PCV is the percentage of red blood cells in circulating blood. A decreased PCV generally means red blood cell loss from any variety of reasons like cell destruction, blood loss, and failure of bone marrow production. An increased PCV generally means dehydration or an abnormal increase in red blood cell production.
BACKGROUND: A photochemical treatment (PCT) process has been developed to inactivate pathogens and white blood cells (WBCs) in therapeutic plasma. Process validation studies were performed in three European blood centers under routine operating conditions. STUDY DESIGN AND METHODS: Each center prepared 30 apheresis and 30 to 36 whole bloodâderived plasma units for PCT. Each whole bloodâderived plasma unit contained a mixture of two to three matched donations.
