Johnson Grass

This test measures the level of specific antibodies in your blood that react to Johnson Grass pollen. It helps show whether your immune system treats this grass as a threat, which is useful for investigating symptoms like sneezing, runny nose, or itchy eyes. This testing helps identify if Johnson Grass is a specific trigger for your seasonal allergies compared to other plants. However, the test cannot determine exactly how severe a future allergic reaction will be or diagnose an allergy without a doctor reviewing your symptoms.
