EDTA Blood Collection Tube with Precise Anticoagulation
Product Characteristics
EDTA blood collection tubes (purple cap) utilize dipotassium or tripotassium ethylenediaminetetraacetate (EDTA-K₂ or EDTA-K₃) as the core anticoagulant, featuring:
- Precise Anticoagulation Mechanism: Chelates calcium ions (Ca²⁺) in blood to block thrombin activation, achieving complete anticoagulation while maximally preserving blood cell morphology.
- Optimized Physical Design:
- High-transparency PET plastic or glass tube with mechanical strength and light resistance
- Pre-filled precise anticoagulant dosage (1.5-2.2 mg EDTA/mL blood), vacuum accuracy ≤±5%
- Safety & Quality Control:
- Gamma-irradiated sterilization (8-25 kGy), controlled endotoxin levels
- ISO13485/CE compliant; standardized purple cap for rapid identification
Application Scenarios
Primarily for hematological testing, with specific applications:
| Test Category | Suitable Applications | Restrictions |
|---|---|---|
| Basic Hematology | Complete Blood Count (CBC), Hemoglobin (Hb), Blood Typing, Reticulocyte Count | Coagulation Tests (e.g., PT/APTT), Platelet Function Testing |
| Specialized Tests | Glycated Hemoglobin (HbA1c), Hemoglobin Electrophoresis, Flow Cytometry | Electrolytes (Ca²⁺/K⁺/Na⁺)/Iron Assays, Alkaline Phosphatase, Creatine Kinase |
| Molecular Biology | DNA/RNA Extraction, Pathogen Nucleic Acid Testing (with stabilizers) | PCR (EDTA may inhibit enzyme activity) |
Note: EDTA tubes cannot be used for electrolyte, trace element, or coagulation testing due to chelation interference.
Usage Protocol & Specifications
| Procedure | Requirements | Key Operational Notes |
|---|---|---|
| Pre-collection | Check expiration date/vacuum integrity | Storage: 2-25°C, dark, dry conditions |
| Collection & Mixing | Gently invert 5-8 times immediately post-draw | Excessive force -> hemolysis; insufficient mixing -> microclots; accelerate if >25°C |
| Testing Window | Routine tests: complete within 24h | WBC count: 48h at 4°C; Platelet count: ≤24h at 4°C |
| Centrifugation | Not for direct centrifugation | Plasma separation requires gel separator (0.8-1.2 g/tube) |
Precautions
- Anticoagulant Risks:
- Overfill (>2.2 mg/mL): RBC shrinkage/platelet swelling -> morphology distortion
- Underfill: Inadequate anticoagulation -> microclots -> instrument obstruction
- Sample Handling:
- Do not reuse tubes or mix additives
- Blood volume ≤ labeled capacity (e.g., ≤5.5 mL for 5 mL tube)
- Safety: EDTA is corrosive; rinse skin/eyes immediately with water if contacted
FAQs
- EDTA-K₂ vs. EDTA-K₃?
- Solubility: K₃ dissolves easier -> liquid pre-filled tubes; K₂ -> spray-dried plastic tubes
- Performance: Comparable anticoagulation, but K₃ excess may cause platelet satellitism (pseudothrombocytopenia)
- Causes of Pseudothrombocytopenia? Solutions?
- Causes: EDTA-induced platelet aggregation (~0.1% incidence) or neutrophil adhesion (satellitism)
- Resolution: Recollect using sodium citrate tube
- Can tubes with microclots be used? No. Microclots indicate anticoagulation failure -> recollect with thorough mixing
- Suitable for glucose testing? Compatible with sodium fluoride (2-4 mg/mL blood) to inhibit glycolysis; validate system compatibility
Clinical Note: EDTA tubes remain the gold standard for CBC. For abnormal cases (e.g., suspected platelet disorders), parallel testing with alternative anticoagulants is recommended.
