.

I finished up with him and then we went and got some more blood tests. He said he would call with the results in 3 weeks and if it was negative he would not see us again until 6 months. I figured since he already decided it would come back negative that I would start back at square one and go see an pediatric endocrinologist (dr.s who help kids grow). I haven't taken Olivia off of gluten yet, as we need her to eat it in order to get accurate tests for both her blood work and also for her biopsy. If the doctor won't do a biopsy then I might go gluten free without his consent. My grandparents sent me a book about going gluten free and Olivia fits all the typical symptoms to a T. In addition, after doing some homework, we discovered that her grandma has also tested positive for celiac disease, and her other grandma is allergic to yeast so --whether it is an allergic reaction to yeast or gluten we can hedge our bets by getting rid of the same food.

Overall, this might just be a smaller piece to the puzzle...I was kind of hoping it was the finally piece!
