# Ragweed, Western

> This test measures the level of specific antibodies in your blood that react to pollen from Western Ragweed. It helps show whether your immune system identifies this plant as a threat, which is useful for investigating the cause of seasonal symptoms like sneezing, a runny nose, or itchy eyes. By identifying a specific sensitivity, this test helps rule out other environmental triggers or non-allergic causes of congestion. However, this test cannot diagnose an active allergy on its own, as some people have antibodies without experiencing physical symptoms.
