The allergy service at Guy's Hospital is one of only 5 full-time allergy centres in the UK.

We are one of the busiest and largest allergy centres. We are recognised as a centre of excellence by the Department of Health.

We see mainly outpatients. We'll see patients who are on the wards.

Our service is provided by consultants. They have experience in:

  • allergy
  • immune system
  • respiratory (breathing) medicine

We also have:  

  • junior doctors
  • specialist NHS allergy nurses
  • an allergy dietitian


Your allergy drug and food challenges will take place in the allergy day care unit (ADCU).
