Question

The blood groups of both the diner and recipient must be known before transfusing blood​

Answer 1

Answer:

yes

Explanation:

This is because some units of donor blood may not fully match the recipient's, even though they have the same ABO and Rh types. Before a person can get a transfusion of red blood cells, another lab test called a cross-match must be done to make sure that the donor blood is compatible with the recipient's.
