Across Academy, which we established in 2021, is a candidate to be a scientific resource for national and international blood centers. We organize congress under the name of Across Academy with the participation of technicians, nurses and physicians working at Blood Centers. In addition, in 2021, we brought our book “ABO Grouping and RH Typing”, the first of our “Problems and Solutions in Immunohematology Laboratories” book series, to all employees at Blood Centers. Across Academy will continue to be with you by sharing scientific articles with you online every month.
