Product Description
ESR & Erythrocyte Sedimentation Rate & Anticoagulation & Standardized Testing
Core Functions
- Anticoagulation
- Key additive: 3.2%-3.8% Sodium Citrate
- Blood-to-anticoagulant ratio: 4:1 (e.g., fill to "2mL" mark = 1.6mL blood + 0.4mL anticoagulant)
- Mechanism: Chelates calcium ions → blocks coagulation cascade → maintains blood liquidity
- Standardized Testing
- Specialized dimensions (Ø 2.5mm × 200mm) → Complies with Westergren method (ICSH standard)
Primary Applications
1. Monitoring Inflammatory Diseases
| Condition | Clinical Utility |
|---|---|
| Infections | Bacterial TB → ESR ↑↑ >100 mm/h |
| Autoimmune diseases | Active RA → ESR ↑ (combined with CRP) |
| Malignancies | Multiple myeloma → Persistent ESR ↑ (therapy monitor) |
2. Procedure (ICSH Protocol)
- Fill blood to the calibration mark
- Invert mix 8 times
- Place vertically in Westergren rack
- Stand undisturbed at RT for 60 min
- Measure plasma interface drop (mm) = ESR value
3. Result Interpretation
| ESR (mm/h) | Clinical Implication |
|---|---|
| <20 (M) / <30 (F) | Normal |
| 20-50 | Mild elevation (e.g., chronic inflammation) |
| >50 | Significant elevation (active infection/tumor) |
Critical Notes
1. Error Control
Fill volume deviation: ±10% error → ESR deviation up to 30% (Must fill exactly to the mark!)
Time sensitivity: Test >4h post-collection → RBC morphology alters → Falsely ↓ESR
2. Interfering Factors
| Factor | ESR Effect | Solution |
|---|---|---|
| Anemia (Hct<30%) | Falsely ↑ | Corrected ESR = ESR × [0.73+Hct] |
| Refrigerated sample | Falsely ↓ | Equilibrate to RT for 30 min |
| Underfilled tube | Clot formation | Discard and recollect |
