It is a fast, non-invasive way to identify sensitivities to up to 900 food and non-food items, including allergens, nutritional deficiencies, metal toxicity, gut biome imbalances, and hormonal disruptions. Using advanced bio-resonance technology, this test requires only a small hair sample, making it easy and painless to complete from home. Unlike blood or urine tests, hair analysis provides a long-term health snapshot, unaffected by diet or stress. With results available in just 3 to 5 days, you’ll receive a detailed, easy-to-read report highlighting key sensitivities and personalised insights.

GetTested offers blood-based food intolerance tests to help identify sensitivities to common foods that may be causing digestive issues, skin reactions, fatigue, or other symptoms. Using the scientifically validated ELISA method, these tests measure IgG4 antibodies to detect delayed food reactions that can be difficult to pinpoint. With options ranging from 40 to 240 tested foods, as well as combined allergy and intolerance testing, GetTested provides comprehensive insights to help you make informed dietary choices and improve your overall well-being—all from the convenience of a home test kit.

GetTested offers a range of allergy tests designed to help individuals identify and manage their allergic reactions with ease. From quick at-home rapid IgE tests that deliver results in just 10 minutes to comprehensive lab-based tests analysing up to 90 allergens, GetTested provides reliable options for every need. Whether you're looking to pinpoint specific allergies to pollen, pets, or foods, or need a broad assessment covering multiple allergens, these tests offer accurate insights analysed in ISO-certified laboratories. With convenient home sample collection and expert-backed results, GetTested makes it simple to take control of your allergies and improve your well-being.

Commonly, people confuse these two conditions. Lactose intolerance is related to the body's reaction to milk sugar, while cow's milk allergy involves an immune response to milk proteins.
Cow’s milk allergy, like other food allergies, happens because the immune system overreacts to cow’s milk. This means that drinking cow’s milk can trigger an allergic reaction. Some of the symptoms of Cow’s milk allergy are similar to the symptoms of Lactose Intolerance, as both can cause digestive problems. However, cow’s milk allergy can also cause symptoms such as skin rash, swelling of the lips, face or skin around the eyes or a runny nose. Cow’s milk allergy is most common in young children. Usually they grow out of it.

Unexplained fatigue, digestive discomfort, brain fog, skin irritation, or low mood? These symptoms are often written off as “normal,” but they can be signs your body is reacting to something in your diet or environment. Unlike allergies, food and environmental intolerances often trigger delayed, low-grade immune responses that can go unnoticed for years—quietly affecting your energy, gut health, and overall well-being.
At Gut Resonance, we’ve curated a selection of trusted intolerance testing options from GetTested and EasyDNA, so you can choose the approach that’s right for your lifestyle, symptoms, and level of detail.
Not sure where to start? Here's how the tests compare:
EasyDNA Intolerance Test uses a small hair sample to evaluate your response to over 900 food and non-food items, including household products, pet dander, pollens, and more. It also includes assessments for:
Nutritional deficiencies
Metal sensitivities
Gut biome balance
Hormonal imbalances
This test is perfect if you're looking for a non-invasive, holistic overview of your sensitivities and how they relate to your wider health picture.
GetTested Food Intolerance Tests use a blood sample (via finger prick) to detect IgG4 immune reactions to foods. Choose from:
A focused 40-item panel for common triggers
A broader 80-item panel
A deep-dive 240-item analysis for complex or persistent symptoms
Or a combined Allergy & Intolerance Test for IgE and IgG4 reactions, helping you distinguish between immediate allergies and delayed sensitivities.
These tests are ideal if you're experiencing symptoms like bloating, fatigue, skin issues, or neurological complaints—and want precise, immune-based results with lab-grade accuracy.
Whether you’re dealing with long-standing digestive issues, trying to optimise your energy, or simply seeking clarity on what your body can and can’t tolerate, our testing options provide the insight you need to make informed, health-affirming changes.
Take the guesswork out of your diet and start listening to your body—accurately, gently, and from the comfort of your home.

Allergy Tests – Understand Your Body’s Reactions
Allergies can affect everything from your breathing to your skin, digestion, and overall energy—but identifying the cause isn’t always straightforward. At Gut Resonance, we offer a range of at-home allergy tests by GetTested to help you uncover what your immune system is reacting to.
Whether you’re struggling with seasonal hay fever, pet dander sensitivity, or suspect certain foods might be the trigger, these easy-to-use tests measure IgE antibody responses to common allergens. Choose from rapid screens to in-depth lab panels, and take the first step toward targeted relief and greater clarity about your body’s needs.
Lactose & Gluten - Intolerance and Allergy Tests
Digestive discomfort, skin flare-ups, bloating, or fatigue after meals? These symptoms are often linked to common dietary triggers—especially dairy and gluten—but understanding whether you're dealing with an allergy, intolerance, or sensitivity is key to finding lasting relief.
At Gut Resonance, we offer three targeted testing options to help you uncover the root of your symptoms:
Gluten Intolerance Test
Detects IgG antibodies to transglutaminase, helping identify gluten sensitivity or potential coeliac disease. Ideal for symptoms like bloating, fatigue, and brain fog after eating gluten-containing foods.Lactose Intolerance Test
Combines breath hydrogen/methane analysis with genetic testing to assess your ability to digest lactose (milk sugar). Perfect for those experiencing bloating, gas, or diarrhoea after dairy, without signs of immune reaction.Allergy Profile X – Milk & Gluten
A lab-based IgE allergy test for true immune reactions to multiple milk proteins and gluten. Suitable for those with immediate symptoms like rashes, swelling, or respiratory discomfort.
Each test offers a different lens into how your body responds to food—whether it’s enzyme-related, immune-driven, or autoimmune in nature. If you're unsure whether your reaction is caused by intolerance or allergy, or want to rule out coeliac markers, this section will help you explore the right path forward.
