Liyhium Heparin / Sodium Heparin Blood Collection Tube Sprecise K⁺/ Na⁺quantification

Product Introduction: Lithium Heparin/Sodium Heparin Blood Collection Tubes By Orsin
Lithium Heparin (Li Heparin) and Sodium Heparin (Na Heparin) tubes utilize ultra-pure anticoagulants to block the coagulation cascade, designed for tests requiring plasma samples. Li Heparin tubes are optimal for electrolyte, blood gas, and molecular biology tests, while Na Heparin tubes excel in emergency biochemistry and coagulation screening. Both employ ultra-smooth walls + spray-coated technology to ensure rapid, homogeneous anticoagulant dissolution, inhibiting thrombin activity within 5 seconds and preventing microclot formation.

Key Features & Selling Points

1. Zero Metal Interference (Critical Advantage of Li Heparin)

   • Lithium salt replaces sodium salt, eliminating Na⁺/K⁺ measurement errors (critical in panic value scenarios), ensuring:
     ▶ Blood potassium deviation <0.1 mmol/L
     ▶ Blood sodium CV <1.5%

2. Rapid Plasma Separation Technology

   • Centrifugation Efficiency: 3,000 rpm × 10 min → plasma yield (30% faster than EDTA tubes)

   • Barrier Purity: Inert polyester gel barrier achieves >99% clearance of fibrinogen residues.

3. Broad-Spectrum Anticoagulant Activity

   Parameter	Li Heparin Tube	Na Heparin Tube
   Anticoagulant Target	Inhibits Factor Ⅱa, Ⅹa	Potently inhibits Factor Ⅱa
   Compatible Tests	Blood gas, PCR, electrolytes	STAT biochemistry, thrombin time
   Interference Avoidance	No Na⁺/K⁺ contamination	Prevents calcium chelation

4. Performance Optimization for Emergency Testing

   • Immediate anticoagulant activation: Invert mix 8 times after draw, completes anticoagulation in 30 sec;

   • Plasma stability: Maintains pH and enzyme activity for 24h at 4°C (supports retesting).

Application Scenarios

• Li Heparin: ICU blood gas analysis, genetic testing, precise K⁺/Na⁺ quantification;

• Na Heparin: ER cardiac enzyme panels, liver function, D-dimer rapid screening.

⚠️ Contraindications:

• Na Heparin tubes are prohibited for plasma Ca²⁺/Li⁺ tests (anticoagulant interference);

• EDTA tubes are preferred for flow cytometry (heparin causes cell aggregation).
