What is the purpose of labeling blood samples immediately after collection?

Labeling blood samples immediately after collection is vital to ensure accurate identification and traceability. This is critical in a clinical setting to prevent mix-ups or misidentification, which can lead to incorrect diagnoses or inappropriate treatments. Proper labeling provides essential information, such as the patient's name, identification number, date, and time of collection. This not only ensures the integrity of the sample but also helps in tracking its journey through the testing process, maintaining a clear chain of custody that is crucial for accurate medical record-keeping and patient safety. Thus, immediate and accurate labeling is a standard practice in phlebotomy to uphold the quality and reliability of laboratory results.
