PREVALENCE OF ABO BLOOD GROUPING AND RH TYPING AMONG UNDERGRADUATE ALLIED HEALTH SCIENCE STUDENTS AT MEENAKSHI ACADEMY OF HIGHER EDUCATION AND RESEARCH

Abstract

The present study analyzed the distribution of ABO and Rhesus (Rh) blood groups among 100 undergraduate students of the Faculty of Allied Health Sciences, MAHER. Demographic data, including gender and age, were collected and examined. The study population consisted of 65% females and 35% males, with the majority (52%) belonging to the 21-year age group. Analysis of ABO blood group distribution revealed that O Positive was the most common blood group among females, followed by B Positive and A Positive. Among males, B Positive (37%) was most prevalent, followed by O Positive (28%) and A Positive (25.7%). Rare blood groups such as AB Negative, A Negative, and O Negative were observed at very low frequencies.Rh typing showed a clear predominance of Rh-positive individuals (93%) across the study population, with 94% of males and 93% of females testing Rh positive. Only 7% of the overall participants were Rh negative.In conclusion, O Positive emerged as the most frequent blood group, whereas AB Negative was the least common. The predominance of Rh positivity across both genders aligns with previously reported regional trends in South India. These findings contribute to the existing knowledge on blood group prevalence, with implications for transfusion safety, donor awareness, and population genetics.
