Our 1:9 Sodium Citrate Vacuum Blood Tube is a specialized collection device engineered for accurate coagulation testing, designed to preserve blood’s coagulation factors and ensure reliable results in hemostasis analysis. Pre-evacuated to a precise negative pressure, the tube guarantees consistent consistent blood draw volumes, eliminating underfill/overfill errors that could skew test outcomes.
The tube contains a buffered sodium citrate solution at a strict 1:9 ratio (citrate to whole blood), which binds calcium ions to prevent premature clotting—critical for maintaining the integrity of coagulation factors (e.g., fibrinogen, prothrombin). This standardized ratio adheres to international laboratory standards (e.g., CLSI guidelines), ensuring compatibility with automated coagulation analyzers and manual assays alike.
Crafted from medical-grade PET or glass, the tube features a smooth inner wall to minimize platelet activation and cell damage, while its color-coded cap (typically blue, per global conventions) enables instant identification in busy lab settings. Sterile, pyrogen-free, and pre-sterilized, it guarantees contamination-free sample collection, supporting accurate diagnosis in coagulation-related disorders.
Key Features
Precise 1:9 Ratio: Buffered sodium citrate solution in a 1:9 (anticoagulant to blood) ratio—clinically validated to preserve coagulation factors and prevent false results, aligning with global standards (e.g., CLSI).
Vacuum-Sealed Design: Pre-evacuated to ensure consistent blood fill volumes, reducing variability in test outcomes and streamlining collection workflows.
Sample Integrity Protection: Smooth inner surface minimizes platelet activation and hemolysis; sterile/pyrogen-free construction prevents contamination, critical for sensitive coagulation assays.
Instant Recognition: Blue cap (industry-standard for citrate tubes) allows quick differentiation from other blood collection tubes, reducing handling errors in high-throughput labs.
Broad Compatibility: Works seamlessly with automated coagulation analyzers (e.g., PT, APTT, INR tests) and manual methods, fitting into routine and specialized lab protocols.
Applications
Routine Coagulation Testing: Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT), International Normalized Ratio (INR) for monitoring anticoagulant therapy (e.g., warfarin).
Hemostasis Disorders: Diagnosis and management of bleeding disorders (e.g., hemophilia) or thrombotic conditions (e.g., deep vein thrombosis, DVT).
Pre-Surgical Screening: Evaluates coagulation status before surgeries to assess bleeding risk.
Anticoagulant Monitoring: Tracks the effectiveness and safety of blood-thinning medications, ensuring optimal dosing.
Trusted in hospitals, reference labs, and hematology clinics, this tube delivers consistency and accuracy—essential for guiding clinical decisions in coagulation-related care.
