What should be included when labeling a blood specimen tube?

When labeling a blood specimen tube, it is crucial to include the patient's name, date of birth (DOB), initials, as well as the date and time the sample was collected. This comprehensive labeling ensures accurate identification of the specimen, which is vital for proper diagnosis and treatment.

Including the patient's full name and DOB helps to avoid mix-ups between patients and ensures that the correct individual is linked to the specimen. The initials serve as an additional identifier, particularly useful when multiple staff members are collecting specimens. Recording the exact date and time of collection is essential for tracking changes in the patient’s condition over time and correlating lab results with clinical events.

In clinical settings, the accuracy of patient information is paramount to ensure patient safety and facilitate effective communication among healthcare providers. Therefore, option B encompasses all necessary details for proper identification and tracking of the specimen throughout the testing process.
