In order to achieve the slogan of Towards a Sustainable University, the Department of Anesthesia Techniques and to achieve the third goal of the Sustainable Development Goals (Good Health and Well-Being), the Department of Anesthesia Techniques held a scientific workshop on (Blood group testing), where the course included examining blood groups and also defining each group.<br />Each group differs from the other group due to the presence of certain substances in the blood cells and serum. If two groups that are not completely compatible mix, agglutination occurs that may have serious consequences.<br />To avoid this, when transfusing blood, it must be taken into account that the donor's blood is completely compatible with the recipient's blood.<br />The donor's blood can be from group (O) as it does not contain antibodies, and is known as the universal donor<br />The RH factor must be taken into consideration, and there are two types: negative RH -ve and positive RH +ve.
