Blood Bank-Specimens

Blood Bank Specimen Collection Guidelines

Proper patient and specimen identification are of critical importance for safe transfusion. Clerical error is the most common cause of disaster in blood transfusion. A freshly drawn specimen will be required before transfusion of type-specific products when there is any question concerning proper identification of a specimen or patient. Mislabeled, incompletely labeled and unlabeled specimens will not be processed for transfusion. No exceptions to these rules are allowed.

It is strongly suggested that you print and use this list when collecting blood bank samples.

Second ABORH (Blood Type)

National Patient Safety Goals require enhanced methods to verify correct patient identification before blood transfusion. To improve patient safety, Legacy has initiated a process involving the collection of a second specimen (perform a second ABORH) on transfusion candidates with no Legacy Blood Bank history on file. This second sample must be collected at a different time than the first sample. Additional details are available from the Blood Banks.
