- A blood bank is a cache or bank
of blood or blood components, gathered as a result of blood donation,
stored and preserved for later use in blood transfusions.
- A blood bank is
a place designed especially for the storage of blood and blood products.
A blood bank is a health care facility that draws
blood from voluntary donors, and tests, processes, stores, and distributes
human blood and blood components.
- One unit of
packed red blood cells (RBC) contains approximately 200mL red blood cells,
100 mL optisol AS-5 and ~30mL plasma. RBC must be stored between 1-6
degrees C and have a shelf life of 42 days.
- Process blood within 24 hours of collection; with the exception that
plasma and serum on all patients must be stored within 2 hours of
collection wherever possible.
- Screening for infectious disease agents is a major component of
ensuring blood and plasma safety. This type of screening focuses on
detection of infectious agents that may have eluded detection through
routine donor screening processes.
- Blood and donors are screened for hepatitis, AIDS, malaria and other
infectious diseases. Blood type is determined by
which antibodies and antigens the person's blood produces.
The most common blood type is O.
- The blood bank technology market includes products and services that
enable blood centers to collect, purify, and store blood components. These
products include automatic and manual collection products, filters for
removal of white blood cells from red blood cells, IT applications for
blood centers/blood banks, post-collection component processing, and
sterile solutions in collection bag sets.
- Due to a shortage of donors and strict deferral guidelines, the global
blood market is driven by a constrained supply and episodic shortages of
blood and blood components. There is also a continuing demand for
increased safety in the world’s blood supply as well as a constantly
growing demand for red blood cells and for platelets, plasma, stem cells
and immune ocomponent cells.
The American Red Cross has traditionally been the largest
player in the US for supplying blood to hospitals, the largest end user of
blood units. In the US, the American Red Cross has historically managed
45% of the country’s blood supply.
In developed countries, 100% of the 45 million donations made are
routinely tested for transfusion-transmissible infections such as HIV,
Hepatitis C, Hepatitis B, syphilis, and others.
In developed countries, blood banks routinely take many steps to
ensure the safety of their blood and blood products, including donor
screening and deferral, proper collection and bar-coding of blood
donations, laboratory screening, and proper storage and handling.
- Worldwide more than 70 million units of blood are collected annually,
the majority in the form of whole blood, but also by harvesting specific
blood components. The availability of blood is essential for patients
undergoing surgery, for cancer patients and for hemophiliacs.
