Diagnosis: Whole blood collection:Low-volume unit
• The AABB standards state that for blood collection, the volume of the collected blood should be proportional to the amount of anticoagulant/preservative solution that is in the collection container.
• In the United States, the volume of blood collected during routine phlebotomy is either 450mL ± 10% (405 to 495 mL) or 500 mL ±10% (450 to 550 mL).
• If 300 to 404 mL of whole blood is collected into an anticoagulant volume intended for 450 ± 10%, or if 333 to 449 mL of whole blood is collected into an anticoagulant volume intended for 500 mL ± 10%, RBCs prepared from the unit should be labeled “Red Blood Cells Low Volume.”
• No other components should be made from this low-volume collection.
• If the collection volume is less than 300 mL, the amount of anticoagulant must be proportionally decreased.
