Blood Tests for Allergy

Why Do I Need an Allergy Blood Test?

Allergists have many tests to determine if a patient is suffering from an allergy or not. One of the tests performed could be an allergy blood test. When a skin test cannot be performed due to medications, or it is inconclusive, an allergy blood test may be able to determine what is causing a specific allergic reaction.


A blood test for allergies measures immunoglobulin E antibodies in relation to a specific allergen. An allergy blood test may also determine an absolute eosinophil count, which measures the number of white blood cells that become active during an allergic reaction. A blood test for allergies is best interpreted by an allergy specialist.
