The Relation Between Left Thumb Fingerprint Types with Blood Groups and Gender Among Students of Al-Kindy College of Medicine, 2019

Abstract

Background: The skin of the palms and soles is marked by a unique carved ridge which is called dermatoglyphic. Fingerprints are expected to perform some important physiological functions. Fingerprints are classified into a loop, whorl and arch. There are two systems for blood group classification known as: ABO and Rh.
Objectives: To study the pattern of fingerprint on the thumb of the left hand and the association between fingerprint, blood group and gender.
Methods: This study is a cross-sectional study. It was conducted in the department of physiology at Al-Kindy College of Medicine, Baghdad, Iraq from December 2018 to March 2019. Total of 315 persons were selected randomly for this study. After taking consent from the subjects, participants were asked to press their left thumb fingertip on the ink pad and then to Pre-designed form to transfer the fingerprint impression.
Results: Majority of the subjects (38.7%) in the study were of blood group O followed by blood group B, A and AB of whom Rh-positive was dominant. The distribution of fingerprint pattern is higher (59.4%) in loops followed by whorls and arches. Almost the same order was noticed in both ABO blood groups and Rh blood groups, except blood group AB negative were loop and whorl had the same percentage (50.0%).
Conclusions: The study has revealed a significant association between blood group types and gender. This study failed to find significant association neither between fingerprint patterns and gender nor between fingerprint patterns and blood group types.
