Johnson Grass
Use
The Johnson Grass test is used to measure the levels of specific IgE antibodies against Johnson Grass allergens in a patient's serum. It is commonly used to aid in the diagnosis of allergic conditions such as hay fever or allergic asthma related to exposure to Johnson Grass pollen. Detecting specific IgE antibodies helps clinicians determine the presence of allergic sensitization and can guide patient management and treatment decisions.
Special Instructions

Limitations
The Johnson Grass test is specific to IgE antibodies and does not assess other types of immune responses or allergic mechanisms. It may not detect all possible allergies related to grass pollen. Results should be interpreted in the context of clinical evaluation and other diagnostic findings. The presence of specific IgE indicates sensitization, but not necessarily clinical allergy, and should be considered along with patient history and symptoms.
