With this test, the doctor or nurse will put a tiny bit of an allergen (like pollen or food)&nbsp;on the skin, then <span>prick the outer layer of skin or </span>make a small scratch on the skin. If the area swells up and becomes red (like a mosquito bite), the test is said to be positive, meaning that the child is allergic to that substance. Skin testing allows the doctor to see within about 15 minutes if a child is allergic to the substances tested.</li> <li>A <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/test-immunoglobulin-e.html/">blood test</a> may be used if a skin test can't be done.
