Depends if you are diagnosed with it or gluten intolerant.  Some information here

I have a feeling they have information on diet and what foods are available.  Good luck 🙂

Blood tests are very important to help diagnose Coeliacs. 

IgA, tTg, HLA will be the most common. 

Doctors will often also want other tests to make sure your body chemistry is ok... something that can be upset as your bowel is not allowing for absorption of all the required nutrients. 

they will almost never confirm a diagnosis without a colonoscopy...
