Adhering to strict laboratory protocols is essential for patient safety. If a blood sample tube arrives in the laboratory with an incorrect, illegible, or damaged label, the sample must be rejected outright. Under no circumstances should laboratory staff attempt to relabel, correct, or guess the identity of the sample. The correct procedure is to immediately contact the clinical ward or phlebotomist, explain that the sample is unacceptable due to labeling issues, and request that a new sample be drawn from the patient with proper identification and labeling. Accepting an improperly labeled sample is one of the most common root causes of 'wrong blood in tube' errors, which can lead to fatal transfusion mistakes. This policy is a cornerstone of quality management in transfusion services.
