A blood bank is a facility that collects, tests, processes, and stores blood and blood products for transfusions. If a blood bank is under pipeline, it means that it is in the process of being established or developed.

This could include activities such as:

1. Planning and designing the facility, including the location, size, and layout.

2. Obtaining necessary permits and approvals from government agencies and regulatory bodies.

3. Procuring equipment and supplies required for blood collection, processing, and storage.

4. Recruiting and training staff, including blood bank technicians, phlebotomists, and administrative personnel.

5. Establishing relationships with local hospitals and clinics to ensure a steady supply of blood and blood products.

6. Developing and implementing protocols and procedures to ensure the safety and quality of the blood and blood products.

7. Conducting public awareness campaigns to encourage blood donation.

The establishment of a blood bank is a critical component of healthcare infrastructure and provides a vital source of blood and blood products for medical treatments and surgeries.
