Labeling blood samples immediately after collection is crucial to prevent mix-ups and ensure accurate testing. This practice helps to verify that the sample corresponds correctly to the patient from whom it was taken. Any delay in labeling can increase the risk of misidentification, leading to potentially serious consequences, such as administering the wrong treatment based on incorrect lab results. Accurate labeling at the point of collection ensures the integrity of the sample and the reliability of the subsequent test results, thereby maintaining patient safety and promoting effective healthcare.

While keeping samples organized, facilitating quicker processing, and ensuring that samples are sent to the same location are important factors in laboratory efficiency and workflow, they do not address the primary concern of accurate identification and the direct association between a sample and the patient. Immediate labeling is fundamentally about safeguarding the precision of the testing process.
