  1. What is Allergen Testing?<\/b><\/span><\/li>\n<\/ol>\n

    Allergens<\/b> are external substances that induce immune-mediated hypersensitivity reactions, commonly referred to as <\/span>allergic reactions<\/b>. These may occur rapidly with severe acute manifestations such as anaphylaxis, or as prolonged conditions including urticaria and eczema.<\/span><\/span><\/p>\n

    In Vietnam, approximately <\/span>20% of the population suffers from allergic diseases<\/b>, with the highest prevalence among individuals aged 12\u201315 years. The incidence is higher in urban areas compared to rural regions (National Hospital of Dermatology and Venereology) [1].<\/span><\/span><\/p>\n

    \"\"<\/a><\/span><\/p>\n

    Allergen testing<\/b> plays a crucial role in identifying the specific causative allergens responsible for these reactions. It not only supports the confirmation of allergic conditions but also helps differentiate allergies from other disorders with similar clinical symptoms.<\/span><\/span><\/p>\n

    Common Methods of Allergen Testing:<\/b><\/span><\/p>\n

    1.a. SPT – Skin Prick Test<\/b><\/span><\/p>\n

    Mechanism<\/b>: A drop of allergen extract is applied to the skin (forearm, upper arm, or back), followed by a gentle prick to allow penetration. Multiple allergens can be tested simultaneously, alongside positive (histamine) and negative (saline\/glycerin) controls. Results are evaluated after 15\u201320 minutes by measuring wheal and erythema [2][3].<\/span><\/span><\/p>\n
