What To Eat Before Blood Test

I was just wondering what I should do with Ella before she's tested so that we get the most accurate results. Should this be done after fasting (first thing in the morning) or after eating gluten during the day?

I kind of want them to test her glucose levels again and I know they want her to fast for that so I suppose they would draw all the blood at the same time.

What do you all think? I'm nervous about getting an accurate reading as it is because she's still young (2 1/2 years) so I want to do this right to get the most accurate result.

Any advice would be helpful! We go tomorrow to the ped to talk about testing....

Hi Shannon,

I don't think an overnight fast would effect the celiac panel. As long as she is not on a gluten-free diet your results should be accurate.

I had my blood test after consuming a meal FULL of gluten... (but then again I didn't know I was going to be tested for Celiac when I went to the GI appt.) so, no fasting...

An overnight fast will not affect the results. You have to be off of gluten much longer then that.

If you are getting other tests done (lile glucose levels) than she may be required to fast. Fasting for 12 hours should not affect the results. I was sent to the GI doctor not knowing what would happen and he drew blood for celiac that day. My results were very positive for celiac and I don't believe that I had very much gluten if at all within 12 hours prior to the test.

How much gluten were people consuming in the days/ weeks/ months prior to being tested though?

Would eating crackers on a regular basis, and bread intermittently be enough to show a positive result?

The equivalent of 3-4 slices of bread a day for 3 months to feel fairly confident that you've got low odds of a false negative. There's no exact answer that works for everyone, as it depends on how quickly your intestines are damaged (and how much repair work is going on at the same time).

      Sainsbury's Free From White Sliced Bread - Now Egg Free - Completely Ruined It

      Thanks for this Russ, and good to see that it is fortified. I spend too much time looking for M&S gluten-free Iced Spiced Buns to have ever noticed this! That's interesting, Scott. Have manufacturers ever said why that should be the case?

      Sainsbury's Free From White Sliced Bread - Now Egg Free - Completely Ruined It

      In the USA only wheat-based breads are fortified with certain vitamins, but not gluten-free breads, thus we typically encourage celiacs to take multivitamin supplements.

      Are Lindt chocolate balls gluten free?

      Not much use to Canadians but if any British Lindt lovers are looking at this, give Marks & Spencer's Swiss Truffles a try - no barley but same taste. I'm pretty sure that in a blind tasting a coeliac would not know the difference - but then again, if you want to put this to the test, get a non-Coeliac to try this! I don't want anyone here to get glutened...

All serological markers continue to increase, and the doc who did the scope said there villous atrophy visible on the scope — but we just got the biopsy pathology report back, and all it says is, “Duodenal mucosa with patchy increased intraepithelial lymphocytes, preserved villous architecture, and patchy foveolar metaplasia,” which we are told is still inconclusive…  We will have her go gluten free again anyway, but how soon would you all test again, if at all? How valuable is an official dx in a situation like this?
