Will Fasting Skew Blood Test Results?

2 posts in this topic

Just wondering - my blood tests were negative and it just ocurred to me that I read somewhere about having to be ingesting gluten for blood test results to be accurate. Does this mean that one has to NOT be gluten-free for test results to be accurate, meaning you must be eating it normally or does it have something to do with fasting and not fasting for blood tests?

I was being tested for lactose intolerance which requires a minimum 12 hour fast and at the same time I was tested for celiac disease. Would the fasting make a difference with the celiac results?

Thanks for you help,

Chantalle

Hi Chantelle. You need to be on gluten for the blood test but not for the stool test at enterolabs. I don't think it matters anyways as many people test negative with a blood test due the it still being in the intestines and not in the blood. A negative test does NOT mean you don't have it. You could try the stool test from enterolabs or stay gluten-free and see how you do. Hugs, Carol B
