Blood Test For Food Intolerances

I have a doctor's appt. tomorrow afternoon and would like your suggestions. I know I must have other food intolerances since I am still having D every day (mostly a.m.) even though I've been gluten free for 3 months. As far as I know, I am very compliant with the diet and except for being tired and having D, I actually feel pretty good (I know it's still early in the game and don't expect complete recovery over night).

My Dr. isn't familiar with any blood tests to check for food intolerances...I'm sure I've read here that there is an ELISA test of some sort and would like to get my hands on some info I could print out and show him. He is a D.O., which is to my advantage and following my positive celiac blood panel, he told me I had celiac in Jan. at which point I asked for a referral to a GI doc and had an EGD/biopsy in April (also positive).

Thanks in advance! I know this is a great place to come for info. biggrin.gif

I had one recently and it was called a RAST test. I asked if it was the same or similar to the ELISA and the doc said yes. Doc took 5 vials of blood and is testing about 80 foods. Haven't gotten the results yet. I've been on a low fructose diet in addition to being gluten, dairy and soy free. I hope the results don't come back with too many positives because the list of foods I can eat is already shrinking.

Thanks, Kayo! I'll ask my Dr. about the RAST test although I doubt I'll get anywhere. Will be anxious to hear the results of your test...hope it doesn't show up too much.

I am going to ask him for a blood test to check for malabsorption since I've had D every day except for a few short days following my EGD on April 9. Well, that is, except today. No D. It's like taking in my car that makes a strange noise or problem, except when I pull into the auto repair shop and it does nothing. lol blink.gif

I figure I'm lactose intolerant and have been buying Lactaid milk. Lactaid tablets do nothing for me if I eat dairy. I did have butter yesterday although it's probably low-lactose to begin with compared to milk, cheese, ice cream or other dairy products. Such a puzzle! I didn't realize I'd miss cheese so much!

Maybe I'll have to just make a big pot of chicken-rice soup and eat it for a week straight and then start reintroducing foods one by one to see if I can pinpoint what's bothering me.

YES, there are several versions of the ELISA (enzyme linked immunosuppressant assay) blood test for IgE and IgG antibody mediated food allergies. I took the 100 commonly eaten food version, the vegetarian (15) food version and the herb and spice version, which 4 of my 7 food allergies. Enterolab's stool tests, for gluten, casein, soy, egg and yeast, diagnosed my other 3 allergies (gluten, casein and soy). US Biotek lab (in Seattle) offers and processes ELISA test samples.

      For people with celiac disease and corn intolerance from it: Is salt still okay for most people?

      By trents · Posted

      Gluten-like cross reactions to other foods are from the proteins that make them up. Dextrose is the sugar component found in corn.

      I just found out a few days ago that some salt like table salt contains dextrose that’s derived from corn. I’ve been thinking about getting rid of using table salt and just using my own kosher or Himalayan salt, but tbh I’m reluctant to do it. I’ve cut out a lot of things and I don’t really want to cut out anything else that I’m not sure will effect me…in a super small amount that it might be added to salts to stabilize the iodine. I don’t want to be further alienated when I have to go to a restaurant with my friends. Also most of the items at my house that have salt in it canned food etc. are some of the few quick things I can eat- because I’m not the one paying for the food in my household and i can only ask for so much. I’m not in a place financially where I can get a lot of my specialized items- although my family tries their best to get items I Can actually stand. I get I can bring a my own salt with me at a restaurant and ask for no seasoning but it feels like a lot to me- cause I already check for cross contamination and ask if the food has like a high volume of corn in it like cornstarch etc. I’ve also heard most dextrose is not derived from the Zein (corn gluten) portion of it- so it might be safe- but idk if that’s true. I just wanna know if anyone actually responded to it negatively.

      I’m so confused…

      For my first couple of years after discovering my celiac disease I also had to avoid cow's milk/casein and eggs, as well as other things, but could tolerate duck eggs and sheep and goat's milk products. I'm not sure if you've tried those, but it could be worth testing them out.

      Hello, @Kwinkle, How are you doing?   Have you tried adding a Magnesium supplement?   The B Complex vitamins need magnesium to work properly, especially thiamine vitamin B 1.   Magnesium deficiency symptoms and Thiamine deficiency symptoms both include gas and bloating.  Thiamine deficiency symptoms also include loss of appetite and fatigue.   My gas and bloating resolved rather quickly when I took Benfotiamine (a form of thiamine shown to promote intestinal healing) and Magnesium Glycinate in addition to my B 50 Complex (all twice a day plus the following...).   I found Magnesium L-Threonate or Magnesium Taurate are better when taken with a form of thiamine called TTFD (Tetrahydrofurfuryl dusulfide) because all of these cross the blood brain barrier easily, which corrects the loss of appetite, fatigue and anxiety.    Like @Celiacandme said, keeping a food/mood/poo'd journal is a big help in finding problematic foods, and for making sure your diet is not carbohydrate heavy.  If you're eating a lot if processed gluten free facsimile foods, be aware they do not have vitamins and minerals added to them like their gluten containing counterparts.  For every 1000 kcal of carbohydrates, we need an extra 500 mg of thiamine to turn them into energy and not store them as fat.   Let us know how you're doing!

      Testing

      Yes, if you had symptoms when eating gluten ruling out celiac disease won't necessarily mean you'll be able to eat gluten again, although it might mean that you may be able to be less strict with your gluten-free diet.
