Is two weeks without eating gluten long enough to effect a blood test?

I have myltiple family members who have been diagnosed but they are cousins/aunts. No immediate family members have benn diagnosed. But i have been having a lot of problems and it got so bad that i just gave up gluten without getting tested. I was off gluten for  16 days before taking a blood test that came back negative. Ive been eating gluten for less than a week now and all my symptoms that almost went away after 10 days of not eating gluten have come back. So im wondering if not eating gluten for the 16 days before the test may have been why i got negative test results? Or is that not long enough to impact test results?

It's possible for the numbers to come down quickly, but it's also possible you did not get the full celiac panel done. It only takes one high to warrant an endoscopy/biopsies being done by a gastroenterologist.

The full celiac panel includes:

TTG IGA
TTG IGG
DGP IGA
DGP IGG
EMA
IGA

You are supposed to be eating gluten daily for 12 weeks before the blood test.

      Draft gluten-free ciders… can they be trusted ?

      By Rogol72 · Posted

      A friend of mine is in the bar trade most of his life and has never heard of lines being mixed for different type of beers and ciders. Better to stick with cans.

      By Rejoicephd · Posted

      Thanks very much for confirming my suspicion @Scott Adams! That helps a lot because I'm really trying to track down and get rid of these sources of cross-contact and so I'm going to just rule out the draft ciders and hope that helps. Also @Rogol72 its nice to hear you haven't had a problem on that side of the pond - draft cider lines being used for cider only certainly sounds like the right way to do it, but I think that must not always be practiced over here!

      I didn't ask a doctor about this actually. I did ask several doctors a long time ago and they told me gluten has nothing to do with hashimoto's. One of them told me to do a gluten challenge to test for celiac, but at the time I was in graduate school so couldn't afford to be even more ill than I was. If you have the symptoms, I really don't advise you to do a gluten challenge. It messed me up mentally and physically for months. At the same time, I benefitted from doing the challenge in the sense that it convinced me that all my symptoms were truly from gluten - even stuff like insomnia! So now I am terrified to eat gluten, whereas before I would have a little once in a while and not notice anything dramatic.

      I am in a similar situation where I can't feasibly do a gluten challenge but have all the symptoms and I have 2 celiac genes. I'm curious if your doctor advised you to eat as if you had a diagnosis or if they were more dismissive about it.

      Negative, although I had most of the symptoms of celiac disease. I now eat as if I had a diagnosis.
