Many parents assume that a blood or skin test can give a complete answer about their child’s food allergies. In reality, test results are only one piece of the puzzle and must be interpreted carefully.”
Food allergy testing can be very helpful, but it is not perfect. A positive test does not always mean that a child will have a reaction when they eat that food, and a negative test does not guarantee that there is no allergy at all. The most accurate diagnosis usually comes from combining a detailed medical history, a physical examination, and sometimes a supervised food challenge.
If families remove too many foods from a child’s diet based only on test results, it can affect growth and nutrition. Parents should always review allergy test results with their pediatrician or allergy specialist before making major changes. Patient advocates can also support families by helping them prepare questions for the doctor and by making sure they fully understand the plan for follow-up and safety.
