RO: I don't get where you are coming up with it is the six sigma of prescribing and that six sigma means it is the safest.
Of course you don't. You haven't done your research.
I have posted the source for my comment on other threads on here and it would take some time to find it.
My comments are derived from an FDA document where exactly what I said was stated by, I believe, the person responsible for blood transfusion safety for the US.
I based my comment on what he said - he was the one who made that claim in an FDA document discussing the safety of artificial blood. I am pretty sure it is the same document where the US Army (or was it the Navy?) was trying to convince the FDA that the Jehovah's Witnesses were the ideal population on which to continue testing artificial blood products.
I will look for that document if you are really interested in reading it. If not...please don't waste my time.
Which brings up this question - did you bother to read the link I posted in my last comment?
