If a patient's name is not located on the requisition order, which of the following is the next acceptable way to identify the patient in the hospital?

Choice A reason:
The date of birth is a common identifier, but it is not unique to an individual, as multiple patients may share the same birth date. While it is useful in conjunction with other identifiers, on its own, it does not provide a definitive identification.

Choice B reason:
The record number, often referred to as the medical record number, is a unique identifier assigned to each patient within a healthcare system. It is used to track patient information across different visits and services, making it the most reliable standalone identifier if the patient's name is not available.

Choice C reason:
An address can change over time and may not be unique, especially in large apartment buildings or for patients who are homeless or transient. It is also not specific enough to reliably identify a patient, as multiple individuals can reside at the same address.

Choice D reason:
The social security number is a unique identifier, but due to privacy concerns and the risk of identity theft, it is not the preferred method for patient identification in healthcare settings. Additionally, not all patients may have a social security number, such as non-residents or newborns.

Choice A Reason:
The timeline of the individual prior to specimen collection is important for context but is not typically part of the chain of custody documentation. The chain of custody focuses on the handling of the specimen rather than the activities of the individual before the collection.

Choice B Reason:
The identity of each person who handles the specimen is a critical element of the chain of custody. This information ensures that the specimen can be tracked at every stage from collection to analysis, and any potential tampering can be identified and addressed.

Choice C Reason:
While the physical and mental status of the individual may be noted in medical records or police reports, it is not a standard part of the chain of custody for a blood alcohol test. The chain of custody's purpose is to track the specimen, not the condition of the individual.

Choice D Reason:
The condition of the specimen every hour is not required in the chain of custody documentation. What is necessary is the documentation of any changes in the condition of the specimen that could affect the integrity of the results, such as temperature excursions or signs of tampering.
