I'd like a little clarification from those technologists that indicate their facilities have a policy to give O+ blood to males, and de facto to females past child bearing age, in an emergent trauma and O= blood to females (of child bearing age). While I understand that when O= is not readily available it may be necessary, at times, to do this, but to basically say if you're a male of Rh negative status we will give you Rh positive blood and we guarantee to give you a circulating antibody to D antigen for all your future years and increase your medical costs for all of those future antibody IDs that technologists will have to deal with or send out for reference. If that is your 'policy' then I have a good lawyer I'd like you to talk to. Please explain.
