I'm kinda thinkin that all of the fraction crap the bORG has put into the rules is getting many of the R&F confused.
Especially if they are under duress as this young woman was. The fact that the hospital got direct instructions from the woman telling them she would only take platelets and plasma raises a flag. She probably thought those two componants were considered to be fractions.
I also believe the hospital was correct in taking the stand it did
