What is an Allergy?

An allergy is a response within the body to a substance (allergen) from its surroundings. This might be due to something that you eat, touch or inhale.

Any substance can cause allergies and it is difficult for individuals to detect the root cause of the problem. If you or your child has a suspected allergy, visit our private allergy clinic in London for the solution.

The skin prick test denotes if and what you are allergic to, avoid allergen and promote a better quality of life. It is a safe test and can be done in children and adults. It is not painful as a small metal pricker just scratches the upper layer of the skin with a drop of allergen.

If you are suspecting a severe allergic reaction, skin testing is a suitable way to know the root cause behind it. Some extracts of common allergens like pollen, mold, dust mites, animal dander, and foods are used to perform the tests. Once they enter the skin, they may trigger rash and make you feel irritated.

The kind of allergy test to conduct depend on your symptoms and allergists tell which tests to perform.

Different Kinds Of Allergens

Allergens are substances that can lead to an allergic reaction. You will find three kinds of allergens and they are the following:

  • Inhaled allergens – This may affect your body when they get in contact with the membranes or lungs of the throat or nostrils. Pollen is the most popular inhaled allergen.
  • Ingested allergens – They are usually present in certain foods such as – seafood, soy and peanuts.
  • Contact allergens – They should come in contact with the skin to produce some reaction. An example of a reaction from contact allergen is the rash and itching from poison ivy.

Common symptoms of Allergic Reaction include the following:

  • Asthma
  • Eczema
  • Rhinitis
  • Migraines
  • Itchy eyes, ears, throat, mouth or lips
  • Runny nose
  • Sickness, vomiting or diarrhoea
  • Sinus pain
  • Rash/Hives (Urticaria)
  • Swelling
  • Wheezing
  • Hyperactivity

Diagnosis of Allergy

At Medical Express Clinic, our doctors are helping to find out the exact origin of your allergy symptoms whether acute or severe. During your initial consultation, a complete history of allergic symptoms will need to be established by the allergy consultants, including allergies that you may have had as a child. After a full consultation, together with your specialist, both of you can decide upon the best treatment options which may include:

  • Patch test for contact allergies.
  • Skin prick test.
  • Challenge test which is undertaken in the hospital.

A blood test or skin test that results in some sensitivity may not necessarily an allergy. Together with your doctor, we will find out the exact cause of an allergy and devise the most appropriate management strategy. This can help to identify the specific substances you are allergic to and prevent restrictive diets. As an example, identifying dust mites to be the root cause of your child’s asthma can inform patients to undertake the appropriate interventions to improve the overall quality of life.

Our Allergy Testing Procedure:

Skin Prick Test

It is very safe and can be done in adults, children and even very small babies. It is not painful as a small metal pricker just scratches the upper layer of the skin with a drop of allergen. Little drops of allergen extract that are prepared in the laboratory are applied to your skin and punctured lightly by a shallow lancet. We perform skin prick allergy testing in London within our CQC registered clinic on Harley Street at an affordable price.

If there are IgE antibodies, a wheal or welt having a diameter of 5 to 15 mm will appear. The wheals will disappear within 30 minutes to an hour. There is a nominal chance that the patient might develop a strong reaction, however, patients are monitored closely and appropriate treatment is always provided at the point of reaction.


At Medical Express Clinic we do 10 tests – a positive control, negative control and 8 selected antigens as the primary skin prick testing protocol. The cost of testing including consultation costs £400, with room to add up to 5 more antigens for £10 per antigen.
