When reactions are frequent but their cause is unclear, guesswork rarely helps. This test measures IgE antibodies against roughly 295 individual allergens, covering the overwhelming majority of triggers seen in routine allergy testing. From grass and tree pollens to house dust mite, cat and dog dander, common foods, moulds and stinging-insect venoms, it builds a detailed map of what your immune system responds to.

The result is a clearer, more personalised picture than a short standard panel can offer, useful whether your symptoms are respiratory, skin-related or digestive. Your sample is a single venous draw, taken in our private Leigh-on-Sea clinic and analysed by an accredited UK laboratory, with a doctor-reviewed report returned within 5–7 working days.

A broad screen like this is a strong starting point rather than a final verdict. Your report highlights where antibodies were detected and how strongly, giving you and your GP or allergist a solid, evidence-based foundation for any dietary changes, avoidance strategies or further investigation that may be worth discussing.

Preparation: No fasting required. You can continue antihistamines if you need them, as this blood test measures IgE antibodies and is not affected by them. Note any current medication for your report.

About this test

  • Around 295, spanning inhaled allergens, foods, moulds, insect venoms and more, with a total IgE measurement included.

  • It shows which allergens your immune system has produced antibodies to, and how strongly. That is a powerful guide, but results are best read alongside your symptoms with a GP or allergist before making changes.

  • No. Because this is a blood test measuring IgE antibodies, antihistamines do not affect the result, so you can keep taking them as usual.
