INTERCEPT Blood System for Platelets



Parasites

The INTERCEPT Blood System for platelets has been shown to inactivate contaminating parasites in platelet products. Various in vitro studies have demonstrated inhibition of parasite replication following photochemical treatment. The results of these studies are summarized in Table 3.
