Can you transfer blood straight from one person to another?

Transferring blood directly from one person to another without any processing is not recommended due to the risk of transmitting infections, blood type incompatibility, and potential adverse reactions. Blood transfusions are typically done through blood donation centers where donated blood is carefully screened, tested, and processed to ensure safety and compatibility with the recipient. It is important to follow proper medical procedures and protocols to minimize risks and ensure the well-being of both the donor and the recipient.
