Allergies, also known as allergic diseases, are various conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis.
Allergen. An allergen is a type of antigen that produces an abnormally vigorous immune response in which the immune system fights off a perceived threat that would otherwise be harmless to the body. Such reactions are called allergies . In technical terms, an allergen is an antigen that is capable of stimulating a type-I hypersensitivity ...
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to antigen. [1] [2] It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity. It is caused by many types of particles and ...
Allergic rhinitis, of which the seasonal type is called hay fever, is a type of inflammation in the nose that occurs when the immune system overreacts to allergens in the air. [6] Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. [1] The fluid from the nose is usually clear. [2]
Type I hypersensitivity (or immediate hypersensitivity ), in the Gell and Coombs classification of allergic reactions, is an allergic reaction provoked by re-exposure to a specific type of antigen referred to as an allergen. [1] Type I is distinct from type II, type III and type IV hypersensitivities.
In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate). If 100 patients known to have a disease were tested, and 43 test positive, then the test has ...
An array of chemical allergens to be used in testing. Synonyms. Skin prick test. Purpose. Diagnosis of skin allergies. Skin allergy testing comprises a range of methods for medical diagnosis of allergies that attempts to provoke a small, controlled, allergic response.
A food allergy is an abnormal immune response to food. The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure. This typically occurs within minutes to several hours of exposure.
Blood test. For an allergy blood test, a sample of the patient's blood is sent to a laboratory for analysis. Allergy blood tests measure the presence of IgE antibodies to specific foods, pollens, mites, animals, insects and other environmental factors. (IgE, short for "immunoglobulin E", is the antibody that triggers food allergy symptoms.)
Signs and symptoms. Atopic sensitization is considered IgE positivity or prick test positivity to any common food- or air-borne allergen. [9] Atopic conditions are considered: atopic dermatitis, allergic rhinitis (hay fever), allergic asthma, atopic keratoconjunctivitis. The likelihood of having asthma, rhinitis and atopic dermatitis together ...
