Blood Bank
Chandan is having Blood bank at Indra Nagar branch, Lucknow. It is a center where blood gathered as a result of blood donation is stored and preserved for later use in blood transfusion.
Whole blood or blood with RBC, is transfused to patients with anaemia/iron deficiency. It also helps to improve the oxygen saturation in blood. It can be stored at 1.0 °C-6.0 °C for 35–45 days.
Platelet transfusion, is transfused to those who suffer from low platelet count. This can be stored at room temperature for 5–7 days. Plasma transfusion is indicated to patients with liver failure, severe infections or serious burns. Fresh frozen plasma can be stored at a very low temperature of -25 °C for up to 12 months.
Collection and processing
Certain standards are set for the collection and processing of each blood product. "Whole blood" (WB) is the proper name for one defined product, specifically unseparated venous blood with an approved preservative added. Most blood for transfusion is collected as whole blood. Autologous donations are sometimes transfused without further modification, however whole blood is typically separated (via centrifugation) into its components, with red blood cells (RBC) in solution being the most commonly used product. Units of WB and RBC are both kept refrigerated at 33.8 to 42.8 °F (1.0 to 6.0 °C), with maximum permitted storage periods (shelf lives) of 35 and 42 days respectively. RBC units can also be frozen when buffered with glycerol, but this is an expensive and time-consuming process, and is rarely done. Frozen red cells are given an expiration date of up to ten years and are stored at −85 °F (−65 °C).
The less-dense blood plasma is made into a variety of frozen components, and is labeled differently based on when it was frozen and what the intended use of the product is. If the plasma is frozen promptly and is intended for transfusion, it is typically labeled as fresh frozen plasma. If it is intended to be made into other products, it is typically labeled as recovered plasma or plasma for fractionation. Cryoprecipitate can be made from other plasma components. These components must be stored at 0 °F (−18 °C) or colder, but are typically stored at −22 °F (−30 °C). The layer between the red cells and the plasma is referred to as the buffy coat and is sometimes removed to make platelets for transfusion. Platelets are typically pooled before transfusion and have a shelf life of 5 to 7 days, or 3 days once the facility that collected them has completed their tests. Platelets are stored at room temperature (72 °F or 22 °C) and must be rocked/agitated. Since they are stored at room temperature in nutritive solutions.
Storage and management
Routine blood storage is 42 days or 6 weeks for stored packed red blood cells, by far the most commonly transfused blood product, and involves refrigeration but usually not freezing.Transfusions of platelets are comparatively far less numerous, but they present unique storage/management issues. Platelets may only be stored for 7 days, due largely to their greater potential for contamination, which is in turn due largely to a higher storage temperature.
