This study was undertaken to find out the trend of blood group distribution (ABO and Rh) among the 1310 Nepalese attended in Tribhuvan University Teaching Hospital and Nepal Medical College Teaching Hospital Kathmandu. The frequency of distribution of A, B, AB and O was 28.5%, 27.3%, 8.7% and 35.5% respectively. Only 0.8% of them were found to be Rh (-) ve. In this population of study, O (+) ve blood group was found to be predominant among the Brahmins, Magars and Gurungs. A (+) ve blood group was predominant among the Chhetris, and B (+) ve among the Sherpas and the Lamas.
