What This Test Measures

The test detects the presence of antibodies (IgE) against a mix of common allergens, including airborne substances like pollen, dust mites, pet dander, mold spores, and certain foods. This helps determine if your immune system is reacting to these triggers.

Why It’s Ordered

Your healthcare provider may recommend this test if you experience symptoms such as sneezing, rash, hives, or difficulty breathing after exposure to suspected allergens, or if you have persistent allergic conditions like hay fever or asthma.

Sample Collection

A blood sample is drawn from a vein in your arm. The blood is processed to separate serum or plasma, which is then tested for allergen-specific antibodies.

Common Allergens Detected

This panel typically includes allergens such as grass pollen, tree pollen, house dust mite, cat or dog dander, mold spores, and common food allergens (e.g., peanuts, milk, eggs). Results help pinpoint specific triggers in your environment or diet.
