We have a new to us, 36 year old Female OB that has a history from the Dr office of being A Neg. We did her Rh by gel and got Pos...repeated on new draw by different Tech, also got Pos. Then did by tube thru Du and got Neg. Any thoughts or suggestions as how to proceed? We are checking on more history and I'm calling the consultative services at the blood center...don't find anything in the Ortho literature I have. Thanks, Kay
