We LOVE making our customers happy! Check out this amazing review from Brittany:
“I recently received my test results and was found to have a gluten intolerance, among other things. Ironically, six months ago I tried a gluten-free diet and stuck with it for at least 3-4 months and felt great – but the holidays came and I quit. Ever since quitting my stomach and digestive issues have been horrible. Not really knowing what was wrong with me, my father recommended me to get my tolerance levels tested. To my shock, I am 100% intolerant to wheat and nearly 100% intolerant to gluten.
Looking back I think I have had this sensitivity my whole life, I just never knew what to call it. I remember being in college classes embarrassed at my stomach always rumbling. I always sat in the back just in case I needed a bathroom break.
Truly, I cannot thank you enough for alleviating me of this issue.
An answered prayer.”

Thank you very much for providing me with useful information that has really improved my health! I have eliminated the foods that you recommended and have been thrilled to add back some foods that I previously thought were problems for me. I feel so much better! I have recommended your testing to many people. Thank you!

“I ordered an allergy test for my mother who is 71 as of today, she’s been having some stomach issues and wanted to find out exactly what was wrong, the doctors couldn’t tell her… But only through the results of this awesome and easy to do allergy test by Test Your Intolerance, was she able to get the results that she needed! There was a huge list of things that she’s been regularly consuming which are healthy, but we were both surprised to see the very detailed results of certain foods that just don’t work with her body or system. Now my mom can make those subtle food changes and have a much happier stomach and not be questioning everything she eats.”
“I heard about the intolerance test from a friend who successfully proved to her boyfriend that she was gluten intolerant with this test. I gave up gluten years ago but was having some new issues of extreme exhaustion.
After taking this test, it changed my life. My eyes were no longer twitching and heavy all day. I no longer felt exhausted all day long. Since I’ve given it up, I can now feel the difference almost immediately.
So, after I had such great results with the test, I forced my friend Rebecca to order it as well who was having acne issues. I told her it was probably something she ate every day and after we got her results it was. Cheese. Her face has almost completely cleared up. A surprise bonus for her on taking the test was finding what was causing her terrible constipation. Corn.
We both swear by this test and have recommended it to many of our family and friends. The price is reasonable and totally worth it.”
Hospital recommended a test so I bought this one. They were happy with the results and it has allowed me to change my diet.Steven Lloyd Via Google
I’ve got a few tests to try and see what was giving me headaches, but this one gave the best results and I could ask more questions on the livechat. Awesome.Andrew Vallejos Via Google
what sort of allergy symptoms has your child been having? Mine had a terrible face rash so I got an Allergy Test, I’m glad I did! He’s allergic to a range of dairy products, so we went dairy free and he’s had no rash. Five stars!Kylie Buckland Via Google
I spoke to the customer service team first of all who are based in the UK but work 24 hours a day and they helped me get the right test. I was a little worried about sending things through the post but my results came back to my inbox and were so cool. I now stay away from gluten and I can’t believe how much better I feel.Mary J Benfield Via Google
I wanted an allergy test where I didn’t need to send in blood, and this one uses hair. The results came quickly and have really been a great help.Caroline Lauren Via Google
Got this test to help with my on-going IBS. The test is easy to understand and well explained, but they do send your sample to the UK which I didn’t realise.Chloe Sanderson Via Google
I bought this test for my family after I got my results, it’s really helpful and means we have less of a worry at meal times now as we know what people need to not eat. Great test.John E. Klein Via Google
I was a huge coffee drinker, but always had headaches, so thought I needed to give up coffee. I got an allergy test and found I had an intolerance to a few different fruits and vegetables, I’ve cut these out and now I still drink coffee, without the headaches.

Before I became a Partner I did a test on myself and I was surprised to find I was intolerant to avocado. I used to eat them almost daily. As soon as I eliminated them from my diet my acne cleared up!! Test was easy and results are emailed fast. Now I am a partner and offer this great service to my clients.
Root and Remedy
“I am beyond ecstatic to have found this comprehensive allergy test. There isn’t anther comparable product on the market! Not only does this test indicate problematic foods, but also non-food items as well. I was able to indicate the root cause of several of my client’s health issues and provide long term relief for them. Everyone should take this test! It is most definitely a game-changer”.
With the OCR world championships coming up I was searching for something that would enable me to be at my peak physical performance. I came across this test and I was amazed at the details it gave me. After replenishing the nutrients indicated naturally I feel better than ever, highly recommend this test for all sports men and women!
“As a business owner I wanted to have unique products that makes my salon stand out. When I found the test I was astounded at how easy the process was and I knew straight away I wanted to offer it to my customers. The feedback has been great and the team have been a pleasure to deal with.”
Cort, 6, got psoriasis in March 2014 – we didn’t know what it was at first, and one doctor suspected a viral eczema. We saw an allergist, two pediatricians, and a dermatologist. During this time it continued to escalate. We finally requested a biopsy and found that it was psoriasis. We later discovered that psoriasis runs on both sides of the family.
We were prescribed many different steroid creams (two for his hair, three for his skin), as well as oral steroids. We were spending about $90 a month on steroids, with insurance.
The steroids made Cort feel very angry and emotional. His skin only responded to one of the steroid creams, but it was so dangerous that he had to be monitored every couple of days to make sure his skin wasn’t thinning too much. I tried some more natural remedies, since I didn’t like him being on so many steroids, but they did not help either.
Last summer I started an elimination diet. Because we didn’t know what was causing the issue, the things we eliminated were a shot in the dark. Now that we have his results, it turns out that only one of the many foods we eliminated was something he shouldn’t have had (bell peppers). We did sun therapy every day in the summer.
When he started back to school in August, he was off numerous foods, but his skin was flaring so badly that he started to feel sad every day because other kids were asking about it. He had trouble sleeping at night, because it would itch and burn so badly (sometimes he scratched until it bled).
I started looking online for a place to have food intolerance testing done, since I couldn’t seem to convince any of his specialists to order the test. That is when I found The Intolerance Testing Group.
Once we got the results back, we took him off all the foods on the list. Your tests also showed a high build up of yeast in his system. We took him off all yeast, and then started using some natural methods to help with his digestive health (aloe vera, caprylic acid, coconut water, probiotics). I took him off all steroids, and started using an organic castor oil on his skin.
Within a week we started to see a difference. The spots of psoriasis were started to turn white in the center. With the steroids, they healed from the outside in, but with the dietary changes they were healing from the inside out.
I suspect some of the big irritants for Cort were the dairy and chocolate. His skin is cleared up now (you can just see white spots where the psoriasis used to be), and we have slowly let him start having trace amounts of some of the things on the list (like onion powder or sunflower oil that is mixed in with other foods). We plan to keep him off most of the foods on the list from here on. When Cort goes to a birthday party, he takes his own cupcakes that don’t have any milk. He keeps a bag of special snacks at school for parties there. And on Halloween, he traded all his chocolate candy for a yo yo that he wanted from the store. Because he is so happy to have clear skin that doesn’t itch and burn, he doesn’t mind having to make a few sacrifices.
I haven’t always had problem skin; it only seemed to develop once I hit my twenties. I tried absolutely everything to treat the acne: antibiotics, laser treatment, natural remedies, chemical treatments and microdermabrasion. Unfortunately, none of these things seems to have much of an effect and only left me more and more frustrated.
A friend told me about Test My Intolerance, as she had been tested and lost 40lbs after eliminating her problem foods. I was sceptical at first as I had never heard of this type of testing. The company offers a full money back guarantee, so I figured I had nothing to lose.
The ordering process was quick and simple and the fact that you download the test submission form means you can send your sample in the mail the same day. This really appealed to me because I was eager to get my results as quickly as possible.I received my results within five days of my sample arriving at the testing facility.
The recommendation from the company is to eliminate all items in my report for a minimum of four weeks. This was a challenge as many of the items in my report were my favourite foods!
After two weeks on the elimination diet my skin started to feel less greasy and angry.
By the end of the four weeks I could not believe the difference when looking back at old pictures of myself! My skin looked almost ‘normal’! All these years I’ve been trying to treat the surface of the skin and it didn’t even occur to me that the root cause may be what I’m putting into my body. I feel so much more comfortable in my own skin and would recommend the test to anyone suffering from skin conditions, especially acne.
I am going to continue with eliminating the offending foods and plan on taking the test again in six months.
