*The RhD antigen density of a sample was calculated as median of the epitopes per cell detected by the 22 IgG monoclonal anti-D.

F3-151

Geometric mean of the RhD antigen densities.

F3-152

Median RhD antigen density as percentage of control cells with comparable Rhesus phenotypes (CcDee 12,532 RhD antigens/cell; ccDEe 19,062).

F3-153

The RhD antigen densities of all three D^VItypes were significantly different from one another (P < .007, t-test with correction for multiple testing (n = 3) according to Bonferroni-Holm).
