If off gluten for several months, possible to diagnose with blood test?!
Question: a friend has her whole family off of gluten for quite a while. i told her i got blood tests for gluten intolerance and she's intererested, had never heard of them. how much gluten would they need to ingest or for how long for the test to have a good chance of being valid. one of the kids is autistic, which is commonly linked to gluten intolerance. he seems to be the most irritated by gluten with belly aches, etc.

You need to eat gluten for at least 2 weeks before having the blood test. You can have the test for celiacs disease (which means you cannot eat gluten as it poisons your intestines) and you can also have another test which tells you whether you have celiacs disease in your genes, which means you're most likely to be gluten intolerant.
My mum has celiacs disease and I have celiacs in my genes (meaning I'm intolerant and I could pass it onto my children and develop celiacs later in life).
My Mum went to have her endoscopy, but had been off gluten for a month. They told her to go away and come back in 2 weeks after resuming a normal diet. The test could give a false positive otherwise.
You don't need to stuff yourself with bread and etc, just resume a normal diet. Remind your friend that she and her family may need fiber supplements because removing gluten can reduce the intake of fiber.

My Grandpa has gluten intolerance and it nearly killed him before they discovered what it was. Luckily is better known now. From what I understand it is in the genes, so even if you had never had gluten it should still show up with a blood test, or a buccal swab.
