Often, yes, but it depends on hospital policy:

·       Some hospitals rely primarily on their own in‑house blood bank and prefer to use that supply for safety and traceability.

·       In emergencies or when special products are needed, they may accept blood from outside licensed banks that meet standards.

If you wish to use a specific blood bank (for example, one run by a trusted NGO or near your home):

·       Talk to the treating doctor or hospital blood bank staff.

·       Ask whether they can accept blood units from that external blood bank for your patient.

·       Follow the hospital’s procedure for receiving and documenting outside units.

The main priority is safety and compatibility; convenience and preference come second.
