People with spina bifida are also at increased risk for latex allergy. Any exposed worker who experiences these symptoms should be evaluated by a physician, since further exposure could result in a serious allergic reaction. Taking a complete medical history is the first step in diagnosing latex allergy. Other diagnostic tools include a standardized glove-use test or skin tests that involve scratching or pricking the skin through a drop of liquid containing latex proteins. However, no approved materials are yet available to use in skin testing for latex allergy.
Testing is also available to diagnose allergic contact dermatitis.
In this test a special patch containing latex additives is applied to the skin and checked over several days. Occasionally, tests may fail to confirm a worker who has a true allergy to latex, or tests may suggest latex allergy in a worker with no clinical symptoms. Therefore, tests results must be evaluated by a knowledgeable physician. Once a worker becomes allergic to latex, special precautions are needed to prevent exposures during work as well as during medical or dental care. Many facilities maintain latex-safe areas for affected patients and workers.
