Component-resolved diagnosis of allergy is a method of diagnosing allergies by targeting specific components within an allergen. This technique allows for a more precise and accurate diagnosis of the allergen causing the symptoms, as opposed to more traditional methods that identify only the type of allergen. There are several synonyms for this term, including molecular allergy diagnosis, microarray-based allergy diagnosis, and allergen component testing. Each of these terms emphasizes the specificity and precision of this diagnostic approach and highlights the importance of identifying the specific components of an allergen that trigger a patient's specific symptoms.
