1.1 This practice covers the introduction of foreign materials into the body that may have an impact on the immune system. One possible effect is that the immune system will be depressed or certain cell types may be affected. Immunotoxicity may be determined with blood and tissue samples from the animals used in the other biocompatibility test procedures such as implantation and blood contact test protocols. It is also possible to use these techniques with blood samples from human patients in a clinical trial. Any procedures with human subjects should follow the appropriate rules of the local institutional review board and the appropriate regulatory agencies. This document may serve as an annex to Practice F748.

1.2 The material may affect the humoral immune response, the cell mediated response, or both.
