These terms are often confused, but they describe very different reactions in the body:

Food Allergy
• Involves the immune system producing IgE antibodies.
• Reactions are usually immediate (minutes to 2 hours).
• Symptoms can include hives, swelling, difficulty breathing, or even anaphylaxis, which can be life-threatening.
• Food allergies can only be confirmed with a blood sample (IgE testing) or a skin prick test performed by a medical professional.

Food Intolerance
• Linked to the immune system producing IgG antibodies.
• Reactions are delayed, often showing up hours or even days later.
• Symptoms are less severe but can include bloating, fatigue, headaches, skin issues, and digestive discomfort.
• IgG intolerance testing can help identify potential trigger foods to guide dietary adjustments.

Food Sensitivity
• A broader term often used for non-allergic, non-IgG responses.
• Can include reactions to foods, drinks, or environmental factors (like pollen, pet dander, or chemicals).
• Symptoms can overlap with intolerances, making them difficult to pinpoint without testing.
• Bioresonance sensitivity testing (hair analysis) provides insights into potential sensitivities and imbalances, supporting wellness choices.

In summary:
• Allergies (IgE) are immediate and can be dangerous.
• Intolerances (IgG) are delayed and affect well-being.
• Sensitivities (often non-food) are broader and may be linked to environmental or lifestyle triggers.

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 personalized insights to guide smarter dietary and lifestyle choices.

The main difference is in how the tests work and what they measure:

Blood-based intolerance tests (IgG) measure actual antibody levels in your blood, providing a clinical analysis of how your immune system responds to specific foods. They are scientifically validated and give precise insights into delayed food reactions.

Bioresonance sensitivity tests (hair analysis) use a non-invasive method to analyze the energetic frequencies of a hair sample. This approach can highlight a broader range of potential sensitivities — including foods, drinks, and environmental factors — but it is not a medical diagnostic tool.

Many people choose blood testing for a more clinical, science-based assessment, while bioresonance offers a holistic wellness perspective that can complement lifestyle and dietary improvements.

Our tests are designed to be simple and minimally invasive:

Blood tests
You’ll use a small, single-use lancet to collect a few drops of blood from your fingertip. Most people describe it as a quick pinch that’s over in seconds.

Bioresonance sensitivity tests
These are completely pain-free, requiring only a small hair sample that you can cut at home.

We only need a small sample — around 4 to 5 strands of hair, at least 1 inch 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. Colored or treated hair is fine.

Blood tests (IgG or IgE)
Suitable for children aged 2 years and older. Under age 2, the immune system is still developing, which may affect test accuracy. Parents should always assist with collection, and consult a pediatrician if their child has existing allergies or health concerns.

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

Blood tests (IgG or IgE)
We don’t recommend them during pregnancy or breastfeeding because immune responses and antibody levels can fluctuate, which may affect results. It’s usually best to wait until after this period.

Bioresonance sensitivity tests
These are safe during pregnancy, as they are non-invasive and require only a hair sample. However, always check with your healthcare provider before making significant dietary changes while pregnant.

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 sensitivity tests
Medications generally do not affect the analysis, since the test measures hair sample frequencies.

Once we’ve received your sample at our CLIA-certified 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.

Blood-Based Intolerance & Allergy Test Kits
Once your order is confirmed, your kit is shipped via a tracked courier service. Delivery usually takes 2–3 business days. Each kit contains everything you need to collect your blood sample at home, plus a prepaid return envelope to send it straight back to our CLIA certified laboratory.

Bioresonance Sensitivity Tests (Hair Analysis)
With bioresonance tests, there is no physical kit sent out. Instead, you’ll receive a unique digital activation code along with our lab address. Simply place a small hair sample into a grip-seal bag, pop it into a standard envelope, and mail it back using your preferred postal service.

📦 Eco-Friendly:
Our bioresonance process is faster, saves packaging, reduces courier deliveries, and lowers our carbon footprint — making it the most sustainable way to test.

As soon as your sample arrives at our lab, we’ll confirm receipt by email and SMS so you know it’s safely in processing.

Please be aware that different methods of post can take different lead times to arrive. USPS delivery times for addresses within the U.S. vary by shipping service, from overnight with Priority Mail Express, to over 5 days with Parcel Select Ground.
