ESR Tube

ESR Tubes are specially designed for the determination of the Erythrocyte Sedimentation Rate (ESR) using the Westergren method. These tubes contain 3.8% sodium citrate solution as an anticoagulant to prevent clotting,

Usage
  • Used for: ESR (Erythrocyte Sedimentation Rate) testing
  • Application: General inflammation testing, autoimmune disorders, infection diagnosis, chronic disease monitoring
  • Common in: Pathology labs, hospitals, diagnostic centers, research labs
  • Preparation: • Confirm tube sterility and expiration. • Select correct citrate concentration (commonly 3.8%).
  • Collection Procedure: • Collect blood using a sterile technique. • Fill to the marked line to maintain the 4:1 blood-to-additive ratio. • Gently invert the tube 8–10 times to mix properly.
  • Testing: • Let the sample stand vertically for 1 hour in an ESR stand. • Measure the height of the clear plasma above the sedimented RBCs
  • Precautions: • Underfilling or overfilling may lead to inaccurate results. • Use immediately after collection or within 2 hours for optimal accuracy. • Store at room temperature (2–25°C) and avoid freezing.
  • Disposal: • Dispose of used tubes in accordance with biohazard waste protocols.

Note: Overfilling or underfilling may affect test accuracy.
