Equipment could be contaminated if inappropriate cleaning, disinfection or sterilisation procedures are done.
Various techniques are being used or in improvement to cut back infectivity of blood products, including solvent-detergent processing of plasma and nucleic acid cross-linking by way of photochemical reactions with methylene blue, riboflavin, psoralen and alkylating brokers. Many options exist to further strengthen blood basic safety through developments in infectious ailment screening and pathogen inactivation solutions [21, 22].
