What should be done when a laboratory test tube is received with double labeling?

When a laboratory test tube is received with double labeling, it is essential to prioritize patient safety. Double labeling can create confusion regarding the identity of the specimen, increasing the risk of errors in processing and reporting results. This could lead to serious consequences, such as a patient receiving the wrong diagnosis or treatment based on incorrect information.

Rejection of the specimen is a standard practice in such situations to ensure the integrity of the testing process and to protect patient safety. It allows for verification and resolution of any discrepancies before further steps are taken. This fosters a quality assurance environment where only accurately identified specimens proceed, minimizing the risk of medical errors.

In other scenarios, processing the specimen normally could compromise safety, as the ambiguity surrounding the labeling might lead to misinterpretations. Flagging the specimen for review may still pose risks, as it doesn't eliminate the fundamental issues arising from the double labels, and testing it only upon patient confirmation could delay critical care or lead to further complications in treatment. Therefore, rejecting the specimen is the most prudent and responsible action to take in this situation.
