Product Details
Prothrombin Time Blood Collection Tube
Product Positioning
Specialized vacuum tube for coagulation testing (light blue stopper), serving as the gold-standard tool for thrombotic and hemostatic screening.
Core Mechanism
3.2% Sodium Citrate
Precise chelation of calcium ions (Ca²⁺), inhibiting coagulation cascade
*Critical ratio control: Anticoagulant:Blood=1:9*
*＞10% deviation causes falsely prolonged PT/APTT*
Key Features
*Silicone-coated interior minimizes platelet activation (ISO 6710 compliant)*
*Vacuum accuracy ≤3% deviation (CLSI H21-A5 certified)*
Pre-filled lyophilized anticoagulant for instant mixing
Core Applications
| Test Panel | Clinical Significance |
|---|---|
| PT (Prothrombin Time) | Warfarin monitoring/Liver function |
| APTT (Activated Partial Thromboplastin Time) | Heparin therapy/Intrinsic pathway |
| Coagulation Factor Assays | Hemophilia diagnosis |
Critical Warnings
⚠️
Underfilling (90% volume): PT prolongation ≥20% (may cause false heparin resistance)
⚠️
*Gently invert 5-8 times immediately (vigorous shaking activates platelets)*
Technical Advantages
Foundation for International Normalized Ratio (INR)
Enables cross-lab PT comparability (WHO-certified system)
Optimal for automated analyzers
*Fibrin-free plasma after high-speed centrifugation (15000×g, 5min)*
