Introduction to Whole Blood Collection Tube
A Whole Blood Collection Tube is a specialized medical device designed to collect and preserve unaltered blood specimens for diagnostic testing, eliminating the need for manual separation of plasma or cells. These tubes ensure the integrity of blood components, providing a non-polluting and non-differential original specimen critical for accurate medical analysis.
Key Features and Benefits
-
Preserves Blood Integrity
The tube's interior is pre-coated with additives (e.g., anticoagulants) that prevent clotting and maintain the natural state of blood cells, ensuring reliable results for hematological and genetic tests.
-
Two Primary Types
- EDTA Tube (Purple Cap): Contains ethylenediaminetetraacetic acid (EDTA), a chelating agent that binds calcium ions to prevent coagulation. Ideal for clinical hematology tests, including complete blood counts (CBC), blood smears, and flow cytometry.
- ESR Tube (Black Cap): Sodium citrate-based, optimized for measuring erythrocyte sedimentation rate (ESR), a marker of inflammation.
-
Precision Coating Technology
Our automated sampling instruments apply additives uniformly to the tube's inner wall, ensuring rapid mixing with blood upon collection. This precision enhances anticoagulation efficiency and minimizes variability between samples.
-
Safety and Convenience
EDTA tubes feature a secure closure design that allows direct loading into analyzers without uncapping, reducing the risk of contamination and exposure to biohazards. This design streamlines laboratory workflows and enhances operator safety.
Applications
- Clinical Hematology: EDTA tubes are standard for routine blood examinations, providing stable specimens for up to 24 hours.
- Molecular Diagnostics: Preserves DNA/RNA integrity for genetic testing.
- Blood Banking: Supports cross-matching and antibody screening.
Quality Assurance
Each tube undergoes rigorous testing to ensure compatibility with automated analyzers and adherence to international standards (e.g., ISO 6710). The additives are formulated to minimize interference with biochemical and immunological assays, ensuring reliable results across diverse testing platforms.
By combining advanced coating technology, safety features, and specimen stability, Whole Blood Collection Tubes deliver a critical solution for modern healthcare, enabling accurate and efficient diagnostic testing.
