1.1 This practice provides a protocol for rapid, in vitro screening for whole complement activating properties of solid materials used in the fabrication of medical devices that will contact blood.

1.2 This practice is intended to evaluate the acute in vitro whole complement activating properties of solid materials intended for use in contact with blood. For this practice, the words serum and complement are used interchangeably (most biological supply houses use these words synonymously in reference to serum used as a source of complement).

1.3 This practice consists of two procedural parts. Procedure A describes exposure of solid materials to a standard lot of human serum, using a 0.1-mL serum/13 x 100-mm disposable test tube. Cellulose acetate powders and fibers are used as examples of test materials. Procedure B describes assaying the exposed serum for significant functional whole complement depletion as compared to control samples.

1.4 This practice does not address function, elaboration, or depletion of individual complement components, nor does it address the use of plasma as a source of complement.

1.5 This practice is one of several developed for the assessment of the biocompatibility of materials. Practice F 748 may provide guidance for the selection of appropriate methods for testing materials for other aspects of biocompatibility.

1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
