I've been blood tested. I had an endoscopy 2 years ago and called the office to find out if they ever did the biopsy (back when I ate wheat/gluten). My blood test came back negative and I was GF at the time so I know why. I am being tested for Lyme since I had a suspect blood result pop up. But the doc did ask me to investigate celiacs again since a lot of the symptoms can be similar.
My sister is working on a celiac diagnosis too. Only she has the chronic stomach pains if she accidently eats it and I usually have some stomach pain, but more of less neurological/brain fog symptoms.
So what happens if you eat it (and have been diagnosed officially?) I'd like to help out my sister as well who really (seem to) have the textbook symptoms compared to me & she has a GI that is pretty much worthless. BUT she also doesn't want to go back on gluten to get tested bc of all the pain it will cause
