About this test

This test measures IgE antibodies to American cockroach, a year-round indoor allergen. Cockroach allergens are found in kitchens and apartment buildings. A positive result shows sensitization, which is not the same as an allergy. No fasting or other prep is needed.

For adults 18 and older. Test availability varies by lab location.

Who should take this test?

For adults with year-round congestion, or asthma that seems worse at home, who want to check for sensitization to American cockroach, often before seeing an allergist.

What does this test measure?

Your result shows whether your blood has IgE to American cockroach. With your history, it can help a healthcare provider understand whether sensitization may be part of your symptoms.

American cockroach-specific IgE (i206)
Specific IgE is an antibody the immune system can make against one allergen. This marker measures IgE that recognizes American cockroach. A level above the lab’s reference range shows sensitization, read with your symptoms and history.
Why it’s measured: Checks for IgE sensitization to American cockroach when symptoms are worse at home all year.

Not on its own. A positive result means your immune system has made IgE to American cockroach, which is called sensitization. Many people who are sensitized have no symptoms when they are exposed.

A diagnosis of allergy is made by a healthcare provider who looks at your symptoms and history along with results like this one. A negative result also does not by itself mean you are not allergic.

Cockroach allergens come from droppings, saliva, and shed body parts, which settle into household dust. They are found in kitchens and apartment buildings year-⁠round.

A positive result shows sensitization, not that cockroaches cause your symptoms. An allergist reads it with your history and where symptoms happen.

Both look for IgE sensitization. A skin test checks how your skin responds to a small amount of an allergen, while this test measures IgE to American cockroach in a blood sample. In many cases the two are considered comparable.

A blood test may be preferred in some situations, such as a widespread skin condition or recent use of medicines that affect skin tests. Don’t stop or change any medicine without talking with your healthcare provider.
