I'm not clear what you symptoms are. Hopefully they are not a obvious as mine were ( ignored by by various medics for over 5 decades )
The blood test for Coeliac disease is well known to give far to many false negatives
Before the test were you told that, to have a hope of the test working, you sould consume significant amounts of gluten every day for at least 6 weeks prior to the test ?
It has been suggested that even the hydrogen breath test ( "the h.pylori breath test" ) is better than the coeliac blood test.
So, it does not matter if your blood test for Coelaic disease is positive or negative
A gastroscopy ( if done by a competent person* ) will show if you are coeliac
Apart from 'free food', it does not even matter if you are coeliac or 'just' allergic to gluten. **
If you have a significant problem that you think may be due to gluten then give up eating gluten - Totally !
No cheating, no sharing of toasters, no chancing products with 'does not contain gluten as an ingredient' or 'manufactured in a factory which handles gluten'. Totally no cheating - bring your own G/F lunch to work - be very very reluctant to eat out.
( Cooking from scratch is the only way that I can manage this )
Do this for three months. Most with a gluten problem will feel a bit / much better by then ( very few take over a year )

- Dont presume that 'your' gastroscopy will be done by such a person
** - Many papers have been published which show circa 1% of the population are coelaic ( mostly undiagnosed ) and a further 2% of the population are just plain allergic to gluten.
