During allergy skin tests, your skin is exposed to suspected allergy-causing substances (allergens) and is then observed for signs of an allergic reaction.
Along with your medical history, allergy tests may be able to confirm whether or not a particular substance you touch, breathe or eat is causing symptoms. This procedure takes about 20 – 60 minutes to be completed.
Doctors may order allergy skin tests if you have:
• Hay fever (allergic rhinitis) and asthma symptoms that are not well controlled with medicine
• Hives and angioedema
• Food allergies
• Skin rashes (dermatitis), in which the skin becomes red, sore, or swollen after contact with the substance
• Penicillin allergy
• Venom allergy
