The term “weak D type” for a distinct D variant is not invalidated if later an anti-D is observed, no matter if it is allo or auto in nature. Introducing anti-D immunization events as defining criteria into the terminology, as proposed by Pham et al.1 and others, is a step backwards. We regularly transfuse many partial D patients, like those carrying DVII, with D positive blood; and no one takes issue. Conversely, there are patients with distinct weak D types who can produce anti-D and must be transfused with D negative blood; we should get used to this approach as well.
