Specialized Blood Collection Tubes
Extended Stability Tubes
Specialized blood collection tubes such as Streck Cell-Free DNA BCT® and Qiagen PAXgene Blood RNA tubes are commonly used in fresh whole blood collections when extended specimen stability is required. These tubes stabilize nucleic acids and prevent cellular degradation during storage and transport, maintaining specimen integrity for up to 14 days at room temperature. These extended stability formats provide flexibility in processing timelines and are essential for liquid biopsy applications, gene expression studies, and transcriptomic analyses.
Standard Anticoagulant Tubes
Fresh whole blood collected in standard anticoagulant tubes—EDTA (purple top), heparin (green top), or sodium citrate (blue top)—provides viable cells for immediate processing upon arrival. EDTA tubes are most common for general cellular analyses, flow cytometry, and cell isolation. Heparin tubes preserve cell viability for functional assays and culture applications. Citrate tubes are used for coagulation studies and platelet function assays. These standard tubes require rapid processing (typically within 24-48 hours) to maintain optimal cell viability, making overnight delivery essential for preserving functional cellular characteristics.
Tube Selection Guidance
MT Group works with you during study design to determine the optimal tube types for your specific downstream applications. Considerations include analytical endpoints (cfDNA vs. cellular RNA vs. viable cells), processing timelines at receiving facilities, storage requirements, and compatibility with specific assay platforms. Our sites are equipped to collect blood into multiple tube types during single visits, enabling parallel analyses from the same subjects when study designs require both cellular and molecular endpoints.

What Our Clients Say
Frequently Asked Questions - Fresh Whole Blood Collections
Why are fresh whole blood collections limited to US sites?
Fresh whole blood requires overnight delivery to maintain cellular viability and nucleic acid integrity. International shipping timelines involving customs clearance and extended transit times would compromise cell function, making these collections feasible only within the US where overnight FedEx delivery can reliably deliver specimens the day after collection.
What volume of blood can be collected per subject?
Blood collection volumes depend on study requirements and can range from single tubes (typically 2-10mL) to multiple tubes across different tube types. Larger volume collections (e.g., 30-40mL total) are feasible when multiple analyses are required from the same subject. MT Group works with you during study design to determine appropriate collection volumes based on downstream analytical needs while ensuring subject safety and compliance with phlebotomy guidelines.
Can multiple tube types be collected from the same subject?
Yes, sites routinely collect blood into multiple tube types during single phlebotomy sessions. For example, a subject might provide EDTA tubes for flow cytometry, PAXgene tubes for gene expression, and Streck cfDNA tubes for liquid biopsy analyses. This enables comprehensive multi-parameter studies from individual subjects while minimizing subject burden.
How quickly must specimens be processed upon arrival?
Processing timelines depend on tube type. Standard anticoagulant tubes (EDTA, heparin, citrate) should be processed within 24-48 hours of collection for optimal cell viability. Specialized tubes like PAXgene and Streck cfDNA provide extended stability (up to 14 days at room temperature), offering more flexibility in processing schedules. MT Group provides guidance on processing timelines specific to your tube selections and analytical requirements.
What happens if FedEx delivery is delayed?
While FedEx overnight delivery is highly reliable, occasional delays can occur due to weather or logistical issues. If delivery delays compromise specimen viability for your research, you are not charged for those specimens. MT Group monitors shipments and communicates proactively about any delivery issues.
