Product Name: Vacuum Blood Collection Tube (Lithium Heparin LH)
Certification: CE, ISO 13485, NMPA Import License No. 20172222314
Intended Use:
For collection, anticoagulation, and processing of venous/arterial blood samples in:
Clinical chemistry (electrolytes, renal/liver function, lipids)
Emergency testing (rapid plasma separation for critical assays)
Key Advantages:
Minimal Ion Interference
Lithium heparin minimizes bias in Na⁺/K⁺ measurements vs. sodium heparin, critical for accurate electrolyte reporting
Faster Turnaround Time
Eliminates clotting wait (30 min for serum tubes); plasma separation within minutes enables 1-hour reporting for STAT tests (e.g., cardiac markers, thyroid function)7.
Optimized Anticoagulation
Spray-dried coating ensures uniform heparin distribution; 5-8 gentle inversions achieve complete mixing, preventing microclots
Gel Barrier Compatibility
Optional gel separator (e.g., BD Barricor™) stabilizes plasma for 24h at room temperature by blocking cellular metabolism
Safety & Precision Engineering
Pre-set vacuumguarantees correct blood-to-additive ratio; safety caps reduce needlestick risks
Infectious disease diagnostics (e.g., hepatitis, HIV serology)
Hemorrheology studies (plasma viscosity analysis)
