Abstract
- Mixed field agglutination is an important, but rare phenomenon of ABO blood grouping. Contrary to adults, neonatal red blood cells are immature and they present a weak ABO expression, and sometimes this result in a mixed field agglutination pattern. We report here on a case of a neonate who presented with mixed field agglutination on the ABO blood grouping during serologic testing and the neonate had a normal ABO genotype.
