Whole blood is collected from a donor and used for transfusions or further processed into its individual components, such as red blood cells, platelets, and plasma.
The collection, processing, and storage of whole blood are crucial for ensuring its safety and effectiveness.
Collection of Whole Human Blood
Whole blood is collected using a sterile collection bag, needle, and tubing with anticoagulants to prevent clotting.
Before donation, the donor's health history and vital signs are evaluated for eligibility.
Once collected, the blood is transported to a blood bank or processing facility for further processing.
Processing of Whole Human Blood
Blood is separated into its components using a centrifuge, which spins the blood at high speed to separate:
Red Blood Cells (RBCs)
Platelets
Plasma
These components are further processed into blood products such as packed red blood cells, platelet concentrates, and fresh frozen plasma.
Storage of Whole Human Blood
Blood must be stored at 1-6°C to maintain its viability and prevent bacterial growth.
Specialized refrigerators with temperature monitoring and alarms ensure proper storage conditions.
Whole blood has a shelf life of up to 42 days, after which it is discarded.
Safety Testing and Transfusion
Donated blood undergoes rigorous testing to screen for infectious diseases such as HIV, Hepatitis B and C, and syphilis.
Blood type compatibility is checked before transfusion to ensure patient safety.
