Phlebotomy Technician Practice Exam (NCPT/CPT)

Proper labeling of tubes is important to ensure accurate and safe testing procedures. However, labeling the tubes before performing a venipuncture can actually lead to errors and inaccuracies. It is important to label the tubes immediately after collecting the blood to ensure that the tubes are properly matched with the correct patient and testing requirements. Labeling the tubes before the venipuncture can result in pre-labeling errors or incorrect labeling of the tubes due to the distraction of performing the procedure.
