Private Allergy Testing London

Skin Prick Testing or Skin Allergy Test Clinic

At Walk in Clinic, our team provides private allergy testing for babies, children and adults. We prefer commonly used and scientifically accepted Skin Prick Test (SPT) methods used in the UK for diagnosing inhalant, environmental and food allergies.

We use Skin Prick Test solutions or allergens for performing the tests. Our extensive range of common allergens Prick-to-Prick skin tests take samples from the foods that might you might be allergic to. Bring the sample with you for testing at our clinic.

Whether you or your child is suffering from some kind of allergy, it is advised to visit the private allergy clinic in London where the doctors will diagnose and confirm the infection.


The most important aspect of allergy diagnosis is careful clinical examination by a specialist supplemented with thorough investigations to include the following:

  • Skin prick tests that can be performed in our out-patient department with same day results
  • Allergy blood tests, carried out in the outpatient department. Our on-site pathology laboratory ensures quick turnaround of results within 48 hrs.
  • Challenge tests with foods or drugs from our consultants who can give advice on managing the allergy
  • Food symptoms - food diaries will be given by our specialists

It is important to emphasise that conducting tests without a detailed specialist allergy consultation can be confusing.

Some Common Allergy Testing at Our Clinic:

Skin Prick Test

A skin prick test is about pricking your skin, inserting a small amount of substance and waiting to see what happens next. This safe and quick method involves minimal pain and the effective result can be seen after a twenty minutes. Some drops of allergen extract prepared in the laboratory can be applied on the skin and punctured lightly with a shallow lancet. We perform skin prick allergy testing at our clinic located in Harley Street at affordable prices.

If IgE antibodies are present, a welt or wheal with a diameter of around 5 to 15 mm will appear. Wheals will then disappear within a period of 30 minutes to an hour. There is small chance that the patient might develop a strong reaction, however, the patient’s are usually monitored closely and appropriate treatment given where necessary.


At Walk in Clinic, we conduct different tests such as – a positive control, negative control and 8 selected antigens in the form of primary skin prick testing protocol. The initial testing costs start from £150, with room to add up almost 5 more antigens for £10 per antigen.

Provocation Tests

If there are differences between the results of allergy tests and medical records, then you may need a provocation test. The allergen will be presented to the patient under monitored conditions. Based on the allergen and several symptoms it may cause, you might breathe in the allergen in small yet increasing doses or place it on the lower lip or inside the mouth, apply it to the conjunctiva or sniff. Examples, where this testing is required, will help to reveal if a child has a peanut allergy or if an antibiotic is taken safely when different tests are not yet clear.
