EDTA K2/K3 & PET Tube Body High-Precision Spraying Silicone-Coated Interior

EDTA K2/K3

1. International Standard Certifications

• CLSI H21-A5 & ISO 6710:2017:
  Prioritize K₂ as the "gold standard" for hematological testing¹⁸.

• EU CE Mark & China Class II Medical Device Approval:
  Ensures quality reliability (e.g., BD Vacutainer®®, Medico®® brands)²⁹.

2. Optimized Manufacturing Design

• Silicone-Coated Interior:
  US-imported silicone coating prevents cell adhesion/fibrin deposition, reducing hemolysis risk³⁵.

• High-Precision Spraying:
  Uniform anticoagulant distribution enables mixing via 5–8 gentle inversions (vs. ≥8 inversions for crystalline tubes with higher hemolysis risk)²⁷.

3. Durable & Safety-Compliant Materials

• PET Tube Body:
  High-temperature/corrosion resistance with optimal transparency for sample inspection³⁹.

• Butyl Rubber Stopper:
  Puncture resistance ≥40,000 cycles (exceeding GB standard of 20,000), reducing instrument probe wear³⁵.

Applications of EDTA Anticoagulated Blood Samples

1. Hematology Testing

   • Complete Blood Count (CBC) / Full Blood Count (FBC) and related parameters

   • Reticulocyte count

   • Erythrocyte sedimentation rate (ESR) - Note: Typically uses citrate tubes, but EDTA may be accepted by some labs

2. Morphological Examination

   • Peripheral blood smear evaluation (e.g., abnormal cell identification)

3. Hemoglobinopathy Studies

   • Hemoglobin electrophoresis (e.g., HbA2, HbF quantification)

   • Sickle cell screening

4. Molecular Diagnostics (DNA-Based Testing)

   • Genetic Mutation Analysis:

     • Inherited disorders (e.g., thalassemia, cystic fibrosis)

     • Pharmacogenomics (drug metabolism genes: CYP2C9, VKORC1, etc.)

   • Chromosomal Studies:

     • Karyotyping

     • Fluorescence in situ hybridization (FISH)

   • HLA Typing for histocompatibility (transplant matching)

   • Pathogen DNA Detection:

     • Quantitative viral load tests (e.g., CMV, EBV DNA)

   • Forensic Applications:

     • Paternity testing

     • Forensic identification (STR profiling)
