Orsin Medical Technology offers high-quality ESR (Erythrocyte Sedimentation Rate) blood collection tubes, designed to ensure accuracy and reliability in hematology testing. Our tubes contain a precise formulation of anticoagulants, such as sodium citrate, to maintain sample integrity and deliver consistent results for clinical diagnostics.
Engineered for convenience and safety, Orsin's ESR tubes feature user-friendly design, clear labeling, and compliance with international standards. Ideal for healthcare facilities and laboratories, they support efficient workflow and reduce preanalytical errors.

Usage Precautions: Standardized Operations Ensure Reliability
Tube Selection: Verify black-capped ESR-specific tubes contain 3.8% sodium citrate. Inspect for particulates, sedimentation, or cap looseness.
Storage Conditions: Store at 4-25°C. Avoid freezing (causes tube fracture) or high temperatures (degrades anticoagulant).
Patient Preparation: Collect blood from calm, preferably fasting patients. Note non-fasting status on requisition forms.
Order of Draw: Follow international sequence: blood culture → coagulation tubes → other anticoagulant tubes → ESR tubes (black cap). Prevents anticoagulant cross-contamination.
Exact Fill Volume: Draw precisely to fill line (typically 2mL). Underfilling causes false-low ESR; overfilling promotes microclot formation.
Mixing Technique: Gently invert 5-10 times immediately after collection. Avoid vigorous shaking to prevent partial anticoagulation or hemolysis.
Testing Timeline: Analyze within 2 hours. Delayed testing alters erythrocyte morphology. Store at 18-25°C if necessary (NEVER refrigerate).
Tube Orientation: Transport upright to avoid disturbing sedimentation.
Sample Rejection Criteria: Reject clotted, severely hemolyzed, improperly filled (>±10%), unlabeled, or damaged specimens.
*Note: 30% of ESR errors originate from pre-analytical issues, primarily inaccurate fill volumes and improper mixing.*
Precision Formula: Pre-filled 3.2% sodium citrate (4:1 ratio) for accurate Westergren ESR results.
Safety Design: Latex-free stopper with safety-engineered closure to prevent needlestick injuries.
Clear Scale: High-contrast 0-200 mm graduation for easy reading.
Ready-to-Use: Pre-vacuumed with consistent fill volume, reducing pre-analytical errors.
Quality Material: Inert glass/PET plastic ensuring sample integrity and clarity.
CE Certified: Complies with international IVD standards and sterility requirements.
