Pak J Med Health Sci Jan ;6(2):362-5.

Objective: To determine the distribution pattern among the students of Avicenna Medical College in relation to ABO blood groups. Study design: Cross sectional study Place and duration of study: Avicenna Medical College Lahore from 1-12-2011 to 29-02-2012. Materials and methods: Finger prints were collected from the subjects after obtaining their informed consent in the month of 1 December, 2011 to 29 February, 2012. A total of 100 MBBS, 3rd year students of the Avicenna Medical College Lahore participated in the study. Finger prints were recorded on a plain white paper with a stamp pad by plain and rolled method and each finger print was assigned by their serial numbers and roll no. of student. The Name and general information of the students like Age, Sex and Blood groups were recorded on the Proforma. All the subjects were in the age range of 19-25 years consisting of 30 male and 70 female students. Ethical clearance was obtained from the institutional Ethical Committee. Results: Out of hundred participants majority were showed the trend and most common pattern belonging to Loop pattern 50%, followed by whorl pattern which was 42%, a very small proportion belonging to Arch pattern which was only 8%. The most common blood group pattern was B +ve 48% which showed commonality and community trend followed by O+ve which were 28%. Participants belonging to A+ve were 15%. Blood groups AB +ve were 6% and B-ve was 2% whereas A-ve was very uncommon 1% only. Maximum no were B+ve whereas least common was A –ve. relationship of different finger printing pattern with different blood groups but when we applied Chi-squared test at P-value ≤ 0.05 with 8 degree of freedom. It came out to be 7.89 which is much less than the cut off value at 0.05 which was 15.51 which revealed that the association was not found to be significant statistically at this level but this finger print pattern might be associated with blood groups , biologically which is still to be proved. Conclusion: Loops are the most commonly occurring finger-print pattern and Arches are the least common. Blood group B positive is the most common and A negative is the rarest. Loops are predominant in blood group A +ve, B +ve and O+ve in individuals. Whorls are more common in blood group B+ve and O+ve and A+ve and least common in A-ve, and B-ve. Loops and Whorls are maximum seen in blood group B+ve while whorls are more common in blood group B+ve and O+ve.
