Pham et al. stated that their serologic data for anti-D are “in accordance with the incomplete serologic data obtained”1 by one of the undersigned authors.2 Because data, conclusions and recommendations in the 2011 paper1 are in accordance with our study published in 2000, our data2 cannot be labeled “incomplete”. Limitations imposed by the format of this Letter do not allow reference to all additional corroborating data published since 2000, specifically in 20063 and continuously updated online (http://www.uni-ulm.de/∼wflegel/RH/RIR/rirres.html). Pham et al. should cite these references that provide data supporting their conclusions.
