Our Services

Allergy Testing

The allergy testing our service offers is for people with suspected allergic rhinitis (hay fever), asthma and eczema. Testing includes house dust mite, animal dander, mould spores, pollen from relevant grasses, weeds or trees and in some cases, occupational allergens. Testing can also be used to confirm suspected allergies to foods.

Patch Testing

Patch testing is useful to test for allergic contact dermatitis, that may be triggered by metal, cosmetic/industry preservatives. It involves applying patches with test substances in small chambers, with hypoallergenic adhesive to the back. Results are interpreted at 48 & 72hrs.

Skin Prick Testing

Is the most convenient and accurate method of allergy testing. the results are available within 20 minutes and allows for same day discussion of outcomes and treatment options available.

Skin prick tests are commonly performed on the forearm or back. The skin is assessed prior to
the testing. The area is marked with corresponding numbers to allergens used. Using a sterile plastic lancet, a small prick is made which allows a drop of allergen to be introduced into the skin. If you are allergic to the tested allergen, a small itchy lump (wheal) surrounded by a red flare will appear within 15-20 minutes. The test is slightly uncomfortable but is usually well tolerated in all age groups.

Allergen Immunotherapy

Allergen Immunotherapy (AIT) changes the way the immune system reacts to allergens, by switching off the allergy. AIT involves regular administration of gradually increasing doses of allergen extracts, compounded specifically to each individual, usually over a period of 3-5 years. This results in tolerance to allergens, with fewer or no symptoms. Three years of AIT can result in 5-10 years of benefit and then symptoms may start to return after that time.

AIT for aeroallergens can be given by regular injection (subcutaneous), or by daily oral doses (sublingual). It generally takes 4-6 months for symptoms to improve. Allergy medications can still be used to help manage symptoms while undergoing AIT.

It is not recommended to start SIT treatment if already pregnant or planning pregnancy. Treatment can be started if breastfeeding. AIT is not normally started on children less than five years of age.
