I got a Platinum intolerance test and I’m happy within results I received. Great and really quick service. Simple and Easy to read. Great experience. Would recommend. Thank you

Miss Liliana Lazuta

Easy to send in your hair sample and a reply with results very quickly. The test has confirmed what I suspected about some of the ordinary food I ate. I now know what to avoid and feel much better for it!

Bet Davies

A very straight forward process and cost effective compared to their competition, driven by the type of test (hair test not blood). Results within two days of sending sample, results were clear and understandable.

Peter Denton

Really impressed with these guys, efficient and friendly service, and got my results back just as they stated. Would definitely recommend them!

James Stallard

Very easy test, extremely quick results. Very pleased with results and will try to eliminate and see what difference it makes.


Time will tell if the results prove to be helpful, it was an avenue I wished to explore. I was happy with the overall service, the results coming through in just a few days. The staff were helpful and my emails were replied to directly.

My results came back very quickly. Some things I had suspected but there many surprises on the list. I cut things out and noticed the difference within a few days. My stomach doesn’t bloat any more and the noises it used to make (almost constantly) have stopped. I wish I had done this test years ago. I’d recommend them.

Got my results and a lot I eat show intolerance which is obviously why I get a lot of tummy upsets and bloating , making a start to cutting them out and hopefully in other month I would have successfully done so ,, it is definitely a good idea to take 3 months to get your system used to the change and also cooking changes

I have suffered with IBS symptoms for years and this was confirmed by my doctor . I tried to cut out foods that I thought were triggering my flare ups but could never pinpoint anything. I signed up for the testing with Intolerance Lab and had the results back within a few days ! I was amazed at what came up on the list , chicken was top of the list followed by oats and wheat . Since cutting out these foods my IBS symptoms have gone !! I no longer feel bloated and tired . No more stomach cramps or pains and I feel like have more energy ! I can’t thank these people enough ! It’s all such an easy process . I would recommend this company 100%

Had my doubts, but actually thought - why not? Results came back fast and queries answered within a day. Confirmed what I already knew, and raised a couple more issues which I have addressed and feel so much better! Worth the money.😁

Awesome service, results came back quite quickly. Because of the results, my tummy thanks me alot. There were things on the results I suspected and items I didn't. I would highly recommend this service to anyone.

Had my results back yesterday and Im intolerant of chicken amongst other things. Very surprising and going to look to change my diet. Great quick service

Emma Lucas

I sent mine off 31/12 and had them back 6/1, considering it was new year and weekends in between then I was very happy with the turnaround. The results have been amazing and far more accurate than I honestly expected. I’d been struggling with ibs and a weird histamine skin reaction for the last few months that was really getting to me. The doctors prescribed me with anti histamines and ‘the internet’ to help me manage my symptoms - wonderful right.. 🙄.... so when I saw the advert I thought I’d give it a go as was so fed up. My results came back with some things I’d never think of or have got from my food diaries. I instantly cut them out and my ibs and rashes have stopped overnight and I look slimmer. One of my top intolerances (99%) is Honey - yesterday I had some cough medicine forgetting there was 0.5g of Honey in it and I instantly came out in a rash. I was so dubious about this but honestly it’s really helped me, and for the price it’s brilliant.

Accurate results. Fast service.

Brilliant service, sent it on Tuesday and had the results by Thursday. Not so great for hubby tho, all the foods he loves he’s intolerant to. Three days in of cutting the foods out and the difference is amazing. I’ve been nagging for years to get himself checked. I ended up signing him up, so glad I did. Highly recommend.

Allergy and intolerance are often confused, or thought of as similar conditions, when in reality they are very different. Allergy is an immediate, sometimes dangerous or life-threatening reaction to a food or drink. This is often present from a young age and always involves the antibody type IgE. Intolerance can be developed later in life and takes longer for symptoms to present themselves, making it more difficult to pinpoint the culprit food(s). Testing can be beneficial to discover the trigger foods and drinks quicker. With suspected food allergy, always seek profesional medical help.

Some Health Insurance Providers will cover the costs. Contact your provider for more info.

We test for over 350 types of food, including wheat, eggs, nuts, etc. We also test for over 350 non-food items, like pet hair pollen and detergents. If you need a full list, get in touch and we can get you one.

We dont test anybody under the age of six.

Optimum nutrition during pregnancy and breastfeeding is vital for mother and child. To reduce any possible risk to the mother or baby, it’s Intolerance Lab’s protocol not to offer tests, advice or lifestyle changes during pregnancy and/or breastfeeding.

The tests are as painful as plucking a hair from your body..

Your hair does not have to come from your head. It can come from your leg, arm, or even chest.

This will not have any effect on the results.

No. Our tests examine your hair at the cellular level, so there’s no need for you to have been eating your trigger foods recently. They will still be found by our testing equipment.

These two tests are very different in what is tested, the process and the results. A blood test checks for IgE-mediated allergies and will only produce results listing reactions in the immunoglobulin system (these are estimated at only 2% of all allergies). Our hair sample test examines changes at the cellular level because the latest science shows that up to 43% of allergies are in fact a reaction in T cells. The two tests measure totally different reactions and will produce totally different results.

We only offer hair sampling here at Intolerance Lab. Currently, the main way to identify the two types of allergies (IgE and Non-IgE) is on the reaction time from consuming or being in contact with the item. If you notice a reaction that is almost instant or within two hours (max), you would normally consult with your GP and he or she might consider a blood test. These are normally essential for more serious allergies—which, fortunately, only account for 2% of all allergies. If your reaction time is slower or you are unable to identify the link between your symptoms then it is more than likely you have a non IgE mediated allergy. In this instance, we would recommend our hair based non IgE mediated allergy test.
