For example, during certain surgical procedures, some blood may be diverted from the body in a process called hemodilution. The blood remaining in the patient is diluted. Later, his blood in the external circuit is directed back into him, thus bringing his blood count closer to normal.

The details may vary, and new procedures, treatments, and tests will certainly be developed. It is not our place to analyze each variation and render a decision. A Christian must decide for himself how his own blood will be handled in the course of a surgical procedure, medical test, or current therapy. Ahead of time, he should obtain from the doctor or technician the facts about what might be done with his blood during the procedure. Then he must decide according to what his conscience permits.
