Quick answer
The Johnson Grass Allergy Test checks for IgE antibodies against pollen from Sorghum halepense, a tall grass often found along roadsides and in fields. Its pollen is released in warm months and can contribute to seasonal allergic rhinitis. The test helps determine whether someone with summer or early fall symptoms has become sensitized to this particular grass.
What this test measures
Johnson grass is a perennial grass that grows in many warm and temperate regions. It pollinates in summer and can produce large amounts of lightweight pollen that travels in the air. Grass pollen is a common trigger for seasonal allergies.
The test measures specific IgE antibodies to Johnson grass pollen from a blood sample. A positive result indicates sensitization. Because grasses share some proteins, people may react to more than one grass, and a positive result is often assessed alongside other grass tests.
Testing may be ordered when symptoms such as sneezing, itchy eyes, or wheezing occur during grass pollen seasons, or when a clinician wants to identify which grasses are contributing. A qualified healthcare provider should interpret the result with the seasonal history.
