Understanding Sensitivities and Intolerances

Sensitivities and intolerances to certain substances can lead to a broad range of symptoms that may interfere with everyday life. Unlike allergies, which produce an immediate immune reaction, sensitivities tend to develop gradually over time and are influenced by factors like nutrition, environment, and daily habits.

Common signs of sensitivities may include:

  • Digestive discomfort such as bloating, gas, or irregular bowel movements
  • Skin issues like itchiness, redness, or rashes
  • Headaches, including tension headaches or migraines
  • Ongoing fatigue or low energy
  • Mild joint pain, stiffness, or swelling

Addressing these symptoms becomes more manageable with the help of focused testing and professional insight, making it easier to identify triggers and find effective relief.

Our Standard Sensitivity Test offers a comprehensive analysis, examining how your body reacts to more than 500 different food and non-food substances. This can help you identify possible triggers and make confident, informed changes to your daily routine.

At Test Your Intolerance, our experienced lab team consists of qualified bioresonance technicians who have been specialising in hair testing since 2008. As a trusted industry leader, we’ve completed over 1,000,000 tests for clients across the globe.

By pinpointing which items may be contributing to unwanted symptoms, you can take proactive steps in your diet and lifestyle to help alleviate discomfort and support your overall well-being.

What's tested

We analyse your body’s sensitivity responses to 500 different items using a non-invasive hair strand sample.

This test covers key areas, including:

  • Food & Drink
  • Environmental Sensitivities
  • Metal Toxicity
  • Nutritional Factors (including Vitamins & Minerals)

Each of the 500 items is tested for reactivity levels in our lab using advanced bioresonance technology.

The results are then categorised into three reactivity levels, giving you clear insights into how your body may be responding to specific substances.

High Reactivity

Displayed in red. These items are the most likely to be contributing to sensitivity-related symptoms. We recommend starting with a structured elimination diet to remove these triggers, followed by a gradual reintroduction process to monitor your body’s response.

Moderate Reactivity

Displayed in amber. These items may cause sensitivity. Consuming multiple moderately reactive items together could lead to symptoms because of their combined effects. After completing the elimination of high-reactivity items, we recommend following a structured elimination diet for these items as well, followed by a gradual reintroduction to monitor your body’s response.

No Reactivity / within range

These items are considered safe and fall within the optimal range. They will not be included in your report.

Many customers commonly call this a “food intolerance test,” but it actually measures sensitivity responses, providing a more comprehensive view of how your body reacts over time.
