Quick answer
The Goosefoot Allergy Test detects IgE antibodies against pollen from Chenopodium album, a weed known as lamb's quarters, goosefoot, or pigweed. It grows in gardens, farm fields, and disturbed ground, and its pollen is released in summer and early fall. The test helps determine whether sensitization to this weed contributes to seasonal allergy symptoms.
What this test measures
Chenopodium album is a fast-growing annual weed found in many temperate regions. It is related to plants such as quinoa and amaranth. Its lightweight pollen is released in late summer and early fall and can travel long distances in the air.
The test measures specific IgE antibodies to Chenopodium album pollen in a blood sample. A positive result indicates sensitization. Weed pollens can overlap in season, so results are often interpreted along with other weed and grass pollen tests. This helps clarify which pollens are contributing.
Testing may be ordered when sneezing, a runny nose, itchy eyes, or asthma-like symptoms appear during the weed pollen season. A qualified healthcare provider should interpret the result and consider other seasonal allergens. A symptom diary that notes when symptoms occur can be helpful.
- Goosefoot (Chenopodium album) pollen-specific IgE antibodies
- Quantitative sIgE concentration reported in kU/L
- Allergen-specific IgE class on a graded scale
- Total serum IgE when included
- Blood eosinophil count when included
- Related weed or amaranth pollen markers when a panel is included
Why people order this test
- Evaluate late summer and early fall seasonal symptoms
- Assess sensitization to a common weed pollen
- Help separate weed pollen triggers from grass and tree pollens
- Add objective information to a seasonal allergy evaluation
- Check a specific weed when a broad panel is not needed
- Provide context for symptoms near gardens or farm fields
How to prepare
No fasting is required for this blood test. Follow the collection instructions provided by the laboratory, and note the months when symptoms occur so the pattern can be compared with the weed pollen season.
Understanding your results
Results are usually available within one to three business days. A detectable level indicates sensitization to Chenopodium album pollen, though symptoms depend on exposure and other sensitivities. A qualified healthcare provider should interpret the findings.

Frequently Asked Questions
What is lamb's quarters?
Lamb's quarters is a common name for Chenopodium album, a fast-growing weed also known as goosefoot or pigweed.
When does it release pollen?
The plant typically releases pollen in late summer and early fall, with timing varying by region and weather.
Is goosefoot related to quinoa?
Yes. Chenopodium album is in the same plant family as quinoa and amaranth, which is why cross-reactive sensitization is possible.
Can this pollen cause asthma symptoms?
Pollen sensitization can be associated with asthma-like symptoms in some people. A healthcare provider can evaluate whether it is contributing.
Can I react to other weeds too?
Yes. Many weed pollens overlap in season, and panels often test several to identify the main triggers.
