Alsever's solution is a saline liquid used to prevent coagulation of blood. [ 1 ] [ 2 ] It is composed of 2.05% dextrose , 0.8% sodium citrate , 0.055% citric acid , and 0.42% sodium chloride . For usage, an equal volume of blood is gently, but thoroughly, mixed with the solution.
Blood plasma is the liquid component of blood, which contains dissolved proteins, nutrients, ions, and other soluble components. In whole blood, red blood cells, white blood cells, and platelets are suspended within the plasma. The goal of plasma purification and processing is to extract specific materials that are present in blood, and use ...

Blood fractionation is the process of fractionating whole blood, or separating it into its component parts. This is typically done by centrifuging the blood. The resulting components are: a clear solution of blood plasma in the upper phase (which can be separated into its own fractions, see Blood plasma fractionation), the buffy coat, which is ...

A blood product is any therapeutic substance prepared from human blood. [1] This includes whole blood ; blood components; and plasma derivatives. Blood components include: red blood cell concentrates or suspensions; platelets produced from whole blood or via apheresis; Granulocyte , plasma ; and cryoprecipitate .
As a result, blood can now be stored for much longer, up to 21 days. [4] ACD was developed into CPD (citrate-phosphate-dextrose) in 1957, [5] a version with phosphate added intended to reduce phosphate leakage from red blood cells. It does not improve shelf life appreciably, but patient recovery is improved.
Blood taken from a healthy donor can be separated into its component parts during blood donation, where the needed component is collected and the unharvested components are returned to the donor. Fluid replacement is usually not needed in this type of collection. In many countries, apheresis donors can donate platelets more often than those ...
