Allergy Diagnostic Testing
Your physician will ask detailed questions about signs and symptoms of allergies, perform a physical exam, and possibly have you keep a detailed diary of symptoms and possible triggers.
If you have a food allergy, your doctor will likely ask you to keep a detailed diary of the foods you eat.
Your doctor might also recommend a skin test or blood test to evaluate for allergies. A skin test involves will prick your skin and inject a very small amounts of the proteins found in potential allergens. If you’re allergic, you’ll likely develop a raised bump (hive) at the test location on your skin. A blood test, Specific IgE (sIgE) blood testing, commonly called radioallergosorbent test (RAST) or ImmunoCAP testing, measures the amount of allergy-causing antibodies in your bloodstream, known as immunoglobulin E (IgE) antibodies. A blood sample is sent to a medical laboratory, where it is tested for evidence of sensitivity to possible allergens.
