Company Profile

ESR & Erythrocyte Sedimentation Rate & Anticoagulation & Standardized Testing

Core FunctionsAnticoagulation
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 Applications1. Monitoring Inflammatory DiseasesConditionClinical Utility
InfectionsBacterial TB → ESR ↑↑ >100 mm/h
Autoimmune diseasesActive RA → ESR ↑ (combined with CRP)
MalignanciesMultiple myeloma → Persistent ESR ↑ (therapy monitor)
2. Procedure (ICSH Protocol)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 InterpretationESR (mm/h)Clinical Implication
<20 (M) / <30 (F)Normal
20–50Mild elevation (e.g., chronic inflammation)
>50Significant elevation (active infection/tumor)
Critical Notes1. Error ControlFill 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 FactorsFactorESR EffectSolution
Anemia (Hct<30%)Falsely ↑Corrected ESR = ESR × [0.73+Hct]
Refrigerated sampleFalsely ↓Equilibrate to RT for 30 min
