palmtree67:- "Do you really think that when God told Noah, "Abstain from blood" he expected Noah to undertand all these modern advances in blood research???"
I think your referring to Acts and not genesis, God never told Noah to "Abstain from blood", in the beginning of chapter 9 Genesis HE said about the killing and eating of flesh with its soul - its blood - you shall not eat(NWT).
kjv -But flesh with the life thereof, which is the blood thereof, shall ye not eat.
niv- But you must not eat meat that has its lifeblood still in it.
