Understanding Lab Tests for Allergic Disease
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Allergic diseases encompass a range of conditions where the immune system overreacts to normally harmless substances called allergens. These reactions can affect the respiratory system, skin, digestive tract, and other organs, causing symptoms like sneezing, itching, hives, or difficulty breathing.
Recommended Test
Respiratory Allergy Profile Region XVIII: Alaska
This comprehensive test measures Immunoglobulin E (IgE) levels specific to common respiratory allergens found in the Alaska region. Elevated IgE levels indicate an allergic response to various airborne substances such as pollens, molds, and other environmental allergens that can cause symptoms like sneezing, congestion, and breathing difficulties.

How Blood Tests Diagnose Allergic Diseases
Blood tests are a primary diagnostic tool for identifying allergic diseases. They work by measuring specific antibodies, particularly Immunoglobulin E (IgE), that the immune system produces in response to allergens. These tests can pinpoint exactly which substances trigger allergic reactions, enabling targeted treatment and avoidance strategies.
Understanding Your Results
Elevated IgE levels in response to specific allergens confirm the presence of allergic sensitivities. Your healthcare provider will interpret these results alongside your symptoms and medical history to develop an appropriate treatment plan, which may include allergen avoidance, medications, or immunotherapy.
