Tests and treatment for allergies and asthma

​Our consultant allergists are leaders in their field, offering diagnosis and treatment for both adults and children


An allergy is an overreaction of the immune system to a normally harmless substance, such as foods, pollen, cats or dust. This is known as an allergen. The body's immune system treats the allergen as an invader and reacts, resulting in allergy symptoms that can be anywhere from annoying to harmful. Symptoms could includes sneezes and itches, rashes, falls in blood pressure and airway narrowing, which leads to difficulty breathing. Over 18 million people in the UK have an allergy. Our consultant allergists test, diagnose and create treatment plans for many common allergies, including asthma, hay fever and allergic rhinitis, food allergies, reactions to medication, skin allergies, severe reactions to insect stings and more.


We have a comprehensive team of consultant allergists for both adults and paediatrics, together with access to up-to-date diagnostic allergy tests.

    Need to know

    A food challenge is considered the 'gold standard' diagnostic test for food allergies. It is the only true way of knowing whether your child will have an allergic reaction to a food. These tests are also useful to check whether a child has outgrown their allergy to a certain food or medicine.
