THERAFLEX UV-Platelets system

The THERAFLEX UV-Platelets system is not available on the market

The THERAFLEX UV-Platelets system is intended to inactivate a broad spectrum of pathogens as well as residual donor leucocytes in platelet concentrates (apheresis or Buffy-coat) suspended in Platelet Additive Solution (PAS) in order to reduce the risk of transfusion-transmitted infection and leucocyte-associated adverse reactions

Exposure to UV light causes DNA damage, inactivating bacteria, viruses, parasites and leukocytes.
