**I. Product Principle and Core Value**
This blood collection tube employs a **dual-action design**: a silicone-based clot activator coating on the inner wall accelerates blood coagulation, while an inert hydrophobic gel is pre-installed at the tube bottom. Its core value lies in:
- **One-Step Separation and Preservation**: After centrifugation, the gel forms a stable physical barrier between the serum and blood cell layers, effectively preventing re-mixing and substance exchange during storage and transport.
- **Ensures Long-Term Serum Stability**: The physical barrier significantly reduces the release of intracellular components into the serum (e.g., potassium ions, lactate dehydrogenase), providing better analyte stability in refrigerated conditions.
- **Enables an Efficient "Ready-to-Use" Workflow**: The serum is stably isolated above the gel layer and can be directly aspirated by analytical instruments, eliminating additional aliquoting steps. This greatly enhances laboratory efficiency and reduces operational contamination risks.
**II. Main Areas of Application**
This product is suitable for all testing projects requiring **high-quality, highly stable serum**, particularly for:
- **Routine Biochemical Tests** (e.g., liver and kidney function, lipids, glucose, electrolytes)
- **Immunological and Serological Tests** (e.g., hormones, tumor markers, antibody detection)
- **Therapeutic Drug Monitoring**
- **Batch Health Check-ups and Projects Requiring Prolonged Serum Transport or Storage**
**III. Product Specifications and Operational Procedures**
- **Additive Composition**: Silicone-based clot activator (wall coating) + inert separation gel (tube bottom)
- **Identification Feature**: Typically identified by a **yellow cap**
- **Standard Operating Procedure**:
1. **Collection and Mixing**: Immediately after blood collection, gently invert the tube 5–8 times to ensure thorough contact between the clot activator and the blood.
2. **Clotting and Centrifugation**: Allow the tube to stand upright for 20–30 minutes for complete clotting, then centrifuge at the recommended force (typically 1300–2000 RCF) for 10–15 minutes.
3. **Barrier Formation**: During centrifugation, the gel migrates to form a stable barrier between the serum and the clot, achieving one-step separation.
**IV. Quality Control and Comparative Advantages**
Compared to traditional clot activator tubes (red cap), gel & clot activator tubes (yellow cap) offer the following outstanding advantages:
- **Enhanced Compatibility with Automation**: The serum layer is clear and free from cellular interference, making it more suitable for continuous aspiration by fully automated biochemical and immunoassay analyzers.
- **Superior Sample Quality**: Effectively reduces interference from factors such as hemolysis and lipemia in testing.
- **Streamlined Preprocessing Workflow**: Reduces the need for sample aliquoting, thereby decreasing laboratory personnel workload and biosafety risks.
