When should the phlebotomist label the blood collection tubes?

The phlebotomist should label the blood collection tubes immediately after drawing the blood and before leaving the patient's side. This ensures that the correct patient information is associated with each sample and minimizes the risk of mix-ups or errors. The label should include essential information such as the patient's name, identification number, date, and time of collection. Proper labeling is crucial for accurate testing and patient safety.
