    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

    ConditionClinical Utility
    InfectionsBacterial TB → ESR ↑↑ >100 mm/h
    Autoimmune diseasesActive RA → ESR ↑ (combined with CRP)
    MalignanciesMultiple 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
    20–50Mild elevation (e.g., chronic inflammation)
    >50Significant 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
