* When a child’s blood volume is adequate to tolerate collection of a 7 mL sample, it is best to collect the full 7 mL sample to avoid re-draws if an antibody is identified or more blood is needed.

** When orders are placed for an Outpatient Transfusion or Preadmission Order, for patients > 5 years old it is preferable to send two full 7 mL samples to avoid re-draw if the patient has antibody that must be identified.

Transporting Samples

All samples must be sent to the Blood Center in a sealed, leak-proof container marked with a biohazard sticker to comply with OSHA safety standards.
