EDTA Blood Collection Tube for Liquid Biopsy with Cell Protection

I. Product Features

Precision Anticoagulation Mechanism
- Utilizes potassium ethylenediaminetetraacetate (EDTA-K₂ or EDTA-K₃) to inhibit coagulation by chelating calcium ions, preserving blood cell morphology and quantitative integrity.
- Strict anticoagulant dosage of 1.5-2.2 mg/mL blood, ensuring optimal anticoagulation without under- or over-treatment.
Premium Materials & Craftsmanship
- Tube Material: High-clarity medical-grade PET plastic (lightweight, shatter-resistant) or glass (for large volumes), with silicone-coated interior to prevent cell adhesion and hemolysis.
- Sealing System: Butyl rubber stopper offers superior airtightness (>40,000 puncture tolerance), minimizing needle wear.
- Vacuum Accuracy: Imported equipment guarantees blood draw volume error ≤±5% (e.g., 1.9-2.1 mL for 2 mL tubes).
Standardization & Safety
- Purple cap (universal color code) for rapid identification.
- Gamma-irradiated sterilization, endotoxin-compliant, certified to ISO 13485 and CE standards.

II. Application Scenarios

Test Type	Specific Applications	Mechanism
Basic Hematology	Complete Blood Count (CBC), blood typing, erythrocyte sedimentation rate (requires dedicated tube)	Preserves cell morphology, prevents clotting interference
Specialized Tests	HbA1c, flow cytometry, pathogen nucleic acid testing (PCR)	Stabilizes RBC membranes, protects DNA/RNA integrity
Contraindications	Coagulation tests (PT/APTT), calcium/potassium ion assays, trace element analysis	EDTA chelation disrupts ion balance and clotting factor activity

III. Key Specifications

Parameter	K2/K3 EDTA Tube Specifications	Remarks
Volume Options	1-10ml (PET/GLASS)	Accommodates diverse sample volume needs
Anticoagulant Conc.	1.5-2.2 mg/mL blood	<1.5 mg/mL risks clotting; >2.2 mg/mL shrinks cells
Centrifugation	3500-4000 rpm × 5 min	Separates plasma/cellular layers

IV. Precautions

Collection Protocol
- Gently invert tubes 5-10 times immediately after draw—do not shake—to prevent microclots.
- Fill to marked volume: underfilling causes partial clotting; overfilling dilutes anticoagulant (causing pseudothrombocytopenia).
Sample Handling & Storage
- Time Sensitivity: Prepare blood smears within 2 hours; whole blood stored ≤6 hrs (RT) or ≤4 hrs (4°C)—prolonged storage alters cell morphology.
- Temperature: Ideal testing range: 18-22°C; extremes (>30°C or <15°C) affect cell volume.
Order of Draw
Follow sequence: Blood culture → Plain tubes → Citrate coagulation tubes → EDTA tubes to avoid cross-contamination.

V. Frequently Asked Questions (FAQs)

Microclots observed post-collection. Solution?

Cause: Inadequate/untimely mixing (especially at >25°C) or underfilled tube.

Action: Invert ≥8 times; ensure precise fill volume.

EDTA-K₂ vs. EDTA-K₃: Key differences?

Form: K₂ = crystals; K₃ = liquid spray (faster dissolution).
Impact: K₃ overuse dilutes samples (falsely lowers Hb); K₂ offers better batch consistency.

Suitable for coagulation tests?

No! EDTA chelates calcium, disrupting coagulation cascades. Use dedicated citrate tubes (blue cap) instead.

Causes/prevention of hemolysis?

Causes: Blood impacting tube bottom, violent mixing, premature refrigeration (<30 min post-draw).

Prevention: Angle tubes to let blood flow along walls; use large-bore needles; invert gently.

Preventing blood reflux infection?

Procedure: After draw → Remove tube first → Release tourniquet → Withdraw needle. Prevents negative-pressure backflow.
