Description
Why It’s Done:
• To accurately diagnose allergic reactions to specific environmental or food allergens.
• To determine the cause of symptoms such as sneezing, nasal congestion, itchy eyes, wheezing, skin rashes, or anaphylaxis.
• To assist healthcare providers in developing personalized allergy treatment plans, including allergen avoidance strategies or immunotherapy.
• To evaluate the effectiveness of ongoing allergy treatments.
Preparation:
• For blood tests:
– No fasting is required.
– Continue medications unless advised otherwise.
• For skin tests:
– Avoid antihistamines for 3–7 days prior, as they can interfere with test results (consult your doctor for specifics).
– Inform your healthcare provider about any medications you are taking, including antihistamines, steroids, or asthma medications.
– Wear short sleeves or loose clothing if undergoing skin testing on the arms.
