OB08

Thanks for the help!

Hi. I am new to this. I am an OB gyn physician, and I have a question about Rhogam. I donated countless units of blood in different cities along the way and always got cards saying I was O pos. Then after a recent miscarriage my hospital typed me as O neg. I was shocked being ignorant to how complicated Rh can get. Does this mean I am likely to be weak D or partial D? I got rhogam because it seemed to be the safest thing to do. Any thoughts? Thanks
