Question

What can be achieved/can be prevented?

Proper checking of blood before blood donation.

Answer 1

Proper checking of blood before blood donation is required to check that the blood to be transferred is safe in all respects. There are chances of transfer of infectious diseases from the donor if he/she is suffering from any such diseases. Another important factor for checking blood before the donation is to check that the donor is not anemic (does not have anemia).
