Skin prick testing (SPT) is a primary mode of testing to diagnose IgE-mediated allergic disease in patients with rhinoconjunctivitis, asthma, anaphylaxis, and suspected food and drug allergy. It provides evidence for sensitisation and can help to confirm the diagnosis of a suspected type 1 allergy.
Skin Prick Testing is widely practiced, carries a very low risk of side-effects and provides high-quality information when performed optimally and interpreted correctly*.
Small amounts of allergen extracts are introduced into the epidermis and interact with specific IgE bound to cutaneous mast cells. Histamine and other mediators are released, leading to a visible “wheal-and-flare” reaction (except to the negative control) after about 15 minutes.
Skin prick testing should be used to confirm the diagnosis of allergy when taken in conjunction with the patients’ history and clinical examination. It differentiates allergic diseases from other mimicking conditions. It may lead to allergen avoidance strategies, improved use of medications, and for some patients, Immunotherapy.

20% of the UK’s population suffers from seasonal allergic rhinitis triggered by tree pollen and grass pollen during spring and summer.Types of allergies
Most allergic rhinitis patients can control their condition with over-the-counter medicine such as antihistamines and prescription steroids. These come as tablets, nasal sprays and eye drops. But when it’s so severe that conventional treatments don’t work, your patient may be at risk of developing more serious health problems like asthma. For these people, immunotherapy may be the only solution.Treatment
