Total CE Hours: 1 Credit Hour

Pace Course #: 586-2518-25

Course Description: Aliquoting and sample division are essential steps in the laboratory process, serving as the bridge between specimen collection and accurate analysis. Each time a specimen is divided into smaller portions, the potential for labeling errors, contamination, or misidentification increases. This course provides a focused and practical overview of the protocols that ensure precision, traceability, and consistency during the aliquoting process. Participants will explore how careful attention to labeling and accuracy protects both patient safety and data reliability within the clinical laboratory environment.

The course begins with a review of specimen handling fundamentals, outlining the chain of custody from collection through analysis. Learners will examine how proper aliquoting supports the separation of plasma, serum, and other sample fractions for multiple diagnostic purposes while maintaining specimen integrity. The content emphasizes the role of standardized labeling practices, clear identification of secondary containers, and verification procedures that reduce the risk of pre-analytical errors.

Practical guidance is provided on the use of barcode systems, secondary tube labeling, and documentation techniques that promote compliance with institutional and regulatory standards. Scenarios highlight the consequences of inaccurate aliquot labeling, including rejected specimens, delayed test results, and potential misdiagnosis. By understanding these real-world impacts, participants will gain a stronger sense of accountability and the importance of accuracy in every step of the process.

Attention is also given to preventing cross-contamination and ensuring proper mixing, storage, and transfer of specimens. Best practices for maintaining sample stability and preventing degradation are reviewed, reinforcing how precision in aliquoting directly supports diagnostic accuracy. Participants will also learn the value of effective communication between phlebotomists, laboratory technicians, and clinical teams in maintaining specimen integrity and ensuring test reliability.

By the end of this course, participants will understand that accurate aliquoting and labeling are not simply technical steps, but critical quality assurance measures. Through consistent adherence to protocol, proper documentation, and attention to detail, laboratory professionals can minimize errors, enhance workflow efficiency, and uphold patient trust. This course reinforces that the quality of laboratory results begins long before analysis, within the care, accuracy, and professionalism applied during the earliest stages of specimen handling and division.
