Introduction to Gel & Clot Activator Tube
A Gel & Clot Activator Tube is a specialized blood collection tube designed to facilitate the efficient separation and preservation of high-quality serum specimens for clinical biochemistry, immunology, and serology tests. Its primary function is to streamline the process of obtaining serum by accelerating blood clotting and physically separating serum from cellular components, ensuring optimal sample integrity for accurate diagnostic analysis.
Key Components and Mechanism
- Clot Activator: The tube contains an additive (e.g., silica particles or thrombin) that triggers rapid blood coagulation, shortening the time required for serum separation.
- Medical-Grade Gel: At the bottom of the tube lies a stable, inert gel layer. This gel is a pure substance with exceptional physico-chemical stability, resistant to degradation under high temperatures or pH fluctuations. During centrifugation, the gel forms a tight barrier between the serum (upper layer) and cellular components (lower layer), preventing re-mixing and ensuring clear serum separation.
Advantages
-
High-Quality Serum Production
The clot activator ensures complete blood coagulation, while the gel's stability and barrier function minimize contamination or degradation of serum components. This results in serum specimens free from cellular debris, ideal for sensitive laboratory assays.
-
Reduced Risk of Equipment Clogging
The gel's resistance to high-temperature decomposition and prevention of small molecule precipitation significantly decrease the likelihood of particulate matter entering testing equipment (e.g., analyzers or pipettes). This protects laboratory instruments from clogs, reduces maintenance needs, and enhances workflow efficiency.
-
Reliability and Consistency
The tube's standardized design and stable gel properties ensure consistent performance across batches, making it a trusted choice for clinical laboratories requiring reliable sample preparation.
Applications
Gel & Clot Activator Tubes are widely used in clinical settings for:
- Routine biochemistry tests (e.g., glucose, lipid panels, liver function tests).
- Immunological assays (e.g., antibody detection, tumor markers).
- Serological diagnostics (e.g., infectious disease screening).
By combining rapid clot activation with efficient serum separation, these tubes play a critical role in delivering timely and accurate diagnostic results, supporting effective patient care.
