About Johnson Grass Allergy Test | Grass Pollen in Gresham
Johnson grass is a warm-season perennial grass that produces light, wind-borne pollen. Because the pollen is small and easily dispersed, it can be inhaled and trigger allergic symptoms in sensitized individuals.
The test works by detecting immunoglobulin E, or IgE, the antibody class associated with immediate allergic reactions. A blood sample is drawn and analyzed for IgE that binds specifically to Johnson grass pollen proteins.
Elevated specific IgE suggests that the immune system has been sensitized to Johnson grass pollen. Sensitization does not always equal symptoms, so results are interpreted alongside a person's history and other clinical findings.
Grass pollens share some overlapping proteins, so a positive result to Johnson grass may also reflect cross-reactivity with other grasses. A healthcare professional can help interpret the findings in context.
