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).

      Chances of being coeliac

      By trents · Posted

      If this applies geographically, in the U.K., physicians will often declare a diagnosis of celiac disease based on the TTG-IGA antibody blood test alone if the score is 10x normal or greater, which your score is. There is very little chance the endoscopy/biopsy will contradict the antibody blood test.

      What was the reference range for that test? Each lab uses different reference ranges so a raw score like that makes it difficult to comment on. But it looks like a rather large number.

      I have had the tTG-IgA blood test my result are >250.0  I am waiting for the appointment with the gastroenterologist for endoscopy and biopsies.    what are the chances it’s not coeliacs.  waiting and not knowing is so hard. Especially the eating of gluten knowing it may be causing you more harm and coping with the symptoms.

      Nicotine Gum For Gluten Symptoms.. Am I Crazy?

      By knitty kitty · Posted

      @sleuth, Has your son been checked for nutritional deficiencies?  All of those symptoms can be caused by malnutrition.  I had severe malnutrition that went unrecognized by my doctors.  Intense fatigue, brain fog, depression, anxiety, and gastrointestinal distress are symptoms of deficiencies in the eight essential B vitamins, especially Thiamine B1, which becomes low first because the demand is higher when we're sick.     Celiac Disease causes inflammation and damage of the intestinal lining which inhibits absorption of essential nutrients.  Checking for nutritional deficiencies is part of proper follow up care for people with celiac disease.   Is your son taking any vitamin supplements?  Most supplements contain thiamine mononitrate which in not readily absorbed and utilized by the body.  Benfotiamine is a form of thiamine that is shown to promote intestinal healing.  Benfotiamine is available over the counter.  Benfotiamine is safe and nontoxic.   Is your son eating processed gluten-free foods?  Gluten-free processed foods are not required to be enriched with vitamins like their gluten containing counterparts.   Is your son following a low histamine diet?  Histamine is released as part of the immune response to gluten and other foods high in histamine.  High levels of histamine in the brain can cause anxiety, insomnia, and depression.  The body needs the B vitamins to make the enzyme Diamine Oxidase (DAO) to break down and clear histamine.  DAO supplements are available over the counter.  Vitamin C helps clear histamine as well.  Some people find over the counter antihistamines helpful as well, but they're not for long term use.   Nicotine has antihistamine-like properties, but can also irritate the gut.  Tobacco, from which nicotine is derived, is a nightshade (like tomatoes, potatoes, peppers and eggplant).  Nightshades contain alkaloids which affect gastrointestinal permeability, causing leaky gut syndrome.  Nicotine can cause gastrointestinal irritation and alter for the worse the microbiome. Safer alternatives to Nicotine that have antihistamine properties include Lemon Balm (Sweet Melissa),  Passion Flower, Chamomile, and Bilberry.  They can be taken as supplements, extracts, or tea.  These will help with the anxiety, insomnia and depression in a much safer way. Oolong tea is also helpful.  Oolong tea contains the amino acid L-Theanine which helps the digestive tract heal.  (L -Theanine supplements are available over the counter, if not a tea drinker.)  Tryptophan, a form of Niacin B3, also helps calm digestive symptoms.  Another amino acid, L-Lysine, can help with anxiety and depression.  I've used these for years without problems.   What ways to cope have you tried in the past?
