Blood Transfusion

The hospital blood transfusion service is responsible for ensuring that blood components for transfusion to patients are compatible. The biomedical scientists who staff the laboratory carry out blood group, antibody screening and antibody identification (if required) including the routine testing on antenatal patients.

Two Sample Rule

To ensure patient safety, the transfusion laboratory requires the patient to have been tested on more than one occasion prior to issuing red blood cells.  The two separate samples for Group and Save must have been taken at different times, i.e at different phlebotomy sessions. It is not acceptable to collect two blood samples at the same time and label them a few minutes apart. Such specimens will be rejected.
