Accurate Food Allergy Tests?
0

8 posts in this topic

Hi everyone,

I was recently diagnosed with celiac disease, as well as other food allergies. I am new to this board, and I am thrilled with all of the information and support out there! I suspect that both of my children have issues with food allergies, and one specifically with gluten, and I am not sure which tests to request for them.

What is the most accurate gluten sensitivity test? blood/stool? (I was diagnosed originally with a stool analysis)

What is the most accurate food allergy test? One ped said blood tests were not accurate, and suggested a skin prick test, but another ped said the skin prick test was not accurate. I don't want to put my kids through unnecessary tests.

Thank you so much!

Laura

None of the food allergy tests are that accurate. You have to use the tests to guide an elimination diet. Blood is somewhat better than skin prick.

As far as gluten, it's best for them to get a celiac blood test to start. If your child is not celiac, you can look to stool or simply try eliminating gluten. Eliminating gluten from the diet and seeing a good response is actually considerably more accurate than the stool testing.

Thanks Skylark! I will try eliminating gluten to start and see what happens.

Do remember that celiac tests don't work gluten free. You'll probably want to get the celiac panel run on the child you suspect has gluten issues just to be sure it's not celiac.

Good luck and I hope you figure out the allergies/intolerances!

I have to agree with Skylark. I don't believe food allergy testing results are worth the paper they're printed on. :unsure:

Once you have eliminated gluten as the source of problems, then you should look to the other top eight allergens, which for those with gluten problems probably lead off with dairy, soy and corn. And the best way to do this is with elimination and a food and symptom diary. Much more reliable than any medical testing.

I wish it was as simple as a test, I am still battling to find what foods bother myself and my daughter. I have celiac disease and also intolerant to quite a few things. I also found they have improved slightly over time I think when you first begin the gluten-free diet you are so sensitive to anything and it takes a long time for the gut to heal.

If you are having your child tested for celiac disease, make sure your child is eating lots of gluten when testing.

You can also have the FM testing which is Hydrogen Breath Testing if you suspect Fructose is a problem.

Lactose is blood testing.

Apart from those, I think its trial and elimination.

Good luck!

Thank you for all of your responses! I will try the elimination diet, but it is tough to do with 4-year olds! I thought I could do a blood test, and find out quickly what the problems were, so as not to needlessly remove common food from their diet, but it really seems like the elimination diet is the way to go.

If your insurance covers it, you can guide the elimination test with allergy tests. Either skin or blood will pick up possible food allergies depending on what your doctor prefers. What you don't want to do is assume things that are positive in the allergy tests are actually a problem. Not all foods that show up in blood and skin tests are actually a problem.

This is an LA Times article that talks about the issue. http://tinyurl.com/26etyqt

    • Marip, Have you been diagnosed with celiac disease or Non-celiac Gluten Intolerance?  I notice you joined in 2014.  Did you ever go guten free?  How can we help?   Sorry, I'm not a stool expert!  You could Google it...  Malabsorption?  Standard lab tests that check for anemia and vitamin deficiencies, etc.  should help make that diagnosis.  
    • You can eat just a slice or two (or equivalent) of bread a day for accurate testing.   I understand about the high deductibles.  We're self-employed and we pay for our health insurance. 
    • Sure, if it's gluten free, then fine.  I am very allergic (like anaphylactic) to ibuprofen and aspirin.  So, in my case, I would just tough it out.  Go to bed.  Sleep it off.....eventually. My money is on the garlic and onions.  I can't consume those either (damn that zonulin/leaky gut -- google it along with Dr. Fasano).  I just season with salt, pepper.  Boring.  But no gut issues.  I'm hoping like my lactose intolerance (resolved), that I will get garlic and onions back.   Finally, sometimes just eating anything can hurt when you still have intestinal damage.  Hopefully, you'll feel better in two or three hours if it's celiac related.  Longer if it's an intolerance (leaky gut thing....) Hugs!      
    • I read on their website that all Advil is gluten free, I had such bad pinching cramping today(which I don't why since I prepared all my food at home today.) I made a pot roast, salt garlic, onions...No gluten but still pain, That's the only thing I ate today..I don't eat breakfast or anything.   Anyways.   Is it a good idea to take Advil for the cramping? That's how I would describe it like someone is reaching inside me and pinching me and twisting my insides.    This is what I took  
    • I'll give my PCP a call tomorrow and see what they can offer. My only worry is the expense as anymore tests will put me behind in being able to afford to see the GI. I have high deductible insurance but get money put into my HSA. I'm still trying to pay off the CT scan though. Which is why I'm trying to pick and choose which poses the greatest risk for me right now and what can wait. (Though I would prefer not to wait on any of it.)

      I really do hope its only IBS. Though I always worry IBS is more or less a doctors way of saying "I have no clue" at that point. :C

      Again, I'll be sure to give my PCP a call tomorrow then and see what the options are. I can feel a lot better trying the blood work first. however, once that is done, do I still need to be on a gluten diet before the endoscopy? Also, is it ok if I still mildly reduce the gluten. As in, can I avoid a whole wheat pasta dinner, but still be eating the peanut butter crackers? That sort of thing. Again I guess that is more of a doctor related question. I just wasn't sure if in order to raise your chance, you have to mass consume gluten or not. (Its already in just about everything to begin with.)   --Edit--
      I just now reread the part that you still need to be on the gluten foods even for biopsy so I'll be sure to do that too.
