Collection Tubes
Understanding Collection Tubes: The Foundation of Reliable Diagnostic Testing
In clinical diagnostics and molecular research, the collection tube is more than just a container — it’s the first step in protecting sample integrity. From routine chemistry panels to advanced oncology testing, the right tube ensures analytes remain stable from draw to analysis.
Why Tube Selection Matters
Different testing workflows require different additives, preservatives, and materials. Anticoagulants such as EDTA, heparin, and citrate each serve distinct purposes. Serum separator tubes support chemistry panels, while specialized stabilization tubes are designed to preserve circulating tumor DNA (ctDNA), RNA, or fragile biomarkers for extended transport times.
Improper tube selection can compromise:
- Nucleic acid stability
- Cell-free DNA recovery
- Analyte concentration
- Downstream assay accuracy
