About this test

This blood test measures IgE antibodies to Ficus species, the weeping fig houseplant. It is a year-round indoor allergen that can cross-react with latex. People often check it for indoor symptoms that last all year. A positive result shows sensitization, not necessarily an allergy.

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

Who should take this test?

For adults whose year-round sneezing, congestion, or itchy eyes seem worse indoors, especially around houseplants, who want to check for sensitization to ficus.

What does this test measure?

Your result shows whether your blood has IgE to ficus. With your history, it can help a healthcare provider understand whether this houseplant may be part of your indoor symptoms.

Ficus (weeping fig)-specific IgE
Specific IgE is an antibody the immune system can make against one allergen. This marker measures IgE that recognizes Ficus species, the weeping fig houseplant, a year-round indoor allergen. A level above the lab’s reference range shows sensitization.
Why it’s measured: Checks for IgE sensitization to ficus when indoor symptoms last all year.

It can. Ficus, the weeping fig houseplant, is a year-⁠round indoor allergen, so symptoms may not line up with a pollen season.

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

It can. Ficus can cross-⁠react with natural rubber latex, and with fig, the fruit. People sensitized to one can show IgE to the others.

An allergist reads these results together with your history. Decisions about latex exposure or eating fig belong with your allergist.

Not on its own. A positive result means your immune system has made IgE to ficus, 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.
