Units of fresh plasma from a single donor are kept frozen in quarantine until at least 2 months after donation. After this period, the donor donates again and thus undergoes a new analysis. If the second analysis produces another negative result, the plasma from the first donation is released for transfusion purposes. This method minimises the risk of using a unit of plasma that may have been obtained during an incubation period of any of the viruses under analysis.
