Digital dermatoglyphis in ABO, Rh blood groups.

ABSTRACT

Dermatoglyphics, the study of fingerprints are constant and individualistic. The ridge pattern depends upon cornified layer of epidermis as well as dermal papillae. This study was conducted to correlate between digital dermatoglyphics patterns in ABO, Rh blood groups and evaluates their significance. A total of 200 first year MBBS students with known blood groups from 2004 and 2005 batch of IGGMC, Nagpur were included in the study. Fingerprints were obtained by printing method. Parameters studied were arches, whorls, loops. It was concluded that, whorls were highest in B blood group and the difference was significant with O blood group. Loops were highest in O blood group and were significant with A, B, AB blood groups. Arches were highest in AB blood group and were statistically significant with B and O blood groups. Arches were higher in Rh negative blood group differing statistically with Rh positive blood group.
