Allergies have become a common health concern affecting millions of people worldwide. An allergy is an exaggerated immune response to substances that are generally harmless, known as allergens. These allergens can trigger a range of symptoms, from mild discomfort to severe and life-threatening reactions. Identifying specific allergens in an individual is crucial for effective diagnosis and management. Allergen immunoassays play a pivotal role in this process, providing a reliable method for detecting and quantifying allergen-specific antibodies in patient samples.
