Modern Concept of Molecular Diagnostics of Allergy to Dogs

The number of people suffering from allergies is increasing worldwide every year. With the prevalence of domestic animals, especially dogs, allergens associated with them can be found ubiquitously, thereby increasing the risk of anaphylaxis in sensitized individuals. Currently, there are 8 known dog allergens, but not all of them have been thoroughly studied. The commonly used skin prick tests often fall short and fail to provide a comprehensive assessment of a patient's condition, thus making allergy diagnosis challenging. Fortunately, the introduction of new allergy diagnostic methods has made it possible to accurately identify clinically significant allergens for patients. These findings can then be used to prescribe appropriate therapy or provide specific recommendations to the patients. This review focuses on the most important dog allergens and modern allergy diagnostic techniques that are gradually being incorporated into medical practice, thus expanding the capabilities of allergists.
