Challenging Times in the Laboratory Call for Simple Solutions

Erythrocyte Sedimentation Rate (ESR) is a common laboratory test used to help determine if a patient has a condition that causes inflammation or help monitor patients with known inflammatory conditions. 48 million of these tests are performed in the US each year.* Traditional ESR testing is done using a technique called the Westergren method. More modern ESR tests can shorten the time to result but still require significant hands-on time. iSED® analyzers utilize capillary photometry and help optimize laboratory efficiency by providing a result within 20 seconds with minimal hands-on time.​

Introducing iSED® Technology

ALCOR® Scientific’s iSED® capillary photometry technology is based on syllectometry. Photometric rheology is used to quantify the rouleaux formation, which is the earliest and most critical phase of red blood cell sedimentation. Red blood cells are injected into the iSED® analyzers’ flow cell which causes them to disaggregate. The flow cell sensors capture the difference in light transmission over time as the injected red blood cells begin to re-aggregate. The technical innovation of ALCOR® Scientific ESR analyzers consists of “directly” measuring the aggregation of the red blood cells, whereas the traditional methods “indirectly” measure the aggregation of the red blood cells by recording the length at which the red cells settle in a Westergren tube. Like traditional ESR testing, iSED® results are provided in mm/hr. iSED® technology is highly correlated to the Westergren method, and test results are available in just 15-20 seconds without the drawbacks and inconvenience of traditional ESR testing.

iSED® Analyzer Results are Less Affected by Variables That Impact Traditional ESR Testing​

Traditional ESR testing is commonly affected by different environmental variables as well as variables within the sample. The iSED® sample is analyzed within seconds in a closed environment, limiting potential impact of environmental​ factors, and sampling is done by the instrument, eliminating the potential for human error. Hematocrit and MCV, which impact traditional ESR test results, also have a more limited effect on iSED® results.
