# Thistle, Russian

> This test measures the amount of specific IgE antibodies in your blood that react to Russian Thistle, a common weed often known as tumbleweed. It helps show whether your immune system treats this plant's pollen as a harmful invader, which can explain symptoms like sneezing, a runny nose, or itchy eyes. By identifying this specific sensitivity, the test helps distinguish a Russian Thistle allergy from reactions to other plants or environmental irritants. However, this test cannot determine exactly how severe your symptoms will be during exposure or diagnose an allergy without a doctor's review of your medical history.
