Detailed explanation-1: -Type I hypersensitivity is also known as an immediate reaction and involves immunoglobulin E (IgE) mediated release of antibodies against the soluble antigen.

Detailed explanation-2: -An allergy blood test measures a substance called immunoglobulin E (IgE) in your blood. IgE is an antibody that your body makes. If you have allergies, you may have more IgE in your blood than normal. Allergies are a common, long-term condition that involves your immune system.

Detailed explanation-3: -Immunoglobulin E (IgE) plays a critical role in the allergic inflammatory process in diseases such as allergic rhinitis. Cross-linking IgE bound to its receptor on cells by multivalent allergens initiates a chain of events resulting in allergic immune responses.

Detailed explanation-4: -Immunoglobulin E is one of the five classes of immunoglobulins (IgM, IgG, IgD, IgA, IgE). IgE has a unique chemical structure and an array of physiological functions, such as Type I hypersensitivity reactions, parasitic infections, autoimmune processes, and venom protection.
