My name is Roberto Porpino and I work in a blood bank in Recife- Brazil. I'd like very much to find many friends who works about antigens fenotyping, We coud talk about our experiences and perhaps we coud help ourselves. In Recife, I find U negative,first fenotyping s and everybody who is s neg , I fenotype for S. So, I've found some U-, because almost every S- s- is U-. Sorry for my bad English ! I woud like very much to be your friend, because I love fenotyping donners and find the phenotip that the patient needs.
