In order to evaluate the correct understanding about one's own blood group and to estimate the discrepancy rate between actual and believed groups, the authors based on the data collected from a questionnaire and the result of ABO blood grouping
through
the processing of 1,723 donor bloods at Red Cross National Blood Center, located in Seoul, between march and May, 1992.
the results were as follows;
1. Donors who did not know one's own ABO and Rh blood group were 1.2% and 55.1% of the total of study, respectively.
2. ABO discrepancy rate in 1,703 blood donors was approximately 3.6%.
3. ABO discrepancy rates in the group aged 17-19, 20-29, 30-39, 40-49 and 50-64 year-old were 2.9%, 3.1%, 5.9%, 8.6% and 2.8%, respectively.
4. ABO discrepancy rates according to the remembrance of donor's blood group were 3.7% in group A, 2.2% in group B, 4.5% in group 0 and 4.8% in group AB.
5. With the actual ABO blood grouping on blood donation, 43(69.3%) out of 62 persons who showed the discrepancy between actual and believed ABO group were found.
