Blood Banking

What is the second most important test to complete in blood banking?

• Crossmatching

• Antibody screen

According to AABB, what is the risk of transfusing an incompatible unit compared to the risk of depriving the patient of oxygen-carrying capacity?

• The risk of transfusing an incompatible unit is greater

• The risk of depriving the patient of oxygen-carrying capacity is greater

• Both risks are equal

• There is no risk involved

• The antibody is transferred from the recipient to the donor during transfusion

What is autologous blood?
