What is an example of a unique identifier for a specimen label?

A unique identifier for a specimen label is crucial for ensuring that the specimen can be correctly matched to the patient and their medical records. The medical records number or date of birth serves this purpose effectively because these identifiers are unique to each patient and are less likely to be duplicated across different patients. This unique information helps avoid confusion that may arise from common names or similar demographic data.

In contrast, using just the patient's name might introduce ambiguity, especially in healthcare settings where many patients might share the same last name. Similarly, a physician's name does not provide a direct link to the specimen being tested, as multiple specimens could be collected under the same physician. The sample collection date alone may not distinguish a specimen from others collected around the same time from different patients.

Thus, a date of birth or a medical records number is the most reliable and unique identifier, reinforcing the accuracy and integrity of the testing process.
