Why can jw's give blood samples for testing in a medical setting? I was with someone once (non jw related) who was getting multiple tests done and they must have taken a good pint all together in separate vials. How do jw's square this with their blood policies? The blood is not poured out onto the earth but in the end much of it is disposed of (medical waste?).
I know my jw does not object to giving blood samples but will not give to save the life of another.
