2ml ESR Blood Collection Tube with Sodium Citrate Anticoagulant

Orsin Medical Technology ESR Blood Collection Tubes

Orsin Medical Technology's ESR Blood Collection Tubes are designed for precise and efficient erythrocyte sedimentation rate (ESR) testing in clinical settings. These tubes ensure reliable results through strict adherence to international standards and advanced manufacturing processes.

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.*

Technical Specifications: Standard-Compliant Parameters

Key Features:

• Anticoagulant Formula: Pre-filled with 3.2% sodium citrate (ICSH-compliant) to maintain optimal blood-to-anticoagulant ratio (4:1).

• Distinct Design: Black cap for instant recognition and reduced risk of sampling errors (per ISO 6710).

• Material Excellence: Crafted from high-quality PET or glass to ensure sample integrity and clarity.

• Rigorous Quality Control: Sterilized, endotoxin-tested (<0.5 EU/mL), and validated for performance (CLSI H21-A5).

• Automation Compatibility: Seamlessly integrates with automated ESR analyzers for streamlined processing.
