ESR Vacuum Blood Tubes

ESR (Erythrocyte Sedimentation Rate) Vacuum Blood Tubes are specialized blood collection tubes used to measure the rate at which red blood cells (erythrocytes) settle at the bottom of a test tube over a specific period, typically one hour. This rate is an important diagnostic indicator of inflammation and certain medical conditions.ESR tubes play a critical role in diagnosing and monitoring conditions involving inflammation, and their precise design ensures reliable and consistent test results.

Key Features


  • Specific Volume:ESR tubes are precisely calibrated to collect a specific blood volume to maintain an accurate blood-to-anticoagulant ratio (4:1). This ratio is critical for accurate ESR test results.
  • Vacuum Design: The vacuum feature ensures the correct blood volume is drawn into the tube automatically, which simplifies the process and minimizes variability in test results.
  • Monitoring Disease Progression:ESR tests can be used to monitor the progression of inflammatory diseases or the effectiveness of treatment over time.
  • Simple and Inexpensive: The ESR test is easy to perform and cost-effective, making it a widely used test in many healthcare settings.
