Used in clinical and research laboratories to measure levels of immunoglobulin E (IgE) in human biological samples, typically serum or plasma. This kit is essential for studying allergic responses, as IgE plays a central role in hypersensitivity reactions such as asthma, hay fever, and food allergies. It enables accurate quantification of total IgE or allergen-specific IgE, supporting diagnosis of allergic diseases and monitoring immune system activity. Widely applied in immunology research, drug development for allergy treatments, and epidemiological studies assessing allergy prevalence. The assay is reliable, sensitive, and suitable for high-throughput screening.
