Western Ragweed (w2) IgE details
What Western Ragweed (w2) IgE shows
Western ragweed is a weed that grows across the western and central United States, and like other ragweeds it releases large amounts of pollen from late summer into autumn. This test measures IgE antibodies specific to western ragweed pollen to check for allergic sensitization. It can help explain sneezing, a runny nose, itchy eyes or asthma that flare during late summer and fall. A positive result shows sensitization, not necessarily allergy, and needs to be matched against when your symptoms occur. Ragweed species cross-react strongly, so it is usually interpreted alongside short and giant ragweed results.
