Labeling Requirements for Blood and Components
• (?) symbology
• (?) of product
• (?) of preparation (whole blood, apheresis)
• Storage (?)
• Preservatives/(?)
• (?) in pooled components
• (?) of collection & processing facility
• (?) (& time if applicable). When expiration time not indicated, expiration is at midnight.
• Identification number for unit or pool
• Donor category (volunteer, autologous)
• (?), if applicable.
• (?)information
• (?) regarding recipient identification, Circular of Information, infectious disease risk, & prescription requirement
• (?): “For Autologous Use Only.”
Biohazard label if any infectious disease markers are pos or “Donor Untested” if testing not performed.
