The Goosefoot Allergy Test is a blood test that looks for an allergic response to goosefoot, a common weed pollen also known as lamb's quarters. It is usually ordered when someone has seasonal allergy symptoms and a clinician wants to identify whether goosefoot pollen is a trigger.

What it measures

  • Goosefoot-specific IgE — An antibody tied to allergic reactions to goosefoot pollen; higher levels suggest sensitization.
  • Total IgE — A general measure of allergic antibody in the blood, sometimes included for context.
  • Other weed or grass pollens — May be tested together to see whether symptoms come from more than one pollen.
  • Cross-reactive foods — Occasionally checked because some plant pollens share proteins with certain foods.

Who it is for

A primary care clinician, allergist, or immunologist typically orders this test. It is most often used for people with recurring sneezing, runny nose, itchy eyes, or wheezing during pollen seasons.

Preparation

No fasting is required, and the blood draw can be done at any time of day. Tell the lab about any allergy medications you take, since some may affect results.

Results and what they mean

Results are reported as antibody levels, often with a reference range or class score. A clinician interprets them alongside your symptoms and history, because a positive result alone does not always mean you have symptoms. This is general information, not medical advice; discuss your results with a qualified clinician.

Frequently asked questions

Does a high result mean I am allergic to goosefoot?

It means your blood shows sensitization to goosefoot pollen. Whether that causes symptoms depends on your history and exposure, so a clinician interprets it with your symptoms.

Do I need to stop my allergy medicine before this test?

Usually not for a blood test, but some medications can affect results. Ask your clinician or the lab before stopping anything.

How long does it take to get results?

Typical turnaround is 1 to 3 business days after the sample reaches the lab.

Is this test painful or risky?

It uses a standard blood draw, which causes brief discomfort. Risks are minor and similar to any routine blood test.
