Understanding Lab Tests for Allergic Diseases
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Allergic diseases encompass a wide range of conditions including asthma, atopic dermatitis, allergic rhinitis, food allergies, and environmental sensitivities. These conditions occur when the immune system overreacts to normally harmless substances called allergens. Blood tests play a crucial role in diagnosing allergic diseases and identifying specific triggers.
Recommended Test

How Blood Tests Diagnose Allergic Diseases
When exposed to allergens, the immune system produces specific antibodies called Immunoglobulin E (IgE). Blood tests can measure these IgE levels to confirm allergic reactions and identify the specific substances causing symptoms. This precise identification is essential for developing effective treatment plans and avoidance strategies.
Understanding Your Results
High IgE levels against specific allergens confirm allergic sensitization and help explain symptoms like sneezing, congestion, skin rashes, or breathing difficulties. Results guide healthcare providers in recommending appropriate treatments, environmental modifications, and allergen avoidance strategies tailored to your specific triggers.
