Understanding Lab Tests for Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Allergies occur when the immune system overreacts to normally harmless substances called allergens. While allergic reactions can often be observed through symptoms like sneezing, itching, or rashes, identifying the specific allergens responsible requires specialized blood testing.
Recommended Test
Respiratory Allergy Profile Region II: DC, DE, MD, NC, VA
This comprehensive test measures elevated levels of Immunoglobulin E (IgE) antibodies specific to common respiratory allergens in your geographic region. IgE is a type of antibody that is produced when the body reacts to an allergen, and elevated levels can indicate an allergic response to specific environmental triggers like pollen, mold, or dust mites.

How Blood Tests Diagnose Allergies
Blood tests for allergies measure Immunoglobulin E (IgE) antibodies, which are produced by the immune system in response to specific allergens. These tests can identify exactly which substances trigger your allergic reactions, enabling targeted avoidance strategies and appropriate treatment plans.
Benefits of Allergy Testing
Identifying your specific allergens through blood testing allows for more effective management of allergic reactions. This information helps healthcare providers develop personalized treatment plans, recommend appropriate medications, and provide guidance on allergen avoidance strategies to improve your quality of life.
