About Johnson Grass Allergy Test | Grass Pollen in Lafayette
Johnson grass is a tall, perennial grass that produces abundant pollen, a frequent trigger of seasonal allergic rhinitis.
Johnson grass (Sorghum halepense) releases lightweight pollen grains that can travel long distances in the air. For sensitized individuals, exposure to this pollen may lead to sneezing, nasal congestion, itchy or watery eyes, and other typical allergy symptoms.
The test detects specific IgE antibodies in the blood. When the immune system has previously recognized Johnson grass pollen as an allergen, it produces these antibodies, which can be measured to support a diagnosis of grass pollen allergy.
Results are typically reported as a quantitative value or a class score. A positive result indicates sensitization to Johnson grass pollen, but it should be interpreted alongside clinical history and other findings by a qualified healthcare provider.
