How Long After Eating Gluten Are The Blood Tests Accurate?

I'm about 95% sure I have celiac disease due to severe symptoms I have tested using my own dietary tests.

However, I haven't eaten gluten in about a month and I'm interested in getting a blood test to have an "official" diagnosis mainly for my parents and others who need that kind of diagnosis to feel that it is real.

Will a blood test such as the TTG and EMA be accurate even if I haven't eaten gluten in a month?

You could possibly get a false negative. Here's a link from this website:

This says the blood tests should go negative in 3-6 months, but I have heard of them going negative sooner. And it is still possible for you to have Celiac even if your blood tests come back negative!

      Newly Diagnosed

      By trents · Posted

      Welcome to the forum, @NCalvo822! Ditto to what Scott said. But let me ask you, what method or methods did your physician use to diagnose you as having celiac disease? Normally, it is a two step process. The first step involves a blood test that looks for certain antibodies produced by celiac disease. The second step involves an upper GI scoping and biopsy of the small bowel lining to check for the damage to the lining typically caused by celiac disease. This second step is used as confirmation of the blood work when the antibody testing turns up some positives. Occasionally, positive antibody tests scores can be caused by things besides celiac disease. Which of these were done or did you have both done before the doc declared you to have celiac disease?

      Thanks for sharing this info! Frustrating to see companies who haven't used wheat as an ingredient start to do so! https://blistex.com/product/five-star-lip-protection/

      Frustrated

      I followed the Autoimmune Protocol Diet to get my symptoms calmed down and my nutrients up.   I know what a struggle it is.  You're why I'm here. Smoothing out some rough parts of your journey makes my journey worthwhile. Here's the tests you can get for Celiac antibodies...

      This Roller Coaster Ride Needs to Stop

      By knitty kitty · Posted

      @Ginger38, I'm with you!   I could not take Metformin.  I got so sick, constant diarrhea, abdominal cramps, extreme highs and lows, no energy, weight loss, muscle wasting.  Just horrible.   Metformin is known to block thiamine absorption.  Talk to your doctor about thiamine deficiency.  It's called Gastrointestinal Beriberi.  My doctor didn't recognize thiamine deficiency outside of alcoholism.  So I took over the counter Thiamine in the form Tetrahydrofurfuryl Disulfide and felt health improvement within an hour.  Magical!   I followed the Autoimmune Protocol diet to get my stomach calmed down and control my blood glucose levels without medication. Being diabetic, we lose more thiamine through our kidneys, and the Metformin on top of it and malabsorption from Celiac.  Talk to your doctor soon!
