Blood bank performs testing to determine the blood type of patients, using the latest technology, gel card method and compatibility testing (to identify compatible blood products for blood transfusions), along with a battery of tests to ensure and enhance quality.
Standards are set for the collection and processing of each blood product. Whole blood is typically separated (via centrifugation) into its components, with red blood cells (RBC) in solution being a commonly used product. Units of WB and RBC are both kept refrigerated at 1-6 C, with maximum permitted storage period (shelf life) of 42 days. First-in-first-out inventory management approach is the standard presently.
Plasma is frozen promptly and is intended for transfusion, it is typically labeled as fresh frozen plasma. Cryoprecipitate can be made from other plasma components. These components are stored at -30C or below.
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 have a shelf life of five days and stored at room temperature 20 – 24 C and in agitation. Since they are stored at room temperature in nutritive solutions, they are at high risk for growing bacteria.
The screening includes testing for diseases that can be transmitted by a blood transfusion, including HIV (HIV 1 & 2 Ab with Ag), viral hepatitis (HBsAg, HBcAb, HCV Ag & Ab), Malaria, Filaria, Syphilis (VDRL). All the testing is carried out by the team of well trained blood bank technologist on fully automated ELISA processors, round the clock. Our blood bank has cleared all the eligibility guidelines as mandated by the Food and Drug Administration Department. The safety and reliability has been the top priority.
