Understanding Sensitivities and Intolerances

Sensitivities and intolerances to certain substances can cause a variety of symptoms that may interfere with daily routines. Unlike allergies, which prompt an immediate immune system response, sensitivities typically develop gradually and are often influenced by diet, environmental factors, and everyday habits.

Common signs that may indicate a sensitivity include:

  • Bloating, gas, or irregular digestion
  • Itchy or irritated skin, redness, or mild rashes
  • Headaches or recurring migraines
  • Persistent fatigue or low energy levels
  • Mild joint pain, swelling, or stiffness

Identifying what’s triggering these symptoms is an important step toward improving how you feel. With accurate testing and expert support, it's easier to uncover the root causes and take steps to reduce discomfort and enhance overall well-being.

Our Optimum Health Test offers a comprehensive analysis, assessing your body’s responses to more than 1,400 food and non-food substances. This in-depth test helps uncover possible triggers so you can make confident and informed lifestyle changes.

At Test Your Intolerance, our expert lab technicians are qualified in bioresonance testing and have been specialising in hair analysis since 2008. As industry leaders, we've conducted over 1,000,000 tests for clients worldwide.

We’re proud to offer the Optimum Health Test, the most extensive panel available on the market today.

By identifying substances that may be contributing to unwanted symptoms, you can take control of your health through smarter dietary and lifestyle choices, leading to reduced discomfort and improved overall well-being.

What's tested

We analyse your body’s sensitivity responses to 1,400 items using a simple hair strand sample.

Our comprehensive test covers a wide range of areas, including:

  • Food & Drink
  • Environmental Sensitivities
  • Metal Toxicity
  • Nutritional Factors (Vitamins & Minerals)
  • Digestive Health
  • Metabolic Function
  • Anti-Ageing Markers
  • Skin Health
  • Stress & Inflammation

Using advanced bioresonance technology in our ISO-accredited laboratory, each item is tested and assessed for reactivity.

Every item is then categorised into one of three reactivity levels, helping you better understand 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.
