Allergy Testing in London

At London GP Clinic, we offer fast and reliable allergy blood testing to help identify substances that may be triggering your symptoms. If you are unsure which allergy test or panel is most suitable for your health concerns, we recommend discussing it with your GP.

Our clinic provides a range of advanced blood tests, including:

• Individual Allergy Blood Tests (IgE) – starting from £48
• ALEX Allergy Test – a comprehensive test covering hundreds of allergens, priced at £380
• Specialised Allergy Panels – tailored options for environmental, food, or combined allergens

What to Expect During Allergy Testing

Your initial consultation includes a medical history review to help identify potential allergens. If blood testing is recommended, a sample will be taken during your visit and analysed by our accredited laboratory.

Most allergy blood test results are available within a few days, after which we will send them to you securely — you can then review the results and discuss any treatment options with your GP.

Understanding Allergies

Allergies occur when the immune system overreacts to certain substances, known as allergens. These can include pollen, pet dander, insect venom, specific foods (such as peanuts, eggs, dairy), medications, and more. Reactions can range from mild discomfort to serious, life-threatening situations.

Common Allergy Symptoms

• Migraines or sinus pain
• Runny or blocked nose
• Asthma symptoms, wheezing, or breathing difficulties
• Vomiting or diarrhoea
• Skin rashes, hives, or eczema flare-ups
• Swelling of lips, eyes, or throat
• Itchy eyes, throat, lips, ears, or mouth
