Core Labs Launching New Method For ESR

The Core Laboratories in the Department of Pathology and Laboratory Medicine is launching a new method for erythrocyte sedimentation rate (ESR) with ALCOR iSED® instrumentation, which allows for rapid, automated analysis of ESR using lavender top tubes. The iSED rapid methodology will replace ESR measurement on Excyte® 40 analyzers beginning Monday, Aug. 6.

The average bias between the methods is ~0.4 mm/hr. Deming regression analysis shows a linear correlation with a slope of 0.997, y-intercept of 0.5 mm/hr, and a correlation coefficient (R) of 0.9847 (the method correlation is shown in the figure below). Therefore, the two methods correlate very well to one another. iSED will replace Excyte methodology (current platform).

For ESR by iSED specimens should be collected in lavender top (13x75 mm) tubes and submitted for analysis immediately. Samples are stable at room temperature for four to six hours and at 4°C for 24 hours.

The new reference intervals are as follows:

  • Men under 50 y/o < 15 mm/hr
  • Men over 50 y/o < 20 mm/hr
  • Women under 50 y/o <20 mm/hr
  • Women over 50 y/o < 30 mm/hr
