Rye Grass, Perennial

This test measures the level of specific antibodies in your blood that react to pollen from perennial rye grass. It helps show whether your immune system treats this common grass as a harmful invader, which is useful for investigating symptoms like sneezing, itchy eyes, or asthma. By identifying this specific sensitivity, the test helps distinguish grass allergies from other environmental triggers like mold or pet dander. However, a positive result does not predict exactly how severe your physical reaction will be when you are exposed to the grass.
