The Food & Drink Reactivity Test combines both IgE Allergy Testing and IgG Intolerance Testing to provide a comprehensive understanding of your body’s response to different foods and drinks.

Why test for both allergies and intolerances?

  • IgE Allergy Testing detects immediate immune responses to specific foods, which can result in symptoms like rashes, swelling, difficulty breathing, or digestive issues. These reactions typically occur within minutes or hours of consumption and may require medical attention.

  • IgG Intolerance Testing identifies delayed immune responses to foods, which can take hours or even days to appear. Intolerances are often associated with chronic or recurring symptoms such as bloating, headaches, fatigue, or joint pain.


By testing for both, this dual analysis provides a complete picture of your food reactivity, helping you identify not just severe allergies but also subtler intolerances that may impact your day-to-day well-being.

Common symptoms that may overlap

  • Digestive Issues: Bloating, constipation, diarrhoea, or stomach cramps.
  • Skin Reactions: Rashes, eczema, or hives.
  • Fatigue: Persistent tiredness or lack of energy.
  • Respiratory Problems: Sneezing, nasal congestion, or shortness of breath.
  • Headaches or Migraines: Recurring or unexplained.
  • Joint or Muscle Pain: Chronic aches without an obvious cause.

This mix of allergy and intolerance testing empowers you with knowledge about what your body thrives on and what it struggles with, helping you achieve optimal health.

Specific IgE blood testing is a clinically recognised method used by healthcare professionals, including within NHS allergy assessment pathways, to help investigate allergic sensitisation.

Sources:

Yes. Specific IgE blood testing is a clinically recognised method used within allergy assessment pathways. The NHS explains that allergy investigations may include blood testing, while NICE guidance recommends serum-specific IgE testing as one option when assessing suspected IgE-mediated allergies alongside clinical history.

Sources:

A specific IgE blood test measures allergen-specific Immunoglobulin E antibodies produced by the immune system. Measuring these antibodies can help identify sensitisation to particular allergens, such as foods, pollen, dust mites or animal allergens, when interpreted alongside symptoms and history.

Sources:

An IgE allergy blood test is a laboratory test that measures levels of allergen-specific Immunoglobulin E (IgE) antibodies in your blood. IgE antibodies are produced by your immune system when it reacts to substances known as allergens. Measuring specific IgE levels can help identify possible allergic sensitisation to triggers such as foods, pollen, dust mites, moulds and animal allergens. The Check My Body Health Premium Allergy Test uses advanced laboratory technology to measure specific IgE antibodies against 174 food and environmental allergens from one simple home blood sample. Your results should always be reviewed alongside your symptoms and medical history, which is why we include access to professional support to help you understand your results.

IgE (Immunoglobulin E) allergy testing is a clinically recognised method used to assess immune responses associated with allergic reactions.

By measuring allergen-specific IgE antibodies in the blood, testing can help identify potential food and environmental allergens that may be contributing to symptoms.

“Many people experiencing allergy-related symptoms know something feels ‘off’, but identifying what may be contributing to those reactions is not always straightforward.”

“Over the years, I’ve seen how frustrating it can be when symptoms continue without clear answers. Allergy testing can help provide greater clarity by looking at how the immune system may be responding to common food and environmental allergens.”

“Having a clearer understanding of potential triggers can help people feel more informed, more confident, and better supported in deciding their next steps.”

Understanding the differences between food reactions

Allergy, intolerance, and sensitivity are often used interchangeably — but they’re not the same. Each involves a different type of reaction in your body, and understanding the difference is key to managing your symptoms effectively.
Food allergy
Food intolerance
Sensitivities

Food allergy

Food allergies trigger an immediate immune reaction involving IgE antibodies. When someone eats a food they’re allergic to, their immune system releases histamine, which can cause symptoms like:

• Swelling
• Itching
• Hives
• Trouble breathing
• In severe cases, anaphylaxis

This is why many allergy medications are called antihistamines — they work by blocking the effects of histamine.

For example, tree nut allergies (to foods like hazelnuts, walnuts, or macadamia nuts) can cause severe, life-threatening reactions. Anaphylaxis can occur within minutes of exposure, potentially leading to a dangerous drop in blood pressure or airway swelling that makes it hard to breathe.

Food intolerance

Food intolerances trigger a different kind of immune response than food allergies.

Although the exact science isn’t fully understood, research suggests that IgG antibody reactions may play a role in symptoms for some people. When combined with an elimination diet, IgG testing can help identify foods that may be causing inflammation-related issues.

Unlike allergies, which cause immediate reactions, symptoms of food intolerances often show up hours or even days later — making it much harder to connect the dots without testing.

Common symptoms reported by our customers include:

• Headaches
• Bloating
• Stomach pain
• Indigestion
• Gastrointestinal discomfort

Sensitivities

Food sensitivities happen when your body struggles to process certain foods, often because they are difficult to break down in the digestive system.

Unlike food allergies or intolerances, sensitivities don’t involve the immune system. Instead, they mainly affect how well your digestive system can handle specific foods.

A common example is caffeine sensitivity.

Caffeine is found in coffee, tea, and energy drinks. Some people break it down more slowly, which can lead to symptoms such as:

• Jitters or restlessness
• Rapid heartbeat
• Trouble sleeping
• Stomach discomfort

While food sensitivities aren’t typically dangerous, they can still cause significant discomfort and affect your daily wellbeing if left unmanaged.
