Specimen labels are used to identify and track specimens that will be forwarded to a healthcare laboratory for testing. Specimen labeling is critical in the testing process. A correctly labeled specimen will be accepted by laboratories for proper testing. However, an incorrectly labeled specimen will require the laboratory to proceed with testing until further clarification can be provided. Specimen labels have standard requirements that include providing at least two patient identifiers (date of birth, social security number, etc.) in order to prevent misidentification, writing with indelible ink to prevent information from fading or being erased, legibly printing specimen information to prevent patient identifiers from being illegible and using materials that are built to last in the harshest environments.
