Blood Allergy Testing

You’ve met the type.  They can’t eat a damn thing because of their allergies.  I felt so sorry for them and was soooo glad that I didn’t have to worry about such things.  I just had a few digestive issues because I was told I had IBS.  Well, with years of ignoring WHY I had IBS, I am now one of those people who can hardly eat anything because of my allergies/sensitivities.  I’m now one of THEM!  And… we’re growing fast.

Going Gluten FreeI last spoke about how I started my journey to better health by going gluten free the wrong way.  In that post I mentioned the first food allergy testing I did and wanted to share that with you.

Like many folks, I’ve had digestive issues my whole life and, like many folks, I didn’t want to get food allergy tests for fear I would be told I can’t eat all the things I love.  Well, if this sounds like you too, I’m here to tell you stop putting this off!  The longer you wait to figure this out, the worse off you could end up. 

If you have digestive issues, you need to figure out the root of the problem, and many times it’s more than just a simple food allergy.  Getting a blood food allergy test is a great start to getting you some immediate relief WHILE you and your doctor start to navigate to the source, or sources of the problem. 

Side note:  I mentioned, “your doctor”.  Unfortunately this can not be a traditional doctor.  Some GI specialists might do some testing but a functional or natropathic doctor is the one who is all about these kinds of tests.

TBlood Allergy Food Testinghrough my doctor, I got a General Food Panel test.  This test looks for elevated amounts of antibodies in your blood that are triggered by specific foods.  You see, when you have an intolerance for a certain food, your body’s immune system will overreact and see this food as a toxin, even though it’s really harmless.  It will then create these antibodies to fight this toxin and this fight is what gives you a reaction.

The antibodies, or immunoglobulins I was tested for were IgA, IgG, and IgE.  My doctor explained that the first two would be a milder intolerant reaction, where the third antibody, the IgE, would possibly show a more severe reaction, an allergic reaction – an autoimmune response.  An autoimmune response is where you get a rash, or itchy skin, or it triggers rheumatoid arthritis.

Also, from what I’ve been reading, these three antibodies are found in different systems in the body.  I’ve asked both doctors about these antibodies and the difference between the three.  Their answers still confuse me, so I still have much to learn about all this.

Food Panel Allergy TestAbove is page one of my food allergy panel.  If you read my previous post, I mentioned a dinner that I had at a lovely restaurant where I had a really bad reaction.  I was sick all night.  I found out later that the bread that I ate was made from amaranth.  As you can see on the chart, I’m extremely intolerant of amaranth.  I was so glad to learn this.  Many gluten free products contain amaranth.

Also, before the testing I was having a really bad reaction to soy sauce.  As you can see, soy triggered IgA to spike on the chart.  For me, even though the chart is measuring soy in a “low tolerance” level, for me, that meant a severe reaction involving a bathroom multiple times. 

Food Allergy Panel TestAbove is page two of my test.  Fabulous – all types of dairy are triggers.  I was so sad to learn this.  Man, I miss cheese.  I also can’t have eggs, sugar cane, banana (seriously?), pineapple, lobster, shrimp, and crab. 


Ok, now someone’s just torturing me.  I grew up eating Maryland crab cakes people.  This breaks my heart.  But also explains a lot.  Remember I said I’ve had digestive issues my whole life?  I grew up eating every single item that is a trigger on all these pages.

Food Allergy Test PanelThis is the last page of my first food test.  For cryin’ out loud.  I also can’t have millet?  That’s birdseed, a very cheap gluten free grain that is also used in a lot of gluten free products.  I’ve now become the crazy lady at the grocery store who is reading the labels of food and cursing out loud when I see that there is amaranth and millet in what would have been a lovely GF option for me to eat.

I would not have known any of this if it weren’t for my tests.  So that’s a good thing.  I’m getting some answers to what’s been ailing me for a long time.

I had no idea that my going gluten free experiment was going to take me down this path, and this is just the beginning. 

For my next post, I will talk about the second test I did – the stool test.  If you had told me five years ago I’d be writing a blog and talking about crap, I would have been offended and thought you were crazy.

Until then!

Disclaimer:  Clearly, I am not a doctor.  I’m writing these posts to share my story and to hopefully inspire you to seek help from a great Functional and/or Naturopathic doctor.  Any advice I am giving here is simply my opinion based on what I’ve learned through my own experience with a lifetime of digestive disorders.  Also, this is not a paid endorsement for any products or labs I might mention.

    Christina, I’m sorry to hear you’ve joined the same club I’m in – I have celiac disease and a reaction to the proteins in dairy. I tested positive for a lot more foods, just like you did, but after eliminating them completely for 6 months, I’ve been able to add back eggs, gluten-free oats, cranberries and other foods – in modest amounts and not every day. Best of luck to you! BTW – I just discovered the blog and love it – thank you for sharing so much info.

      Hi Suzanne! Thanks for commenting here. I wish I could be tested for celiac disease. As I did this the wrong way, I can’t now and I’m not about to eat gluten again for 6 weeks to do that test either! That’s great you can eat some foods again after only 6 months. That gives me hope. I’m still trying to figure all this about and as you know, it’s a huge process of elimination. Best of luck to you as well.
