title: Du confirmation.
abstract: The need for repeat antiglobulin testing to detect the Du phenotype in donor blood already labeled as Rh-negative was challenged. The confirmatory testing by hospital transfusion services rejected only 47 units in 2.6 million tested. The confirmatory antiglobulin test for Du currently required of hospital transfusion services could be omitted.
