Allergy Blood Test Results Explained: Demystifying the Numbers
Receiving the results of an allergy blood test can feel like deciphering a secret code, with numbers and units that seem foreign and confusing. However, understanding these results is crucial for managing allergies effectively. Let's break down the components of a typical allergy blood test report and shed light on what those numbers actually mean. Understanding IgE Levels : Allergy blood tests primarily focus on measuring Immunoglobulin E (IgE) antibodies, which are produced by the immune system in response to allergens. The report usually presents IgE levels in two ways: Total IgE : This number reflects the overall amount of IgE antibodies in your blood, measured in international units per milliliter (IU/mL). While a high total IgE level suggests an increased likelihood of allergies, it doesn't identify specific triggers. Specific IgE : This section lists individual allergens tested, alongside their corresponding IgE levels. These values are also measured in IU/mL and are c
