Detection of complement (c3d) coated cells in a newborn due to maternal anti-i

D R Branch


A case of a positive direct antiglobulin test on a newborn's cord red blood cells caused by maternal anti-i is reported. The direct antiglobulin test was moderately positive using polyspecific antiglobulin reagent and monospecific anti-C3d, but negative using monospecific anti-IgG. The infant showed no clinical signs of hemolytic disease of the newborn.
