Biological Reactivity Tests, In Vivo

Biological Reactivity Tests, In Vivo are designed to determine the biological response of animals to elastomerics, plastics and other polymeric material with direct or indirect patient contact, or by the injection of specific extracts prepared from the material under test. Three tests are described: 1. Systemic Injection Test - Designed to determine the systemic biological responses of animals to plastics and other polymers by the single-dose injection of specific extracts prepared from a sample. 2. Intracutaneous Test - Designed to determine the local biological responses of animals to plastics and other polymers by the single-dose injection of specific extracts prepared from a sample. 3. Implantation Test - Designed to evaluate the reaction of living tissue to the plastic and other polymers by the implantation of the sample (specimen under test) itself into animal tissue. With the exception of the Implantation Test, the procedures are based on the use of extracts that, depending on the heat resistance of the material, are prepared at one of the three standard temperatures: 50°, 70°, and 121°. Therefore, the class designation of a plastic must be accompanied by an indication of the temperature of extraction e.g., IV - 121°, which represents a class IV plastic extracted at 121°).
