How are facilities complying with the accreditation requirement to have a mechanism to ensure that fetal transfusion and fetal blood type ,when performed, is differentiated from that of the mother for intrauterine transfusions? 

I have the same question, does anyone have any input on this?

My first though is the blood group, but so far we have only ever done 1 and both mother and fetus had the same blood group. Would the alkaline denaturation be an acceptable method?
