A blood bank is a specialized service that:

·       Collects blood from eligible donors at the center, in hospitals, and through mobile camps.

·       Tests every unit for blood group (ABO and Rh) and for major infections like hepatitis B, hepatitis C, HIV, syphilis and, in many centers, malaria and other region‑specific diseases.

·       Processes whole‑blood donations into components such as red blood cells, platelets and plasma so that each part can be used for different patients.

·       Stores these components under strict temperature and time‑limit controls.

·       Supplies compatible units to hospitals and wards when doctors request them for patients.

Licensed blood banks follow national and provincial standards so that both donors and recipients are protected at every step.
