Our 5ml EDTA K2/K3 Blood Collection Tube is a specialized device engineered for precise hematology testing, designed to preserve the integrity of blood cells and ensure accurate cellular analysis. Formulated with either EDTA K2 (dipotassium ethylenediaminetetraacetate) or EDTA K3 (tripotassium ethylenediaminetetraacetate)—a gold-standard anticoagulant—it binds calcium ions to prevent blood clotting, maintaining the natural morphology of red blood cells (RBCs), white blood cells (WBCs), and platelets.
The tube’s 5ml volume is optimized for routine hematology workflows, providing sufficient sample for complete blood counts (CBC) and differential leukocyte counts. Crafted from medical-grade PET or glass, it features a smooth inner wall to minimize cell adhesion and damage, ensuring cells remain intact during collection, storage, and analysis. Its color-coded cap (typically purple or lavender, per international standards) allows instant identification in busy labs, reducing the risk of sample mix-ups.
Sterile, pyrogen-free, and compatible with automated hematology analyzers and manual microscopy, this tube seamlessly integrates into lab protocols. Whether for routine screenings or specialized cellular studies, it delivers consistent sample quality—critical for reliable hematological diagnosis.
- Superior Anticoagulation: EDTA K2/K3 effectively chelates calcium to prevent clotting, preserving the natural shape and size of blood cells (RBCs, WBCs, platelets) for up to 24 hours at 2–8°C—essential for accurate cell counting and morphology assessment.
- Optimized Volume: 5ml capacity provides ample sample for comprehensive hematology tests (e.g., CBC, differential counts), reducing the need for re-collection.
- Cell Integrity Protection: Smooth inner wall (PET/glass) minimizes cell adhesion and hemolysis, ensuring cells remain viable and morphologically intact for analysis.
- Instant Recognition: Purple/lavender cap (industry standard for EDTA tubes) enables quick differentiation from other blood collection tubes, lowering handling errors in high-throughput settings.
- Broad Compatibility: Works with automated hematology analyzers (e.g., for CBC) and manual microscopy, fitting seamlessly into routine and specialized lab workflows.
- Routine Hematology Testing: Complete Blood Count (CBC), including hemoglobin, hematocrit, RBC/WBC/platelet counts, and differential leukocyte analysis.
- Cellular Morphology Studies: Evaluation of abnormal cell shapes (e.g., sickle cells, target cells) in conditions like anemia, leukemia, or infections.
- Pre-Surgical Screening: Assessment of blood cell counts to evaluate patient readiness for surgery (e.g., platelet levels to assess bleeding risk).
- Chronic Disease Monitoring: Tracking changes in blood cell counts for patients with conditions like leukemia, thrombocytopenia, or bone marrow disorders.
