Labeling the specimens immediately after collection is crucial for ensuring the accuracy and reliability of test results. This practice minimizes the risk of sample mix-up and ensures that each specimen can be accurately identified and linked to the correct patient. Proper labeling typically includes the patient's name, identification number, the date and time of collection, and the type of specimen, which is all essential for tracking and maintaining the integrity of the testing process.

In contrast, keeping tubes open could lead to contamination or evaporation, underfilling tubes might affect the test results because certain tests require specific volumes for accurate analysis, and allowing blood to settle for 30 minutes is not a standard practice for specimen collection and could impact the results depending on the tests being performed. Therefore, immediate labeling serves as a best practice in maintaining a reliable and organized laboratory workflow.
