    Withdrawn Rationale:

    This practice provided a protocol for rapid, in vitro screening for alternative pathway complement activating properties of solid materials used in the fabrication of medical devices that contact blood.

    Formerly under the jurisdiction of Committee F04 on Medical and Surgical Materials and Devices, this practice was withdrawn in April 2016. This standard is being withdrawn without replacement because it was decided by experts in the area that better ELISA methods existed for conducting this testing and that the method was no longer needed.

    1. Scope

    1.1 This practice provides a protocol for rapid, in vitro screening for alternative pathway 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 alternative pathway complement activating properties of solid materials intended for use in contact with blood. For this practice, serum is synonymous with complement.

    1.3 This practice consists of two procedural parts. Procedure A describes exposure of solid materials to a standard lot of C4-deficient guinea pig serum [C4(-)GPS], using 0.1-mL serum per 13 × 100-mm disposable glass test tubes. Sepharose CL-4B is used as an example of test materials. Procedure B describes assaying the exposed serum for significant functional alternative pathway complement depletion as compared to control samples. The endpoint in procedure B is lysis of rabbit RBC in buffer containing EGTA and excess Mg++.

    1.4 This practice does not address function, elaboration, or depletion of individual complement components except as optional additional confirmatory information that can be acquired using human serum as the complement source. This practice does not 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 F748 may provide guidance for the selection of appropriate methods for testing materials for other aspects of biocompatibility. Practice F1984 provides guidance for testing solid materials for whole complement activation in human serum, but does not discriminate between the classical or alternative pathway of activation.

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