诊断。
Your doctor can diagnose allergies or you may be referred to a doctor that specializes in allergies. An allergist can perform tests to find out what you are allergic to and how severe your allergic reaction is. The doctor will make several minor scratches on your skin and apply a small sample of a possible allergen. If you are allergic to the allergen, your skin will react to form a small itchy red bump. 你的血液可能会被检测抗体.
