    Abstract

    This paternity study was performed with trios in which the putative father was not the biological father (NBF), in order to evaluate the effectiveness of HLA-A and -B phenotyping for routine testing.

    All 372 generated trios had ABO, Rh, MNS, Kell, Duffy, Kidd and HLA (A and B) systems tested.

    HLA-A and -B phenotyping directly excluded 81.73% of NBF. Red blood cell markers excluded 8.82% of NBF missed by HLA; only 0.81% of NBF were not identified by the markers used.

    Each laboratory engaged in disputed paternity testing should evaluate its actual performance in detecting non-biological fathers and its exclusion rates in real trios. These data together can be used as a guide of mother's reliability.
