I. Product​ Core FeatureDual Protection for High-Quality Samples: It not only achieves efficient anticoagulation through EDTA to prevent blood coagulation from affecting tests, but also maintains the integrity and activity of target cells relying on cell protection technology, solving the problem that samples in conventional blood collection tubes are prone to failure.
Scenario Adaptability and Strong Stability: It can adapt to different transportation conditions (such as short-term transportation at room temperature). Within the specified storage time, cell morphology and molecular information (such as DNA and RNA) remain stable, reducing the sample loss rate.
Easy Operation and Universal Compatibility: It adopts the standard blood collection tube specification and is compatible with conventional blood collection equipment. No additional operation procedures are required, and the laboratory can directly use it for subsequent tests after receiving it, improving work efficiency.
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

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

Storage Requirements
Store in a dry, cool environment at 2–25℃; avoid direct sunlight, high temperature (above 30℃) and humidity (relative humidity >80%) to prevent degradation of the cell protection formula and anticoagulant.
Do not freeze the product. Freezing may cause tube breakage or damage to the inner coating, affecting sample stability.
Keep the tubes in their original packaging until use to avoid contamination and light exposure.
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.
