Description

ESR & Erythrocyte Sedimentation Rate & Anticoagulation & Standardized Testing

Core Functions

  1. 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.

  2. 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)

  1. Fill blood to the calibration mark → 2. Invert mix 8 times → 3. Place vertically in Westergren rack → 4. Stand undisturbed at RT for 60 min → 5. 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
