When to Get an Allergy Test for Your Child
Does your child get a runny nose during pollen season or hives after eating certain foods? It could be time for allergy testing.
Your doctor might first try allergy medication for your child. If it doesn't work, your doctor may send your child to an allergist if he has any of these symptoms:
- Cold-like symptoms that last more than a week and happen at the same time each year
- Hives or skin rashes
- Coughing or wheezing, especially at night
The allergist, who specializes in diagnosing and treating allergies, will:
- Ask about your child's symptoms and when he has them.
- Do a physical exam, looking for signs of allergies.
- Ask about your family history. If both parents have allergies, a child has a 75% chance of having allergies. If one parent has allergies, a child has a 50% chance of having them.
If the doctor believes that your child has allergies, testing may be able to confirm what kind she has. They may be skin tests or blood tests. Your child may react to a skin test in just a few minutes. Blood tests take a few days.
If the allergist thinks your child has a food allergy, he may also suggest an elimination diet. Here, your child stops eating certain foods -- like milk, eggs, and peanuts -- to see if they were causing a reaction.
The allergist uses the results of these tests to develop a treatment plan for your child.
