The immunology department provides a service for the diagnosis and management of many allergic conditions including:
We are able to perform:
-
skin prick tests and intradermal tests
-
specific IgE measurement (the antibody Immunoglobulin E)
-
supervised food or drug challenges.
We provide an immunotherapy (desensitisation) clinic and are able to undertake both subcutaneous and sublingual desensitisation therapy. There is specialist nursing support to provide patient and carer training in the recognition and management of anaphylaxis, and allergen avoidance.
Patient assessment and investigation
We aim to complete investigation and management plans for most new patients within a single appointment. Some patients may need to return for further clinical assessment or investigations. New patients are given a 30 minute appointment slot, during which time skin prick tests may be undertaken.
In general, patients should expect to be in the department for one hour at most. Where possible, patients should discontinue anti-histamines for five days before their appointment at a clinic. Patients should not stop asthma treatment or other medications without advice from their GP.
A note on stopping anti-histamines
Skin prick test are the most commonly performed test in our clinic for the investigation of allergic disease. The test relies on the ability of the skin to react to an allergen pricked into the top layer of the skin. Anti-histamines (and drugs with anti-histaminic effects such as tricyclic anti-depressants and some older anti-psychotics) will suppress the skin reaction.
We generally request that anti-histamines are discontinued for five days before clinic attendance, where possible. Some people with very severe symptoms may find it difficult to stop the anti-histamines and in that situation blood tests may be performed. These blood results, however, may not be available for some days to weeks.
It is not necessary to stop other medication (eg, asthma pumps, nasal sprays). Do not stop anti-depressants or anti-psychotics without the advice of your doctor.
