- Explain how transparency and manufacturer partnerships improve quality, consistency, and decision-making confidence in specimen management.
- Evaluate blood collection tubes beyond cost and commodity assumptions, incorporating clinical impact and risk into decision-making.
- Assess the potential risk points when using a blood collection device that has not been cleared for a specific purpose.
Roundtable presenters Nick Fingland, PhD, PMP, Senior Director, R&D Operations and Science, BD, and Chris Farnsworth, PhD, D(ABCC), Section Head of Clinical Chemistry, Professor of Pathology and Immunology, Washington University School of Medicine.
