Hi Guys,
Has anyone seen the following scenario before and , if so, how common is it?
2002 male O neg patient transfused 4 units of Oneg and 6 O pos.
2012 and 2014 antibody screen negative. Now using the same methodology (DiaMed IAT), we have a strong anti-D. No D positive units transfused since 2002.
Why is anti-D now apparent 20 years after the transfusion of D pos cells but not 10 years ago?
Cheers,
