Complement Activation

Complement Activation

The Complement Activation test is used to determine the potential for activation of the complement system by a medical device. This humoral immune response, caused by the introduction of a foreign material into the body, can lead to adverse effects such as tissue damage.

This test was designed to fulfill the immunology testing requirement found in the AAMI/ANSI/ISO 10993-4 guidelines for selection of tests for interactions with blood. Nelson Laboratories includes three time points in the assay to look at possible levels of activation over time.

Study Outline

The Complement Activation test is performed in vitro using commercially prepared Enzyme Immunoassay (EIA) kits that detect the presence of specific complement proteins:
  • C3a: An enzyme generated during the activation of the complements system via the classical or the alternate pathway
  • SC5b-9-complex: The soluble, non-lytic form of Terminal Complement Complex (TCC) generated as a consequence of activation of the complement system
