The nurse will clean your child's skin with alcohol and draw numbers on it. The numbers match up with the specific allergen that is being tested. A drop of liquid containing the allergen is then placed on the skin. We also use a drop of saline and a drop of histamine. These are used to make sure your child's skin is reacting normally. A lancet (small, thin needle) is then used to slightly puncture the skin's surface. This allows the allergen to enter the skin. A child may experience mild discomfort but the procedure is not painful. Your child's arm will have to be held still for this part of the procedure. After the skin is pricked, we allow 15 minutes to see if the skin has reacted.
