LIVE WEBINAR: September 23rd, 2026, 1:00pm ET
EDTA remains an effective anticoagulant when blood can be processed promptly, but many real-world workflows impose practical limitations. Batching, transport, staffing gaps, remote-site collection all introduce delay. During that window, the sample continues to change. Cells can break down and release material into plasma that was never present at the moment of collection, making the biological signal harder to interpret. This webinar examines what happens in a tube of blood after draw, why the composition at draw time is the reference point that matters, and how pre-analytical conditions shape results across multi-analyte workflows.
The discussion will begin with cell-free DNA, where white blood cell stability is critical in limiting genomic DNA background, then extend to more delay-sensitive analytes including cell-free RNA, extracellular vesicles, and select protein markers. Attendees will learn how to recognize when variability may reflect collection or handling artifact rather than true biology and what to specify up front when designing a pre-analytical protocol.
