Where To Get An Intolerance Testing Kit

Bloating, nausea, fatigue – there are all kinds of symptoms you might experience if you’re living with an intolerance. Not only can these sensations be incredibly uncomfortable, but they can also be dangerous if your intolerance is severe.

Unidentified intolerances can lead to conditions such as nutrient deficiencies and even an irritated gut. That means it’s crucial to get an intolerance testing kit as soon as you can, if you’re experiencing symptoms. But where can you find one that’s quick, easy and reliable?

At Lifelab Testing, we offer intolerance testing kits that contain everything you need to take a small blood sample in the comfort of your home. Learn more about our simple test kits below.

Basic intolerance testing kit

Do you suspect you know what’s to blame for your symptoms? If you’ve noticed that you consistently feel discomfort a couple of hours after eating a potential allergen (for example, gluten, dairy or milk), our basic intolerance testing kit is for you.

The basic kit can test for 40 common food and drink intolerances, is easy-to-use and delivered direct to your door. All you need to do is follow the instructions to take a quick skin-prick blood test at home, before sending it back to our scientists using the prepaid packaging provided.

Our team will analyse your sample, searching for an antibody known as IgG4. This is produced by your immune system every time you eat something that sparks your intolerance. A high presence of IgG4 will help us identify the substance that’s causing your problems.

Complete intolerance testing kit

Alternatively, you may have no idea what’s causing your symptoms. Almost anything can spark a food intolerance, so don’t give up if you’ve ruled out the common antigens such as gluten and lactose.

Our complete intolerance testing kit can identify 160 key food and drink intolerances in just one sample. This makes it a lot quicker and easier than other methods of diagnosis, such as the elimination method. Imagine trying to cut out 160 different foods in turn!

Once you’ve taken your test and received your results, our complete test also gives you access to a free 30-minute consultation with a qualified nutritionist. They will be able to guide you through the results of your test and advise you on any dietary steps to take in the future.

Order your intolerance testing kit

If you suspect you have a food intolerance, it’s important to find out for sure to prevent the problem from getting worse. Our certified team promise 100% accurate results or your money back. So what are you waiting for? Order your intolerance test from Lifelab Testing today.

Do You Have Gluten Intolerance?

With whole aisles dedicated to “Free-From” foods, it’s become apparent that people are looking to understand their body’s more fully. Over the last decade, a movement has been quietly taking place where people are taking allergy and intolerance tests to identify foods that are adversely affecting their health. Gluten intolerance is one of the most common, with many people realising that foods containing gluten cause them a lot of problems. But how do you know if you have a gluten intolerance? When is it time to take an intolerance test?

What Is Gluten?

Gluten is a group of proteins that is found exclusively in grains and is the primary component in flour that makes it sticky when water is added. It works to bind dough and give it the elastic texture before baking. It also helps with rising and contributes to the texture of the final baked product.

What’s The Problem With Gluten?

There are a growing number of scientists who think that gluten may actually be a problematic food for the MAJORITY of the population. However, currently, the generally accepted rule is that most people can tolerate gluten just fine. The problems come where there is gluten intolerance or coeliac disease.

Gluten Intolerance

Gluten intolerance is less severe than coeliac disease but can still have a significant adverse effect on your day-to-day life. Symptoms of gluten intolerance include diarrhoea, stomach pain, tiredness, and bloating. To identify a gluten intolerance, you can take an intolerance test.

Coeliac Disease

Believed to affect 0.7-1% of the population, Coeliac Disease is a lifelong condition which manifests in several life-affecting symptoms. These include tissue damage within the small intestines, severe weight loss, diarrhoea, constant fatigue and anaemia. Coeliac has to be managed sufficiently to avoid increased risk of many diseases, including diabetes.

Gluten Foods & Gluten-Free Alternatives

Aisles are now dedicated to gluten-free foods

Unfortunately for those with gluten intolerance and coeliac disease, some of the most popular foods contain gluten. Pizza, bread, beer, cakes & pasta are just some of the foods that are rich in gluten. The increasing awareness of the prevalence of gluten intolerance has led to many of the big food manufacturers producing gluten-free versions of your favourite foods. From pizza to beer, pretty much every food containing gluten has been given a gluten-free makeover.

Identifying A Gluten Intolerance

The best way to identify a gluten intolerance when you realise you’re experiencing the above symptoms when eating gluten-based foods is via an intolerance test. By taking an intolerance test, you can confirm your suspicions or discover whether it is another food that is causing you problems.

What is the Low FODMAP Diet?

What is the Low FODMAP Diet?

The low FODMAP diet is a particular kind of diet that eliminates what are referred to as ’High FODMAP’ foods. It is known to be especially effective at helping sufferers of IBS control their symptoms.

The term ‘FODMAP’ is an acronym that stands for Fermentable Oligo-, Di-, Mono-saccharides, and Polyols. These are a specific group of carbohydrates that tend to be poorly absorbed by the body. FODMAPs can produce diarrhoea or constipation, bloating, wind and abdominal pain in those with gastrointestinal symptoms.

Fodmap Foods to Avoid

The major FODMAPs are; fructose, fructans, GOS, lactose and polyols. Below are a few examples of foods containing these FODMAPs.

Fructose – Honey, low-calorie yoghurt, various fruits, high fructose corn syrup, agave and figs.

Fructans – Wheat, rye, onions, watermelon, dried fruit, nectarine and garlic

GOS – Legumes, cabbage, cashews and pistachios

Lactose – Many dairy items, some bread and baked goods, salad dressings, deli meats and margarine.

Polyols – Found in a lot of marketed ‘health foods’, such as protein bars, to minimise the sugar content. Also found in cauliflower, apples, apricots, mushrooms and several sugar alcohol additives.

Low FODMAP foods

Now, it’s important to note that this diet isn’t all black and white. For starters, the low FODMAP diet is just that, Low in FODMAPs. It’s okay to consume foods with small amounts of these. So long as you avoid those high FODMAP foods, you’re good to go.

Hence, foods that are low in FODMAPs, such as polyols and fructose, but still contain them can be consumed. Here’s a short list of Low FODMAP foods;


Banana, blueberry, grapes, honeydew, melon, lemon, raspberry, strawberry, rhubarb and lime


Broccoli, carrots, celery, ginger, green beans, lettuce, olives, parsnip, potato, pumpkin, spinach, swede, sweet potato, tomato and turnip


100% spelt bread, rice, oats, polenta and quinoa

Milk Products

Hard cheeses, brie and camembert, gelati and sorbet


Artificial sweeteners (not ending in ‘-ol’), molasses and treacle. Also sugar, golden syrup and maple syrup in small quantities.

Please note that this list isn’t exhaustive and there are likely many other foods which the Low FODMAP diet permits, this is just a good starting point.

Tailoring Your FODMAP Diet

The low FODMAP diet isn’t one-size-fits-all. It’s most useful when fine-tuned to the individual. This is because not all FODMAPs will be a trigger for you, and once you’ve tailored the diet to your specific triggers, it becomes quite easy to follow.

Also, you should never completely eliminate FODMAP foods for an extended time.

See, FODMAPs are prebiotics, and they encourage the growth of good bacteria in your gut. They are essential for long term gut health. Studies have shown a strict low FODMAP diet can harm gut bacteria.

You can effectively tailor your FODMAP diet through the use of food intolerance testing. A food intolerance test can highlight which High FODMAP foods are likely to be the primary cause of your symptoms. After this, you can exclude them altogether, or use an elimination diet, and slowly reintegrate them back into your diet after 4-8 weeks of elimination.

Intolerance testing is an excellent way of keeping non-offending high FODMAP foods in your diet while ensuring your gut health stays optimal.

Alternatively, you could completely eliminate all FODMAPs for a short period and bring them back into your diet again after a while. Although, this may take longer to complete, as some foods reintroduced may cause digestive symptoms again when reintroduced. It’s far more efficient to narrow down the list of potential offenders.

Can an Elimination Diet Cause Nausea?

Elimination diets aren’t a walk in the park, especially if one of the foods you’re eliminating is something you were previously eating daily. But they’re a pretty important step following a food intolerance test.

The good news is that an elimination diet doesn’t cause nausea in and of itself. But it could indirectly be causing you nausea. There are a few ways this can happen. Let’s explore them.

Missing Essential Nutrients in Your Diet

A nutrient deficiency could cause your nausea. Beginning an elimination diet without making sure you replace the vitamins and minerals that are in the food you’re scrapping can cause various adverse reactions in your body.

Nausea is a common symptom of vitamin B12, magnesium and vitamin D deficiencies. You can essentially become deficient in these nutrients if you’ve suddenly excluded the only primary source of it from your diet. We recommend looking at the nutrients stored in the foods you’ve eliminated and seek to substitute them with foods of a similar vitamin and mineral contents.

Caffeine Withdrawal

If you’ve abruptly withdrawn from drinking coffee or consuming caffeine as part of your elimination diet, it could be a withdrawal symptom.

As caffeine is quite an addictive substance, many people can experience withdrawal effects if they suddenly stop consuming it. Symptoms include irritability, nausea, fatigue, low energy and poor concentration.

Experts recommend that those who experience these symptoms wean themselves off of caffeine, instead of quitting cold turkey. Try cutting down one cup at a time. Weakening your coffee could also help to reduce your intake. 

You’re Genuinely Under the Weather

It could just be that you’re under the weather with a cold, or feeling run down. Stress, smoking, drinking alcohol and several other factors can all contribute to lowering your immune system and make you more susceptible to catching a travelling cold.

Diabetes and other immune system disorders can also severely impact your immune system. It may just be a coincidence that feeling unwell has followed you starting an elimination diet.

Don’t let this tempt you to break your elimination diet streak. You’re much better off following through, provided you maintain nutrient balance than going back to experiencing daily frustrations and symptoms of which you can’t narrow down the cause.

To make your elimination diet even more effective, consider getting an intolerance test, to indicate which foods you’re intolerant to so that you only eliminate what’s necessary.

What They Don’t Tell You About The Gluten-Free Diet

With estimates of 1 in 100 people worldwide living with celiac disease and many more suffering some form of gluten intolerance, the gluten-free diet is becoming increasingly popular as a health optimisation tool. However, it is also gaining traction as a weight loss diet.

Here we look at how getting this diet wrong can actually lead to weight gain.

Gluten Intolerance

A lot is still unknown about gluten intolerance or sensitivity, but anecdotal reports have shown many people experiencing an improvement in negative symptoms. Symptoms associated with gluten intolerance include:

  • Bloating
  • Diarrhoea
  • Abdominal Pain
  • Fatigue

In the quest for relief of these life-altering symptoms, many have turned to gluten as a potential causing factor. You can assess your tolerance for gluten with one of our tests and, if you discover you do have sensitivities, we offer full support in undertaking an elimination diet.

Going Gluten-Free

Given that gluten intolerance restricts your access to foods traditionally considered unhealthy; breads, processed foods and starchy carbohydrates, you’d expect that a welcome side effect of your condition would be weight loss.

But this isn’t necessarily always the case. The rapid growth of the gluten-free market has led manufacturers to replace all of your favourite foods with gluten-free alternatives. In their quest to achieve foods that taste just as good as the originals, some have turned to sugars and fats in excessive quantities.

Gluten-free Pizza -a cheesy, stringy godsend

There are also considerations to be made about the gluten-free ingredients that are used in baking and cooking. White rice flour, whilst gluten-free, can induce a dramatic rise in blood sugar and contain very little nutritional value.

So, gluten-free foods aren’t as they seem right? Well, no.

Doing Gluten-Free Right

Going gluten-free should be seen as an opportunity to move to a whole foods led diet. Fresh fruit and vegetables are all gluten-free and contain a lot of the vitamins and minerals required to maintain a healthy lifestyle. It’s important to note, however, that processed fruits are not necessarily gluten intolerance friendly.

Fresh meats are also suitable for those living with a gluten intolerance. A fantastic source of protein, the building blocks of muscle, they’re also incredibly satiating and help you to avoid the temptation of the foods that aggravate your gluten intolerance. Be careful of processed meats, however, as they are likely NOT gluten-free.

Whole fruit and vegetables – gluten-free so fill your boots.

Going gluten-free can lead to a total lifestyle revolution. It affords you the opportunity to explore a wealth of foods and also learn or develop cooking skills and even create your own recipes.

To discover whether you have gluten intolerance and would benefit from a shift to a gluten-free lifestyle, take one of our tests. Following your results, we offer full support in completing an elimination diet to optimise your health moving forward.

How Do I Know If I Have Lactose Intolerance?

Between 30 and 50 million adults have Lactose Intolerance making it quite common. The question is, are you lactose intolerant?

Several different symptoms come with a lactose intolerance, and they usually occur within a few hours of consumption. Below are a few symptoms that may indicate an issue if they coincide with eating products that contain lactose.


It makes sense that consuming foods you’re intolerant to would disrupt your digestive system and lactose can have a real impact on your bathroom trips. Diarrhoea after lactose is an indicator of an issue and can lead to dehydration and electrolyte imbalance.

Stomach Cramps and Pains

As well as diarrhoea, people with lactose intolerance will often experience extreme stomach cramps. The gases produced by the stomach fermentation process cause this pain. The pain and bloating experience is not related to the amount of lactose imbibed, but the level of intolerance the individual has.

pile of cheese causes lactose intolerance


If you’re passing infrequent, hard stools or are having to strain excessively, you are likely experiencing constipation. Bacteria ferment the undigested lactose in the stomach, which produces methane gas and this gas is thought to slow down the movement of food through the gut. Constipation is less likely than diarrhoea but is still a potential symptom.

Other potential symptoms

Other symptoms that have possible ties to lactose intolerance include:

  • Extreme Fatigue
  • Headaches
  • Brain Fog
  • Eczema
  • Joint Pain

Though they have not been proven as established symptoms, they have been reported frequently in case studies.

Other intolerances or allergies cause all of the above symptoms. To establish what might be causing the above symptoms for you, you should take an intolerance test.

Why Lifelab is with Trusted Shops

Reviews help us all out online. They clarify, reassure and occasionally, deter us from making an order. But it’s also the unfortunate truth that there’s a plethora of bogus reviews and testimonials online. With so much content out there, it’s hard for anyone to police the claims people make, for or against online businesses. 

So, we’re all becoming more and more cynical and untrusting of what we see online. But is there anything we can trust? What about the likes of trust pilot – which was set-up initially to resolve this very issue? It doesn’t look all that promising.

This is why we’ve opted for using Trusted Shops as our chosen trust brand. Trusted Shops leaves no room for fake reviews – you must be a registered, verified customer to leave a review – and all online stores boasting a trusted shops badge must adhere to strict criteria. It means our customers can order with confidence.

Real Reviews from Real People

Only verified customers can leave a review, so you can toss out any worries of reading robot opinions. No repeating reviews either, so businesses can’t game the system into getting a manufactured high rating. You’ll only read the thoughts and experiences of real people.

Companies are Held Accountable

It’s not just any old company that can gain the coveted Trusted Shops badge. As mentioned earlier, companies must meet strict criteria to display the Trusted Shops Trustmark. These criteria include having excellent customer service and even specific legal requirements.

This triad of features is a hallmark of providing excellent online shopping experience. Google even recognises them, showing Trusted Shops provided ratings within search results.

It only made sense that we should partner up with this excellent trust brand.

Customers can now openly and honestly voice their opinion, experience and suggestions, without being outnumbered by illegitimate feedback. We want our customers to feel complete confidence when purchasing their test from us, and Trusted Shops provides exactly that.

How Intolerance Testing Positively Impacts Your Diet

We all want to lead a healthy and happy life and are primarily responsible for our own health (except for that which we can’t control like the spread of diseases). A major factor in how healthy we are is our diet. One of the biggest challenges with a healthy diet is working around what responds badly to and tailoring towards foods that your body uses optimally. An effective starting point for this is intolerance testing.

How can intolerance testing impact my health?

Finding out that you have a food intolerance might make you feel as though your whole lifestyle and relationship with food has to change. You’ll indeed be best to make some changes, but they don’t have to be changes for the worse. You may even find that working with your body instead of against proves to be more liberating than restricting. 

You learn what your “healthy” is: Each of us will have a different version of healthy, as it relates to how our body responds to certain foods, as well as keeping ourselves nourished and free from disease. Most of us would consider two scoops of ice cream for dessert to be healthier than a giant chocolate brownie (complete with a drizzling of chocolate sauce) bur if you happen to be intolerant to lactose or dairy, the latter may cause you less misery (though it’s certainly not the best option). The same could be said for choosing whole-grain toast for breakfast- ideal for some, but certainly not for coeliacs’ or those who are wheat intolerant.

  • Understanding helps you become healthier: If you don’t know where you’re going, how will you get there? Using your body as a guide, listening to what it’s telling you and which foods it’s finding trouble with can help you become healthier overall, as you’ll be able to mediate what were once mysterious symptoms. The less trouble you give your body, the more it can work on keeping you at optimal health, instead of fending against trigger foods. 
  • You can enjoy your meals again: Another solid impact intolerance testing can have on your health is that you can get back to enjoying food again. Once you know where the problem is, you’re free to experiment with new recipes and meals (without those ingredients that were responsible for your symptoms) and enjoy the freedom of eating quality food again. This all equates to a happy and healthy body.

How your Diet is impacted by Food Intolerances

A common misconception is that having a food intolerance flips your diet upside down, in a bad way, but this isn’t the case. In fact, your diet can become far more varied once you understand what foods you’re intolerant to. You can use this new insight to enjoy a diverse, delicious and healthy diet in a way that you just weren’t able to before the food intolerance results.

When you understand what your body needs to take care of itself, you are equipping yourself to enjoy a healthy and happy life, one meal at a time. Food intolerance testing is often the key to unlocking a healthy diet, and it can be yours within the week. Are you ready to unlock a healthy future?

Heal your Gut

Here at Lifelab Testing, we’re dedicated to helping teach our readers how they can best improve their health. The gut has a major impact on one’s health, since it determines what nutrients your body absorbs, and which toxins, allergens, and microbes are kept out. It heavily impacts the health of your entire body. Many factors affect gut health, such as diet, food intolerances, lifestyle, hormones, sleep, and medications. These all affect how your gut digests and manages what you consume. We’ve put together a few tips to help you heal your gut.


Consuming probiotics is an excellent way to reintroduce healthy bacteria into your digestive tract. Remember that probiotics are the good bacteria that are essential to proper gut health.

You can consume probiotics by taking a probiotic supplement or adding fermented foods to your diet. We’d recommend starting with the latter, rather than running to the supplement aisle right away (unless your doctor recommends you do so).

Probiotic-containing foods include;

  • Fermented vegetables
  • Yoghurt
  • Kimchi
  • Kefir
  • Sauerkraut
  • Tempeh
  • Kombucha
  • Miso


Prebiotics are how you can nourish those healthy bacteria, so they stick around and keep helping your gut. Think of it as feeding the good guys.

Probiotics eat prebiotics, which are natural soluble fibres, and then produce short-chain fatty acids, inhibiting the growth of pathogens and prevent disease. Ultimately, this helps maintain your intestinal and overall health.

Here’s a list of prebiotic foods you can add to your diet;

  • Bananas
  • Jerusalem Artichoke
  • Onions
  • Asparagus
  • Chicory
  • Whole Grains
  • Garlic


Ginger has various health benefits, from blood-thinning (great for preventing blood clots) to relaxing muscles. One gut-helping example is the smooth muscle of the intestines. This is a godsend for those who suffer from gas or cramping. As if that wasn’t enough, ginger can also stimulate saliva, bile and gastric enzymes, making it an all-around supporter in your digestion.


FODMAPs (Fermentable Oligo-, Di-, Mono-saccharides And Polyols) are short-chain carbohydrates found in certain types of food, such as wheat and beans. Studies show a strong link between FODMAPs and digestive symptoms like stomach pain, bloating, gas, diarrhoea and constipation. Low-FODMAP diets are shown to provide exceptional benefits for many people with common digestive issues.

Here are of a few high FODMAP foods to avoid;

  • Beer
  • Fortified wines
  • Soymilk
  • Milk (from cows, goats and sheep) and other dairy products
  • Fruits
  • Beans and Lentils
  • Barley
  • Rye
  • Fructose
  • Wheat 

It might feel overwhelming to start with, but we can help you on your path to a healthier gut. Purchase an intolerance test today, to quickly find out which foods that are currently a problem and shorten your initial elimination phase.

Allergy People making a difference

There are so many people looking to make a difference in their lifestyle and diet, but it does not stop there. Allergy testing people are making a difference and spreading the word, so we thought it was time to celebrate their awareness and ability. Look at how we have helped some of our customers to improve their lives, and how they have spread their own awareness.

Chris Jones – Lifelab Testimonial

“My experience was great, particularly as I messed the first one up so getting a second kit was easy.  I was intrigued by the results and have found that reflecting this in my diet has helped my health and well-being. But overall the whole process was easy and I would recommend, in fact, I already have. Thanks!” – Chris wanted to make a change in his life, and he was dedicated to improving his diet. He did this withLifelab Testing and allergy testing kits, and he loved the whole process, recommending it to any others who suffer from food allergies.

Danielle Lloyd – Spreading the word

We’re absolutely delighted to have helped model and TV star: the AMAZING Danielle Lloyd, kickstart her year in the best way possible by helping her discover her Intolerances with an easy to use at-home Intolerance Test ? Just take a look at what she had to say about her Lifelab Testing experience below! ??

“I’m starting the new year feeling great after finding out what was causing me bloating and pain after eating food, with Lifelab Testing‘s at-home intolerance and allergy testing kit. The results were so good that my son Harry did a test, too, and since changing his diet to gluten free, he hasn’t been in any pain. My results showed I had to cut out eggs, yoghurt and white beans, which I eat regularly as part of a healthy diet, so it’s been a total change but it’s for the better and means I’m not bloating after meals anymore! The test was so easy to do and really thorough as it checks over 159 intolerances, so I knew it’d be a good way of finding out what was causing the pain.”

Danielle Lloyd is spreading the benefits of understanding your allergies and intolerances

Lauren McQueen spreading the news

We are so proud to have helped people cope with their allergies, and with people coming to us and ask how we could help them with their allergies through allergy testing, they wanted to spread the word. Lauren McQueen was another one, check out her testimonial below and also, you can hop over to Instagram to find out more:

I have been struggling with bad breakouts on my skin alongside extreme bloating of my stomach. I contacted Lifelab Testing and purchased their Complete Intolerance Test without any hesitation. I took my blood sample and returned it to Lifelab for testing. Within days, my results were ready in the ‘my account’ section. After I studied my results, I was put in contact with Lifelab Testing’s Nutritional Therapist who helped me to understand my results more and how to structure my diet around this. With this knowledge, I am now aware of what I should eat less of and what to completely avoid.

Lauren shared her experience on her Instagram page, and utilising our nutritional therapists, she was able to improve her health and lifestyle. We are very keen to see people spread the word about allergies and healthy living.
