Allergy or Intolerance Testing

Many people in the UK are affected by allergy and/or intolerance to certain foods and other allergens.

You may experience problems when you eat certain foods or when exposed to other ‘allergens’ in the environment such as pollen, dust mites, animals and insect venom.

With many symptoms related to allergy and intolerance, it is very difficult to know what you might be allergic to, or if it’s a food, whether you have an intolerance instead.

We also offer very specific tests e.g. nut allergy, penicillin allergy and more.

Book a consultation with one of our clinicians in our clinic in the centre of Winchester.

 

Book an Allergy or Intolerance Consultation

The first step to knowing what is going on is to book a consultation with one of the REMEDI HEALTH clinicians.

By taking a full history and understanding your symptoms, your clinician can help with testing options. After listening to your symptoms and history, your clinician will help you choose an appropriate test or, in some instances, a test may not be required.

Choose whether it’s better for you to have this in our clinic or remotely, either by phone or video consultation, then select a date and time from the calendar, enter your details and confirm what your consultation is for. You will need to come into the clinic if a blood draw is required.

  • Allergy consultation £60
  • Food intolerance laboratory fee £225
  • Full allergy profile £345
  • Specific allergy testing e.g. nuts, penicillin £POA

Testing for allergy or intolerance

Your blood is analysed to detect your body’s reaction to 295 allergen extracts and allergen components. Alternatively we can perform a food intolerance test to over 200 food and drink ingredients. Junior intolerance tests are also available.

About this service

Your clinician takes a comprehensive health history including your symptoms, how long they have been present, the impact they have and how they change. You will also be asked about your health history, any other conditions, medications and family history. Your diet and social habits will also be discussed.

Once we have a good picture of your health, we can suggest the most appropriate test and solutions. In some instances testing will not be necessary or we may think something else is going on that needs further investigation.

What is an Allergy?

Allergy is an overreaction of your immune system in response to something that is normally harmless. In an allergic reaction to substances such as pollen, house dust mites, medicines, certain foods or insect stings, the immune system produces antibodies called Immunoglobulin E (IgE) specific to the allergen it’s trying to fight. The process of your body becoming sensitive to an allergen is called sensitisation.

When you have an allergic reaction, the IgE antibodies tell other cells to release certain chemicals, such as histamine. And it’s those chemicals that can cause the annoying and sometimes even life-threatening allergy symptoms. 

What is an Intolerance?

Food intolerances can take some time to diagnose. Although not life threatening, food intolerance can and often does, make the sufferer feel extremely unwell and can have a major impact on working and social life.

Intolerance to foods can occur at any age and can result in a range of symptoms which are generally delayed by up to 72 hours after eating.

There are many possible symptoms that could be caused by having an intolerance to food. The type of food that is suspected depends on the possible range of symptoms. These symptoms may also be experienced in other conditions in the absence of food being a problem, so should always be discussed with a health professional. Symptoms commonly affect the digestive, skin and respiratory systems.  

Skin symptoms may include flushing of the skin, urticaria (raised red, itchy rash), eczema flares or angioedema (deep swelling of the tissue). Digestive symptoms can include abdominal pain, diarrhoea, bloating, stomach cramps, and constipation. The respiratory (breathing) system can also be affected rhinitis, breathing difficulties and a wheeze. Other symptoms include headaches and palpitations.  

It is important to understand the difference between a food allergy and food intolerance but also to understand which particular condition is causing your problems. With food intolerance the person may be able to tolerate a small amount of the food before they experience symptoms.  

Those with an immediate food allergy will have to strictly avoid the food(s) especially those with immediate type (IgE mediated) food allergy as these are associated with the risk of a severe allergic reaction (anaphylaxis), which is a medical emergency. 

Food allergies happen when the immune system mistakenly recognises a food as harmful and an allergic response and symptoms are seen. Food intolerances are caused by a substance within the food itself or by the body which has problems with digesting that food (such as lactose intolerance due to a lack of the lactase enzyme, whose job it is to break down the lactose in foods).  

 

Different types of intolerance

Lactose intolerance happens when there are reduced levels of the enzyme lactase in the digestive system needed to break down the ‘sugar’ founds in cow’s milk or where there has been a gastrointestinal infection which results in a reduction of the lactase enzyme levels (secondary lactose intolerance). Lactose found in cow’s milk and other dairy produce including cheese and yoghurt.  

Gluten intolerance gluten is a mixture of proteins found in foods like wheat, barley and rye. Gluten can be found in foods like bread, biscuits, crackers, pasta and cakes. Some people with a gluten intolerance may also need to avoid oats because of contamination issues.  

Non Coeliac gluten sensitivity is a mild form of gluten intolerance the exact role of the immune system in non-coeliac gluten sensitivity is unclear and further research is needed.  

Food additives and food chemicals It is possible to have reactions to naturally occurring substances or those added as a preservative in food including: 

  • Benzoates (Benzoic acid) are produced by many plants and have also been detected in animals, they are found in foods like berries and milk. Benzoates are added to foods like soft drinks, jams, pickles sweets and chocolates. 
  • Caffeine is a well-known stimulant, it occurs naturally in plants and is mainly used in drinks such as tea, coffee, and energy drinks and can also be found in chocolate. 
  • Alcohol (ethanol) is an organic substance and is mainly consumed in alcoholic drinks such as wine, beer or spirits.  
  • Monosodium Glutamate (MSG) commonly are naturally occurring in ripening fruits and cured meats. Also commonly added to savoury food.  
  • Salicylates are a group of naturally occurring chemicals that are produced by plants as a defence against things such as diseases, insects and bacteria. Foods containing salicylates include fruits, vegetables, herbs and spices. Manufactured (synthetic) salicylates are used in aspirin and other non-steroidal anti-inflammatory (NSAID’S) medication.  
  • Sulphur dioxide (sulphites) is often in cider, wine, beer and dried fruits. Sensitivity to sulphites mainly affects patients with asthma, especially those with severe steroid-dependant asthma.  
  • Vaso active amines (including Histamine) are produced by bacteria during fermentation, storage or decay. They are found in foods like cured meats, fruit, vegetables and fermented soy products, green tea, coffee, champagne, wine, beer, and fresh fruit juice.  
Allergy testing

The Allergy blood test enables the analysis of 290+ allergens using the innovative technology ALEX – Allergy Explorer. ALEX measures allergen specific IgE and total IgE. The allergens that are tested are divided into the following groups:

  • Pollen 59
  • Pets 25
  • Mites 19
  • Insect stings 10
  • Moulds & yeasts 13
  • Foods 154
  • Other allergens 14

We take a simple venous blood draw or for children can use a fingerprick sample.

The blood sample is sent to a specialist laboratory and analysed. 

The test detects your body’s reactions to both allergen extracts and allergen components, allowing for comprehensive precision testing right down to individual proteins in an allergen source. A comprehensive report is generated and shared with you once the results are available.

The test results are usually back within a day or so.

Intolerance testing

Take our most comprehensive food and drink intolerance test to find out whether you have an intolerance to 200 food and drink ingredients.

This test is performed by our clinician by taking a finger-prick blood sample and sending to a specialist lab for testing.

Receive your results within 7 days. 

The test measures all four subtypes of food-specific IgG (1-4) compared to some which test only for IgG4. This is important as it ensures all of the different food-specific IgG reactions are detected.

Junior food intolerance test is also available for children aged 2 years and over.
