iGP's ALEX³ Allergy test is a comprehensive, next-generation blood test that analyses up to 300 Allergens and total IgE from a single blood sample. The test identifies specific allergen components to distinguish genuine sensitisations from cross-reactivity. It screens for hundreds of common allergens, including foods, pollens, animals, dust mites, moulds, and other environmental triggers. This test is ideal for anyone experiencing ongoing allergy symptoms, as it provides clear, detailed results to help guide treatment, avoidance strategies, and further clinical advice.
Appointment Information: The ALEX³ test only requires a small blood sample, which is collected by an iGP nurse. The sample is then sent to our lab for processing.
