Product Description: Green-Cap Vacuum Blood Collection Tube with Lithium Heparin

Below are its primary functions and applications:

Key Features (产品特点)

1. Rapid Anticoagulation with Lithium Heparin

    

   Pharmaceutical-grade lithium heparin efficiently binds calcium ions to prevent blood clotting, preserving sample integrity for up to 4 hours at room temperature—critical for maintaining stable electrolyte and biochemical analyte levels.
2. Precision Vacuum Design

    

   Pre-evacuated to a calibrated negative pressure, ensuring consistent blood draw volumes (eliminating underfill/overfill) and streamlining collection in time-sensitive scenarios, such as emergencies.

Applications

• Emergency Biochemistry Testing: Ideal for rapid analysis of critical analytes (e.g., glucose, urea, creatinine) in urgent cases like trauma, sepsis, or metabolic crises.
• Electrolyte Monitoring: Preserves stability of sodium, potassium, chloride, and bicarbonate levels—essential for evaluating hydration status, renal function, or acid-base balance.
• Routine Clinical Chemistry: Suitable for non-coagulation-dependent assays in outpatient or inpatient settings, supporting general health screening and disease management.
• Point-of-Care Testing (POCT): Compatible with portable analyzers, enabling on-site electrolyte and biochemical testing in emergency departments, ambulances, or remote clinics.

1. Hematology (Limited Application):

   • Although heparin is an anticoagulant, it is not ideal for Complete Blood Count (CBC) or blood smear preparation because it causes:

     • Altered Leukocyte and Platelet Morphology: Heparin may cause leukocyte clumping and abnormal platelet morphology, interfering with microscopic examination.
