Small drops of allergen extract are placed on your forearm and the surface of the skin is lightly pricked.
When an immediate IgE sensitivity is present, a small raised wheal usually appears within 15 to 20 minutes, so the results are read and explained during the same appointment.
Stop all antihistamines three days (72 hours) before skin prick testing so they do not suppress the skin reaction.

How a skin prick test works
Small drops of allergen extract are placed on your forearm and the surface of the skin is lightly pricked. When an immediate IgE sensitivity is present, a small raised wheal usually appears within 15 to 20 minutes, allowing Dr Pereira to read and explain your results during the same appointment.
The £450 fee includes Dr Pereira's consultation and up to eight allergens. Further allergens are £10 each, up to five more, and if you suspect a particular food or substance you may bring a sample to test in clinic.
A raised skin prick or blood IgE result shows sensitisation rather than a confirmed clinical allergy. Dr Pereira interprets every positive finding against your actual symptoms and reaction history before recommending avoidance or treatment.
Preparing for skin prick testing
Stop all antihistamines three days (72 hours) before skin prick testing so they do not suppress the skin reaction. If you cannot pause your tablets, a blood test is the better choice, because blood tests are not affected by antihistamines.
What to bring
- A list of your current tablets, inhalers and nasal sprays
- Copies of any previous NHS or private allergy test results
- Photographs on your phone of any rash, hives or swelling during a flare-up
- A small sample of a suspected food or substance
Skin prick test or allergy blood test?
Skin prick testing suits you when you can stop antihistamines and want an answer in the room. If you have several possible triggers or cannot stop antihistamines, the ALEX allergy test screens 290+ allergens from one blood sample for £413.75.
If you are unsure which test fits your symptoms, book the £250 consultation and decide with Dr Pereira in the room. All three routes, the targeted blood panels and treatment are set out on our private allergy testing in London page, and Dr Pereira also offers allergy testing for children.

“I recently had a blood test for rabbit allergies at Medical Express Clinic, and I'm extremely pleased with the service. Not only did I receive my results faster than expected, but the receptionist was fabulous, she answered all my questions and accommodated all my requests. It's the only walk-in clinic I found in central London with reasonable prices. Highly recommend this clinic!”
