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

Labeling blood samples immediately after collection serves the crucial purpose of avoiding misidentification and ensuring accurate testing. Proper identification is fundamental in the laboratory setting, as it allows healthcare professionals to correctly match patient information with their respective specimens. This practice is essential for several reasons.

Firstly, accurate labeling helps in preventing medical errors that can arise from sample mix-ups. Misidentified samples can lead to incorrect diagnoses, inappropriate treatments, or even severe patient harm. By labeling samples right after collection—when the healthcare provider is still knowledgeable about the context and patient details—it minimizes the risk of confusion or errors.

Secondly, proper labeling contributes to the overall integrity of the testing process. It ensures that the results generated by the laboratory can be reliably traced back to the correct patient, supporting effective patient care.

While the other options offer related benefits—such as tracking samples or maintaining sample freshness—none directly address the primary importance of preventing misidentification, which fundamentally supports the validity and reliability of the testing outcomes.
