The economic side of blood banking and plasma fractionation

While cellular components have a relatively short half-life, must be necessarily administered group-specifically and kept available on a round-the-clock basis, all of which add significantly to the basic cost per unit, products isolated from plasma are not handicapped by these disadvantages. Another important advantage for the production of plasma components lies in the fact that the raw material may be also collected through plasmapheresis, a process which allows the collection of significantly greater amounts of plasma from one donor as compared to conventional whole blood collection. Quite understandably, the maintenance of whole blood and cellular component supplies has been left to national and/or non-profit organizations, while commercial firms run a profitable business with the production and distribution of plasma fractions. The method for the selective isolation of plasma fractions developed in our blood transfusion service solves the high cost problems involved in conventional fractionation methods but does not solve the ethical and economical problem related to discarding precious unused raw material.
