Blood banks test every donated unit of blood for HIV primarily to

- B. increase the storage life of the blood
- C. raise the red cell count of the unit
- D. detect anaemia in the donor
Explanation
One unit of infected blood can transmit HIV directly into the recipient's circulation, so screening donated blood is one of the most effective barriers to spread. The tests used have nothing to do with storage or cell counts.
