ECL Central Hospital Kalla Blood Bank is a government-operated blood bank located in Kalla, Asansol, Paschim Bardhaman district, West Bengal, India. It operates under the Eastern Coalfields Limited (ECL) Central Hospital and serves as a key emergency blood supply center for the industrial and residential population of Asansol and nearby areas. The facility runs 24 hours a day and focuses on providing whole blood rather than separated components. The blood bank primarily supports patients from the hospital and surrounding communities by providing essential transfusion services. It operates on a 24×7 basis, allowing round-the-clock access for medical emergencies. However, it does not offer apheresis or individual blood component separation facilities, which limits advanced transfusion options.
