Description
Why It’s Done:
• To diagnose allergy to Johnson grass pollen in people experiencing seasonal allergy symptoms like sneezing, nasal congestion, itchy eyes, coughing, or asthma, especially during grass pollen seasons.
• To identify environmental allergens responsible for respiratory allergies or hay fever.
• To help guide allergy management strategies including avoidance and immunotherapy.
• To evaluate allergic triggers in both children and adults.
Preparation:
• For blood testing:
– No fasting or special preparation is needed.
– Continue medications unless your healthcare provider advises otherwise.
• For skin testing:
– Avoid antihistamines for 3 to 7 days prior to the test as they can affect results (consult your doctor).
– Inform your healthcare provider about all medications you are taking.
– Wear clothing that allows easy access to the skin (e.g., short sleeves).
