The Accessible Intolerance Test

Allergy involves IgE‑mediated immune responses and can be life-threatening; intolerance is dose‑dependent, digestive and generally non‑life-threatening and may involve other immune pathways.

Blood-based tests involve analysing a blood sample to measure specific biological markers. These tests are typically interpreted by healthcare professionals as part of a broader medical assessment.

Bioresonance services use a non-invasive hair sample and are categorised within complementary and alternative wellness approaches. They are designed to provide informational insights that may support personal wellbeing reflection.

Neither service should be used as a substitute for professional medical advice, diagnosis, or treatment. If you have health concerns, you should consult a qualified healthcare professional.

Our tests are ideal for people who experience ongoing symptoms such as bloating, fatigue, headaches, skin issues, or digestive discomfort without a clear cause.

They’re also helpful if you suspect certain foods or environmental factors may be affecting your energy, mood, or overall wellness, but you can’t pinpoint which ones.

Testing provides personalised insights to guide smarter dietary and lifestyle choices.

No, our sensitivity tests are designed to be simple and non-invasive. Hair sample tests only require a few strands of hair, which can be gently plucked or trimmed close to the root. There’s no discomfort involved, and no needles or blood are required.

We only need a small sample — around 4 to 5 strands of hair, at least 4cm long. That’s about the thickness of a pencil lead, so you won’t notice a difference. The hair can come from your head or, if needed, another area of the body. Coloured or treated hair is fine.

Bioresonance intolerance tests Safe for children of any age, since only a small hair sample is required and the process is completely non-invasive.

Optimum nutrition during pregnancy and breastfeeding is vital for mother and child. To reduce any possible risk to the mother or baby, it is our protocol not to offer tests, advice or lifestyle changes during pregnancy and/or breastfeeding.

Allergy (IgE) tests Certain medications, such as antihistamines, steroids, or immunosuppressants, may impact results. Speak with your doctor before testing. Intolerance (IgG) tests Most medications do not affect results, though long-term immunosuppressive therapy or steroids may reduce antibody levels. Bioresonance intolerance tests Medications generally do not affect the analysis, since the test measures hair sample frequencies.

Once we’ve received your sample at our ISO accredited laboratory, you’ll receive your test results via email in just 3-5 working days.

You’ll receive an easy-to-read report via email, along with guidance and support on your next steps.

If you’ve ordered a Digital Test , there is no physical kit sent out .

Instead, you’ll receive a digital activation code by email , along with clear instructions and our lab address. Simply place a small hair sample into a grip-seal bag, pop it into a standard envelope, and post it to us using your preferred postal service.

If you’ve ordered a Physical Test Kit , this will be dispatched to you by post and will include everything you need, including a prepaid return envelope.

Why there’s no kit for Digital Tests

Our bioresonance testing doesn’t require specialist collection equipment, which allows us to offer a faster, more flexible, and eco-friendly option with no waiting for delivery.

📦 Eco-friendly by design This approach reduces packaging, courier journeys and waste — helping lower our overall carbon footprint while keeping results just as accurate.

Bioresonance Sensitivity Test (Hair analysis) Bioresonance testing looks at the energetic frequencies of a hair sample to identify potential imbalances. It does not measure immune antibodies or diagnose allergies. For this reason, a confirmed allergy may not appear in your bioresonance results. You should still avoid allergens identified by a medical professional, regardless of your sensitivity results.

Hair food sensitivity tests, also known as bioresonance intolerance tests, are designed as a wellness screening tool rather than a medical diagnostic. They analyse energetic responses from a small hair sample to highlight potential imbalances with foods, drinks, and environmental items. At Check My Body Health, our Food Intolerance Test is processed in an ISO 9001 accredited laboratory, ensuring consistent quality and reliability. While bioresonance is not medically approved or used in NHS diagnostics, many people find the results provide valuable, affordable insights into possible triggers for symptoms such as bloating, fatigue, and skin irritation. In summary: hair food intolerance tests are not a substitute for medical testing, but when carried out in a quality-assured lab, they can offer a cost-effective and trustworthy way to explore potential intolerances and guide lifestyle changes.

A food allergy and a food intolerance are not the same thing — they involve different parts of the immune system and cause very different reactions. Food Allergy • Involves the immune system producing IgE antibodies. • Reactions are usually immediate (within minutes to 2 hours). • Symptoms can include hives, swelling, difficulty breathing, or even anaphylaxis - a potentially life-threatening reaction. • Food allergies are less common but more serious and require medical diagnosis and management. Food Intolerance • Often linked to the immune system producing IgG antibodies. • Reactions are typically delayed (hours or even days after eating). • Symptoms are less severe but can still affect quality of life - such as bloating, fatigue, headaches, skin issues, or digestive discomfort. • Food intolerances are more common and can often be managed by adjusting your diet. In summary: • Food allergies (IgE) are immediate and can be dangerous. • Food intolerances (IgG) are delayed and less severe, but can still impact your health and well-being. If you suspect a food allergy, it’s important to speak with a healthcare professional immediately. Intolerance tests, on the other hand, can help identify foods that may be contributing to ongoing symptoms and guide dietary changes.
