Allergy Testing/Treatment Q & A

by Adel Zakhary, MD

What are Allergies?

Allergies are a response of the immune system which occurs when a substance in the environment known as an allergen gets into contact with a person either through inhaling it, swallowing it, or touching it. When an allergen makes contact the person has an abnormal or excited immune response. Allergies often cause symptoms such as:

  • Itchy, watery eyes
  • Rashes
  • Feeling tired or ill
  • Hives
  • Sneezing
  • Itchy, runny nose
  • Coughing

Food and insect allergies can cause other symptoms such as vomiting, cramps, local swelling, and pain.

What Tests Are Used to Diagnose Allergies?

To determine what a person is allergic to and how to treat the symptoms, the doctor will ask questions about the symptoms being experienced and what types of allergens the person could be in contact with. Allergy skin tests and blood tests are used to diagnose the allergy. During an allergy skin test, the doctor will use concentrated extracts of certain allergens to test for a reaction on the skin such as a rash. When the reaction is present the doctor knows that the person is allergic to that substance. The substance can be made to react with the person’s skin by pricking the top layer of skin, injecting a small amount under the skin, or placing a treated patch on the skin. When a food allergy is a concern, it is important for patients to try to identify what they ate which could have caused the reaction. This helps the doctor direct the tests. The allergy causing food usually has to be avoided.

What Treatments are Available?

Frequently, medications are available over-the-counter to help with mild allergies. When the allergy symptoms are more severe, the doctor can prescribe other types of medications to help address the issue including:

  • Antihistamines and decongestants- these medications can help with the nasal symptoms of allergies such as itching, sneezing, and congestion.
  • Nasal sprays- when congestion is particularly severe these sprays can help to clear nasal passages
  • Eye Drops- different forms of drops can be used to help treat itchy, red, and watery allergy eyes
  • Allergy Shots- these injections can help when the symptoms are severe by working with the body to control the immune response
