Abstract:
Allergic diseases are common in outpatient primary care. Allergy testing can guide management to determine allergy as a cause of symptoms and target therapeutic interventions. This article provides a review of common methods of allergy testing available so that physicians may counsel and refer patients appropriately. Immediate-type hypersensitivity skin tests can be used for airborne allergens, foods, insect stings, and penicillin. Radioallergosorbent testing can be used to evaluate immediate-type hypersensitivity. Delayed-type hypersensitivity or patch-type skin tests are used in patients with suspected contact dermatitis.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibodies consist of four polypeptide chains: two identical heavy...
