ESR Blood Collection Tube with Room-Temperature Storage Bionic Active Membrane and Black Cap for Clinical Diagnostics

Orsin Medical Technology ESR Blood Collection Tubes

Orsin Medical Technology presents its high-precision Erythrocyte Sedimentation Rate (ESR) Blood Collection Tubes, engineered for accuracy and reliability in clinical diagnostics.

These vacuum-evacuated tubes are specifically designed for the precise measurement of the Erythrocyte Sedimentation Rate, a critical marker for detecting and monitoring inflammatory activity, infections, and chronic diseases.

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:

• Optimized Anticoagulant: Pre-filled with a 3.2% concentration of Tri-Sodium Citrate, ensuring the ideal blood-to-anticoagulant ratio for consistent and clinically accurate ESR results.

• International Compliance: Features a distinct black closure for instant, unambiguous identification according to global ISO 6710 standards, enhancing safety and workflow efficiency in the lab.

• Superior Clarity: Manufactured from high-quality, clear glass or PET plastic for excellent sample visibility and minimal interference.

• Safety and Reliability: Each batch undergoes rigorous quality control to ensure sterility, consistent vacuum pressure, and clot-free sample collection.
