Alex food intolerance and allergy testing
The Alex (Allergy Explorer) test is a state-of-the-art diagnostic tool that screens for nearly 300 allergens simultaneously. Using advanced molecular technology, it provides an unparalleled level of detail, identifying specific IgE responses to foods, pollens, and environmental triggers to help you manage complex sensitivities with precision.
Alex food intolerance and allergy testing
The gold standard in comprehensive molecular allergy profiling
Traditional allergy tests often focus on a limited range of triggers. The Alex test uses macro-array technology to provide a "360-degree" view of your immune system's sensitivities, allowing our clinicians to distinguish between true allergies and cross-reactivities, ultimately leading to a more accurate and personalised management plan.
