    When to Get an Allergy Test for Your Child

    Does your kid get a runny nose during pollen season or hives after eating certain foods? It could be time for allergy testing.

    Your child's doctor may first tell you to try allergy medicine, but he may suggest seeing an allergist if it doesn't work and your kid has any of these problems:

    An allergist is a doctor who specializes in the diagnosis and treatment of allergies. When he sees your child, he'll:

    He'll also ask about your family history. If both parents have allergies, a child has a 75% chance of having them. If one parent has allergies, a kid has a 50% chance of having them.

    The allergist may suggest skin or blood tests that can check what kind of allergy your little one has. Your child may react to a skin test in just a few minutes, but blood tests take a few days.

    If the allergist thinks your child has a food allergy, he may also suggest a type of test called an "elimination diet." Your kid stops eating certain foods -- like milk, eggs, and peanuts -- to see if they were the cause of his allergy symptoms.

    Once the doctor's got all the test results, he'll develop a treatment plan for your child.

    One word of caution, though. Allergy testing doesn't give you the final verdict on whether something is an allergy trigger. Your doctor may also consider the history of your child's contact with pollen or food and any reactions he's had. 

    Allergy testing can give faulty results, so the results must always be interpreted carefully and cautiously.
