When should blood collection tubes be labeled?

Blood collection tubes should be labeled after the specimen is collected to ensure that the information matches the sample accurately at the point of collection. This practice minimizes the risk of labeling errors that could result in misidentification of the specimen, which is critical for proper diagnosis and treatment. By labeling the tube immediately following specimen collection, the phlebotomist can confirm the patient's details, such as name and other identifying information are correctly associated with that specific sample.

Labeling the tube at this stage eliminates confusion that could arise if labels are placed before the sample is collected or during the process, as changes may occur after the specimen is taken. This process is essential for maintaining the integrity and traceability of the sample throughout the testing phase.
