1. Packed red blood cells

   Packed red blood cells, also known as packed cells, are red blood cells that have been separated for blood transfusion. The packed cells are typically used in anemia that is either causing symptoms or when the hemoglobin is less than usually 70–80 g/L (7–8 g/dL). In adults, one unit brings up hemoglobin levels by about 10 g/L (1 g/dL). Repeated transfusions may be required in people receiving cancer chemotherapy or who have hemoglobin disorders. Cross-matching is typically required before the blood is given. It is given by injection into a vein.Side effects include allergic reactions such as anaphylaxis, red blood cell breakdown, infection, volume overload, and lung injury. With current preparation methods, the risk of viral infections such as hepatitis C and HIV/AIDS are less than one in a million. Packed red blood cells are produced from whole blood or by apheresis. They typically last for three to six weeks.The widespread use of packed red blood cells began in the 1960s. It is on the World Health Organization's List of Essential Medicines. A number of other versions also exist including whole blood, leukocyte reduced red blood cells, and washed red blood cells.

1. Packed red blood cells

   In transfusion medicine, packed red blood cells are red blood cells that have been collected, processed, and stored in bags as blood product units available for blood transfusion purposes. The collection may be from a "whole blood" donation followed by component separation, or by RBC apheresis. The processing and the storage can occur at a collection center and/or a blood bank. RBCs are mixed with an anticoagulant and storage solution which provides nutrients and aims to preserve viability and functionality of the cells, which are stored at refrigerated temperatures for up to 42 days, except for the rather unusual long-term storage in which case they can be frozen for up to 10 years. The cells are separated from the fluid portion of the blood after it is collected from a donor, or during the collection process in the case of apheresis. The product is then sometimes modified after collection to meet specific patient requirements.
