Cherie Gregory, left, both allergy and immunization technicians with the 35th Medical Operations Squadron, at Misawa Air Base, Japan, Jan. 14, 2016. Skin tests are performed on a patient’s back or forearm with a drop of a suspected allergen pricked or scratched on the surface of the skin. Many suspected allergens are tested at the same time. If the patient is allergic to one of the tests, a redness and swelling will appear at the test spot. Mendoza is from Pocatello, Idaho, and Gregory is a Tampa Bay, Florida, native.
