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.

The Difference Between Hay Fever and Covid

A few years ago, a sore throat, sudden loss of smell or wheezy cough might not have worried you. But as scientists continue to discover potential symptoms of coronavirus, the smallest sensation can now cause serious anxiety – and this could get even worse with hay fever season fast approaching.

From headaches to fatigue, there is a considerable overlap between the symptoms of hay fever and COVID-19. If you’ve noticed unusual symptoms but have received a negative covid test, hay fever testing could be the best way forward.  

In this blog post, we’ll share some key hay fever symptoms and explain how our complete body test could help you tell the difference between hay fever and COVID-19, and take control of your health.

What are the symptoms of hay fever?

We’re probably all familiar with the typical hay fever symptoms: a runny nose, itchy eyes and sneezing. But did you know there are a number of other hay fever symptoms that you may have overlooked? According to the NHS, these include:

  • Loss of smell
  • Earache
  • Headache
  • Fatigue (tiredness)
  • Blocked nose
  • Itchy throat, mouth, nose or ears

Several of these have also been identified as potential covid symptoms, so it’s important to get a reliable covid test first. But once that’s been ruled out, you may be wondering whether pollen is to blame for your discomfort.

How does hay fever testing work?

At Lifelab, our complete body allergy test will test for 40 different allergies. And it’s not just food and drink allergies we can identify. By testing a small sample of your blood, we can test for pollen-related antibodies that could indicate you have hay fever – i.e. an allergy to pollen.

If your symptoms are noticeably worse around certain plants, such as cut grass or crops in a field, you may already suspect that you have hay fever

Hay fever season is typically between late March and September as this is when the pollen count is highest. However, some people experience symptoms all year-round, so don’t wait until September for the sneezing to go away!

With a reliable hay fever test, you can get to the bottom of the problem and start managing your symptoms as soon as possible.

How Easy Is Testing For Food Allergies?

If you think you may have a food allergy, you’re not alone. According to research from NARF (the Natasha Allergy Research Foundation), the number of Brits with allergies is increasing by 5% every year. It’s important to find out whether you’re one of them – but how easy is testing for food allergies?

You may have heard about expensive clinics or complex hair tissue mineral analysis (hTMA). However, the good news is that testing for food allergies can be quick, easy and cost-effective. That means when you buy a food allergy test from Lifelab, there’s no need to tear your hair out – quite literally.

Read on to find out how easy it is to use our home allergy test kits.

What allergy tests do we offer?

At Lifelab Testing, we offer two allergy kits that make testing for food allergies easy. Both of these will test a small sample of your blood, checking for antibodies that could indicate you’ve had an allergic reaction.

If you have a strong suspicion about which allergen is causing your symptoms, opt for the basic allergy test. This kits tests for 35 known food and drink allergens. If you’re not sure what’s causing your symptoms or suspect it could be something more obscure, our complete body test will give you the answers you need.

How to use our food allergy tests

Once you’ve received your chosen test in the post, you can start using your kit. Each kit contains everything you need to safely take a small blood sample at home:

In response, your system releases a different type of immunoglobin known as IgG4. This can cause a range of uncomfortable symptoms, usually gastric issues such as bloating, nausea or diarrhoea.

  • 1 alcohol wipe
  • 1 plaster
  • 1 gauze pad
  • 1 transport tube
  • 1 blood sampling tube
  • 1 prepaid return envelope
  • 1 activation card
  • 2 lancets

Following the instructions in the test box, all you need to do is take a small blood sample and package it safely using the freepost packaging provided. Once we’ve received your sample, our certified technicians will turn your blood into plasma, making it easy to test for any antibodies.

What happens next?

The results of your blood test will be uploaded to your online customer account where you can download them securely. If you ordered a complete body test, you’ll also receive a free 30-minute consultation with a qualified nutritionist. They will be able to answer any of your questions and help you make informed, healthy decisions about your diet.

Allergy vs Intolerance

In the UK, allergies and intolerances are both a common problem – and the number of cases is increasing year on year. But if you’ve noticed uncomfortable symptoms after eating particular foods, it can be difficult to work out which condition you’re experiencing.  

So, allergy vs intolerance – what’s the difference? And how can you discover what’s causing your symptoms? In this blog post, we’ll explain the difference between an allergy and intolerance and how our tests can help you take control of your diet.

What is an allergy?

If you’re suffering from an allergy, it means your body experiences an allergic reaction in response to certain substances (known as allergens). Your immune system perceives the substance as a hazard and responds by releasing proteins called IgE immunoglobins.

These proteins increase your body’s secretion of histamines – a chemical that triggers an allergic reaction. This can result in symptoms such as vomiting, hives, swelling or itching.

An allergic response often starts a few minutes after you’ve eaten an allergen. However, in rare cases, it can take a couple of hours for your symptoms to appear.

What is an intolerance?

The main difference between an allergy vs an intolerance is the fact that an intolerance isn’t an immune response. If you’re intolerant to certain foods, it means that your body finds it difficult to break them down and digest them.

In response, your system releases a different type of immunoglobin known as IgG4. This can cause a range of uncomfortable symptoms, usually gastric issues such as bloating, nausea or diarrhoea.

There’s also evidence that certain intolerances can induce a range of other symptoms, including headaches and fatigue. Although research is ongoing, there also seems to be the link between gluten intolerance and inflammation.

Unlike allergies, intolerances are almost never life-threatening.

How do I find out which I have?

At Lifelab Testing, we offer a range of home allergy and intolerance tests. Our range of allergy tests will look for raised levels of IgE in your blood, while our intolerance tests will identify IgG4.

If you’re not sure whether you have an allergy or an intolerance, our complete body test can diagnose 40 different allergies and 80 intolerances. This test will search for both IgE and IgG4, arming you with the information you need to make confident decisions about your diet.

Eating disorders: The negative effects of an elimination diet

Since the start of the pandemic (Covid-19), we have seen how this challenging time is continually influencing our day-to-day life.  Recently on our previous blog, we have explained how symptoms for covid-19 and allergies can be easily misinterpreted, causing people fear and anxiety. Read more about the difference in symptoms here.

A recent work published on the International Journal of Eating Disorders showed how covid‐19 epidemic significantly impacted on eating disorders, both in terms of post‐traumatic symptomatology and interference with the recovery process(1).

Eating disorders are normally ‘hot topics’, especially for businesses that are working in the sector of health products and alternative tests. We have seen that recently there is also a lot of discussion about how food allergies and intolerances tests can be harmful to people with eating disorders due to the use of restriction diets.

As we are taking this really seriously and we are not afraid to talk about such topics, today we would like to update you on the new research in the field and show you how we are making sure that our tests and our messages are using in the right way to take care of you.

Recent international lab work has demonstrated the risk of developing an eating disorder following the prescription of a diet (which involves the elimination of several foods to reduce dyspeptic symptoms), seems particularly high in adolescents and young women who have a need to feel in control in life (e.g., feeling in control in various aspects life such as school, work, sports or other interests) (2). In this case, the restriction diet is seen as a successful behaviour of control in the context of perceived failure in other areas of life. In addition to that the number of people who call themselves “allergic to food” is on the rise; for the misuse of the term “allergic,” which leads to defining allergic the undesirable effects of drugs, toxic reactions to food, enzymatic deficits (e.g., lactase or sucrase-isomaltose deficiency) and vasomotor reactions to irritants (e.g., citrus or tomato) (3).

This research is showing us that we need to be careful when we are giving people information about the use of allergy and intolerance tests, especially in the case of people with previous eating disorders. Here at Lifelab Testing, we are making sure that our message is loud and clear:

  • Our tests are qualitative tests that can help you understand how your immune system is reacting to foods and environmental allergens. The test results can be considered as a map to take with you into your journey to find a better version of yourself. Before making any changes or take on restrictions it is always better to talk to your medical doctor and consider your medical history. Your doctor will be able to go through the results and combining your medical history, with your symptoms and our test results he will be able to suggest the best treatment.
  • We are helping our customers taking the first step through the consultation of a Nutritional Therapist. The Nutritional Therapist will collect as much information as possible before suggesting if an elimination diet could be used to help to manage some symptoms. The elimination diet is always followed by a reintroduction diet. Reintroducing those triggered foods will help understand how they are impacting your symptom, sometimes a reduction in the intake of foods can improve or eliminate some symptoms; this is the reason why we are never suggesting eliminating any food in your diet for a long period of time unless you suffer from severe reactions. Never take an elimination diet without the consultation of a qualified nutritional therapist or medical doctor. This can be dangerous for your health and your medical history is a big part in the diagnosis. Our job is to give our customers tools to help them put all the pieces together with the supervision of a qualified nutritional therapist or medical doctor.

Please be careful and take care during these challenging times. If you need any further help, please don’t hesitate to contact us or use specialised support out there. Remember we are in it together and we will get through together.

Covid-19 or Allergies: How can I distinguish the symptoms?

During this challenging time, with every sneeze, cough or tickle in the throat, many people wonder: Do I have COVID-19 or allergies? This could be a tricky question since most of those symptoms are also associated with seasonal flu. If this was not enough, millions of allergy sufferers around the world are finding this question tricky to answer, causing them to unnecessary self-isolate and constant worries: COVID-19 or allergies?

Today, we are here to shine some light on the recent findings to help you distinguish the symptoms between COVID-19 and allergies. If you think that you are experiencing COVID-19 symptoms, please call your local NHS practice and get tested for COVID-19 first.

Allergies can occur seasonally or be present year-long including mild to severe symptoms. Allergies are caused by your immune system overreacting to pollen, dust, mould, pet dander to mention some and are not contagious.

Common allergies symptoms include:

Sneezing, running nose, itchy or watery eyes, itchy nose or ears, mild fatigue, and mild sore throat.

The coronavirus (COVID-19) is a viral illness spread through droplets via coughing, sneezing, and close personal contact. Symptoms typically start between 2-14 days after exposure and they can be mild, moderate, or severe.

Common COVID-19 symptoms include:

Fever, dry cough, shortness of breath, intense fatigue, body aches, loss of smell.

How to distinguish between the two: Checklist for COVID 19 or Allergies
  • Allergies symptoms tend to be long-lasting than viral symptoms and can be treated with allergy medications

  • Itchiness is normally a clear symptom of allergy while is not a symptom of viral infection

  • Fever is not a symptom of allergy, but is a common symptom of people with COVID-19

  • Constant sneezing is associated with allergy symptoms.

To help you check the symptoms we are summarising the symptoms for COVID-19 and allergies in the table below so you could check your symptoms and help determine what health issue you may be suffering from. On our website, we have allergy and intolerance tests available that can help you to determine the cause of your symptoms. Please stay alert and keep safe, together we will get through that.
