Common Pigweed details

Common pigweed is a widespread weed that releases pollen in late summer, contributing to fall seasonal allergies. This test measures IgE antibodies specific to pigweed pollen to check for allergic sensitization, which can cause symptoms like sneezing, nasal congestion, and itchy or watery eyes during its pollen season. It's typically included as part of a regional weed allergen panel alongside other common late-season weeds, since weed pollen allergies frequently involve sensitivity to multiple related species. A positive result reflects sensitization and is interpreted together with your symptom history.
