Scratch/prick Skin Testing?

I know this isn't really Celiac disease related, but my doctor wants to rule out food allergies based on my symptoms so I'm scheduled to have skin allergy testing done in a little over a week. Do I have to eat gluten to get this test done?

also, i take antihistamines a few times a week to help out with symptoms. i know i'm supposed to not take these before the test to avoid false negative results, but how soon do i need to stop? i took two benadryl last night after eating out to help with itchy throat and stuffy nose. do i need to push back the testing or is a week long enough?

and lastly, is putting flour on a scratch the same thing as this test? i've gotten flour on a scratch whilst baking and had no hives or unusual itchiness. does that mean i'm not allergic to wheat or what?

thanks so much!

Hi :)

It doesn't matter if you are eating gluten or not for the skin testing. However, I do remember that there was a period of time that my allergist's office instructed me to stop taking antihistamines before the test. It was over two years ago, and I don't remember how long it was.

I would suggest calling your allergist on Monday morning and asking them because it could affect the ability to get an accurate result.

It's hard to tell if your allergic or not--and to what degree, if any--from getting flour on a scratch.

thanks so much for responding so quickly! i know i'm probably being really dumb, but i thought that's basically what the test was going to be... putting small amounts of different foods on my skin and then making scratches. wouldn't the flour be the same thing?

I had allergy testing done a few months ago. I was told to stop taking my allergy meds two weeks before my appointment. I had the scratch testing done too. They used oils of the foods on tack looking things and poked my skin. I'm not sure why it's called "scratch" because it's not really scratching. It's poking.

from my understanding, this is a test to see your immune response to foods. i had it done a few months ago, and came back negative for everything. my doctor said that this didn't rule out celiac disease, since it's not an ALLERGY. nor did it rule out lactose intolerance, or any "sensitivities" i might have. it just checked for any allergic response my body might have to foods. so i don't think eating gluten before would affect it.

      Being a burden to family/friends

      Being a burden to family/friends

      By CatS · Posted

      I understand your frustration about socializing while having celiac disease. I also have allergies to nuts, dairy, all forms of gluten including oats, strawberries and MSG. I get anxiety while grocery shopping and really take my time to read all labels. I always carry a magnifying glass with me wherever I go to read labels. Many products are labelled Gluten Free but contain Oats, and apparently this is becoming more common. I almost bought some gluten free flour but read that it contained oats. A certain percentage of Celiacs have this complication. I can’t help feeling offended and excluded when others act like I am being “high maintenance”. I am becoming better at being an advocate for myself.  I have had diverticulitis 3 times and each time hospitalized-once, the attending nurse didn’t know what celiac means-she had to research...  If others around me make comments I try to enlighten them, those who don’t get it are not my friends anymore. Be very careful about cross-contamination. I was sick recently for 10 days after a meal was contaminated while I was on holiday. If servers say they have gluten free buns or bread, ask if they use a toaster specifically reserved for gluten-free, or don’t chance it. On a positive note, I didn’t find out I had Celiac Disease until I was 60. Eating a gluten free diet means no more terrible headaches, hives, rashes, intestinal bloating and irregularity, Gastro Intestinal Reflux….when I follow a strict diet and mostly always eat at home, I feel great! I also weeded out “friends” who weren’t worth being around.

      Delayed reaction

      By Scott Adams · Posted

      I agree with @trents, it's not typical for gluten exposure to cause symptoms as delayed as a week or two after ingestion. In most cases, reactions to gluten occur within hours to a few days, depending on individual sensitivity and how much gluten was consumed. The delayed symptoms you describe—stomach cramping in the mornings and flaky stool—might suggest that something else is contributing to your discomfort. Cross-contamination is a common challenge, especially when dining out, and it's great that you're doing your best to stay gluten-free. However, the inconsistency of your symptoms and the long delay between exposure and reaction could warrant further investigation. It's possible that another gastrointestinal condition, such as IBS, a food intolerance, or a reaction to something else in your diet, might be contributing to your symptoms. You might consider keeping a detailed food and symptom diary to identify potential patterns or triggers. Additionally, consulting your gastroenterologist could provide clarity. They may suggest testing to rule out other issues, such as small intestinal bacterial overgrowth (SIBO), microscopic colitis, or other sensitivities. If you suspect cross-contamination is a significant issue, you could also ask for follow-up bloodwork (e.g., tTG-IgA) to check if your antibodies are elevated, which might indicate ongoing gluten exposure.
