12. **Patch Test**: - A patch test is a method of allergy testing used to identify contact allergens that cause allergic skin reactions. Small amounts of allergens are applied to patches and placed on the skin to assess if there is an allergic response.

13. **Allergen Extract**: - An allergen extract is a concentrated form of an allergen used in allergy testing to trigger an allergic reaction in individuals who are allergic to that specific substance.

14. **Histamine Release Test**: - The histamine release test is a laboratory test that measures the release of histamine from white blood cells when exposed to allergens. It is used to assess allergic reactions and diagnose allergic conditions.

15. **Challenge Test**: - A challenge test involves exposing an individual to a suspected allergen in a controlled setting to observe if it triggers an allergic reaction. This test helps confirm or rule out specific allergens causing symptoms.

16. **Provocation Test**: - A provocation test is a diagnostic test where an allergen is deliberately introduced to the body to provoke an allergic reaction. This test is performed under medical supervision to assess allergic sensitivities.

17. **Allergist**: - An allergist is a healthcare professional specializing in the diagnosis and treatment of allergic conditions. Allergists are trained to perform allergy testing, interpret test results, and develop treatment plans for allergies.

18. **Immunoglobulin E (IgE)**: - Immunoglobulin E (IgE) is a type of antibody produced by the immune system in response to allergens. Elevated levels of IgE in the blood indicate an allergic reaction to specific allergens.

19. **Allergic Rhinitis**: - Allergic rhinitis, also known as hay fever, is an allergic condition characterized by inflammation of the nasal passages in response to allergens such as pollen, dust mites, or pet dander.

20. **Atopy**: - Atopy refers to a genetic predisposition to develop allergic reactions to common allergens. Individuals with atopy are more likely to have allergies, asthma, or eczema.

21. **Anaphylaxis**: - Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen. Symptoms of anaphylaxis include difficulty breathing, swelling, and a drop in blood pressure.

22. **Cross-Reactivity**: - Cross-reactivity occurs when the immune system reacts to similar proteins in different allergens. For example, individuals allergic to birch pollen may also experience allergic reactions to certain fruits due to cross-reactivity.

23. **Eosinophil**: - Eosinophils are a type of white blood cell involved in allergic reactions and inflammation. Elevated levels of eosinophils in the blood or tissues can indicate an allergic response.

24. **Desensitization Therapy**: - Desensitization therapy, also known as immunotherapy, is a treatment for allergies that involves exposing the individual to increasing doses of allergens to build tolerance and reduce allergic symptoms over time.

25. **Sublingual Immunotherapy (SLIT)**: - Sublingual immunotherapy (SLIT) is a form of allergy treatment where allergen extracts are placed under the tongue to desensitize the individual to specific allergens. SLIT is a convenient and non-invasive alternative to traditional allergy shots.

26. **Inhalant Allergens**: - Inhalant allergens are allergens that are inhaled through the air and can trigger allergic reactions in the respiratory system. Common inhalant allergens include pollen, mold spores, dust mites, and pet dander.

27. **Food Allergens**: - Food allergens are substances found in certain foods that can trigger allergic reactions in susceptible individuals. Common food allergens include peanuts, tree nuts, shellfish, milk, eggs, and soy.

28. **Contact Allergens**: - Contact allergens are substances that cause allergic reactions when they come into direct contact with the skin or mucous membranes. Examples of contact allergens include latex, nickel, and certain cosmetics.

29. **Immediate Hypersensitivity**: - Immediate hypersensitivity, also known as type I hypersensitivity, is a rapid allergic reaction that occurs within minutes of exposure to an allergen. Symptoms can range from mild itching to severe anaphylaxis.

30. **Delayed Hypersensitivity**: - Delayed hypersensitivity, also known as type IV hypersensitivity, is a delayed allergic reaction that typically occurs hours to days after exposure to an allergen. This type of reaction is mediated by T cells and can result in skin inflammation or contact dermatitis.
