Orsin Medical Technology presents its high-performance ESR Blood Collection Tubes, engineered to deliver precision and reliability in erythrocyte sedimentation rate testing. Designed for the Westergren method, our tubes ensure accurate diagnostic results with enhanced safety and efficiency.
ESR tubes incorporate advanced engineering to deliver superior clinical performance:
| Feature Category | Technical Specification | Clinical Value |
|---|---|---|
| Contamination Prevention | Closed vacuum system; direct blood transfer to anticoagulant tube | Eliminates operator exposure; reduces lab contamination; complies with biosafety standards |
| Operational Efficiency | Distinctive black cap; pre-measured anticoagulant; ready-to-use | Streamlines workflow; reduces sampling errors |
| Result Precision | 0.129mol/ L(anticoagulant:blood=1:4); concentration-controlled | Ensures consistent anticoagulation; prevents ESR deviations |
| System Compatibility | Compatible with major automated ESR analyzers (e.g., ESR-30/40); LIS/HIS integration | Enhances lab efficiency; reduces transcription errors |
| Interference Resistance | Specialized anticoagulant minimizes effects of icteric/hemolyzed/lipemic samples | Expands detectable sample range; improves reliability in pathological states |
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.*
