Hi Abigail,

My kids or family do not have coeliac's. My GF is married to a man who was diagnosed very late in life and their now daughter has quite a few symptoms of coecliac's. Such as tummy upsets.
The blood test was not accurate, it came up negative, her daughter still had tummy upsets. She then got a referral to see a Paediatric Gastroenterologist who acutally went in by doing an gastro endoscopy and had a look and confirmed what is in fact coeliac, as they caught it early, there hasn't been too much damage yet. Their daughter is 8yrs old.

HTH
