Many approaches are getting used or in progress to lower infectivity of blood products, such as solvent-detergent processing of plasma and nucleic acid cross-linking through photochemical reactions with methylene blue, riboflavin, psoralen and alkylating brokers. Several possibilities exist to even further improve blood protection via developments in infectious condition screening and pathogen inactivation techniques [21, 22].
An environmental monitoring plan in order to monitor the microbiological levels of categorized rooms.
