About this study

  • To evaluate whether residual chemical additives at a level that may induce Type IV allergy in the unsensitized general user population are present in a finished Polychloroprene Rubber Containing Medical Device, Powder Free Polychloroprene Surgical Gloves, Sterile. (CR-SG-140-AF-WH)
  • To meet requirements for claim: This product demonstrated reduced potential for sensitizing users to chemical additives as described in Guidance for Industry and FDA Staff- Medical Glove Guidance Manual. Supporting Test Data: A negative skin sensitization test (Modified Draize-95 Test) on a minimum of 200 non-sensitized human subjects.
