Cell-Free DNA BCT®
StreckFor In Vitro Diagnostic Use. Cell-Free DNA BCT is a direct-draw venous whole blood collection device intended for the collection, stabilization and transport of venous whole blood samples for use in conjunction with cell-free DNA next generation sequencing assays For that have been cleared or approved for use with samples collected into the Cell-Free DNA BCT device. Performance characteristics of this device have only been established on the Guardant360 CDx assay.
Nucleic Acid BCT™
StreckNucleic Acid BCT is a direct draw venous whole blood collection device that maintains draw-time concentrations of cell-free DNA, cell-free RNA and extracellular vesicles for up to 7 days when stored at room temperature.? Once isolated from stored plasma, cell-free DNA and cell-free RNA are suitable for many downstream applications. Nucleic Acid BCT is currently available in a 5 mL volume. 10 mL volume is coming soon.
