Blood component production. Technician placing vials of drug components in a pasteurisation machine. This laboratory separates blood plasma into its components that are then used in transfusions. These include plasma proteins, growth and coagulation factors, albumin, and immunoglobulin. The components are pasteurised (heated to a high temperature) to remove any possible bacterial contaminants.
