Abstract Introduction Blood systems continue to be ofgreat importance in multiple disciplines such as transfusion medicine, population genetics, forensic medicine and organ transplantation, which are based on the determination of ABO and Rh blood groups. The following work analyzes the erythrocyte phenotyping in a group of students of Biochemistry and Pharmacy of5th, 6th and 7th semesters, UNIFRANZ, El Alto. Material and methods A descriptive case series study was carried out, determining the ABO and RhD systems for direct and indirect tests in order to avoid discrepancies; using the microplate technique as support, according to quality controls in Immunohematology⁹. Results The results showed that 86% were women, the dominant age group was between 18 and 25 years of age. The ABO system determined the highest percentage of group "O" with 93%, highlighting that the AB group was not found in the study group. The RhD system was 100% positive, with no RhD negative phenotypes, neither variant norpartial. Conclusion The phenotyping of blood groups, both direct and indirect, through the microplate platform helps to avoid errors and discrepancies, as recommended by the Manual of Immunohematology in blood services in Bolivia
