Liquid Sodium Citrate (3.2%) Safety-engineered, latex-free stopper ESR 1.28ML

Orsin Medical Technology ESR Blood Collection Tubes

Engineered for precision in hematological testing, the Orsin ESR Tube ensures accurate Erythrocyte Sedimentation Rate results. It comes pre-filled with the exact volume of liquid sodium citrate anticoagulant to guarantee the critical 4:1 blood-to-anticoagulant ratio, which is essential for test reliability.

Crafted with clinician safety and workflow in mind, the tube features a robust safety cap and is manufactured from high-clarity material for easy sample evaluation. Orsin's ESR Tube is the trusted choice for laboratories dedicated to delivering consistent and accurate patient diagnostics.

Product Highlights: Technological Innovation Ensures Accuracy

ESR tubes incorporate advanced engineering to deliver superior clinical performance:

Usage Precautions: Standardized Operations Ensure Reliability

3.1 Pre-collection Preparation

• 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.

3.2 Blood Collection Protocol

• 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.

3.3 Post-collection Handling

• 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.*
