The test you had for "glucose" could only of been a HgbA1c for that result and reference range. It reflects a level of glucose metabolism over 60 to 90 days.
I would be interested in knowing what your pituitary hormones are. TSH is one of those and without further information of the reference range or medications I couldn't say if that number is good or bad. TSH is often the first pituitary hormone to show dysfunction but it does not rule out a pituitary problem. Adrenal dysfunction could also explain some of your symptoms.
Some of the tests you mention are for screening. In other words most people with a problem will show changes reflected by those tests but not all. With continued significant symptoms, there should be deeper investigation into several areas.
A number of autoimmune conditions are associated with celiac. These are called comorbidities. There is also the possibility of a condition not usually associated with celiac.
The important factor is that you are still sick. Even though recovery after removing gluten can take some time and accidental glutening can happen, there should be a trend toward improvement. You should be asking about expectations or prognosis. You may have significant damage that will take time to overcome but unless there has been irreparable damage or there is another problem yet to be identified, improvement should continue.
Start by asking your doctor more questions about your specific situation and try to understand exactly where you are medically. That should give you a point from which to learn and understand. This can help you but can also help your doctor. Sometimes when a patient asks this question the doctor has to step back and look at the big picture in order to answer. When they do, they often see things otherwise overlooked or unnoticed.
