How Much Gluten Should I Eat Before Having A Celiac Test???

A MyFoodAllergyTeam Member asked a question đź’­
Wisconsin Dells, WI

Several years ago, I was tested for celiac but was not eating any gluten at that time and my test was negative. Now my doctor wants me to redo the test and said I should eat some gluten before testing. Can anyone tell me how much or how long before tests I should start eating gluten??

I wouldn’t do it. Last time I had gluten I threw up for 9 hours and no amount of nausea medicine touched it. Thought I was going to die. I ate gluten until I was in my 20’s then all of sudden had those kind of attacks. Also heart palpitations and tachycardia, migraines, and more. The older I get the worse it gets. If you know you’re allergic just say you know. You can also get a test for the 2 celiac genes on 24&Me. It’s just spit. No eating anything or risking getting sick or having anaphylaxis.

If you suffer stomach pains when eating gluten you probably will not need an awful lot to show up on tests
