For now I am gluten free, soy and lactose free just to keep myself on the safe side but I still feel extremely ill and almost bedridden.
You can not be tested for celiac if you are not eating gluten. If you plan on being tested you need to start eating gluten again. At least a couple of slices of bread a day for a couple months.
You don't need a specialist to order the blood test. Your GP can do that. If those were positive then you would likely be referred to a GI for an endoscopy.
