ALCOR Scientific has made a significant advancement in the field of diagnostic testing by extending the stability of blood samples used for erythrocyte sedimentation rate (ESR) tests from just four hours to an impressive 28 hours. This breakthrough, announced on September 16, 2025, addresses a long-standing issue in laboratories where timely processing of blood samples is critical for accurate diagnoses.
ESR tests are essential for detecting and monitoring various health conditions, including infections, autoimmune disorders, and certain cancers. Traditionally, blood samples for ESR testing must be either tested or refrigerated within four hours to ensure their accuracy. However, in many cases, samples may endure long transportation times or delays before reaching the laboratory, leading to potential inaccuracies in test results.
The new family of iSED ESR analyzers developed by ALCOR Scientific utilizes innovative technology that significantly enhances the integrity of blood samples. By measuring red blood cell aggregation, a crucial step in the sedimentation process, these analyzers allow samples to remain at room temperature for up to 28 hours without compromising their quality. This expansion of the time frame not only improves laboratory efficiency but also minimizes the need for repeat blood draws, which can be uncomfortable for patients.
In addition to the enhanced room temperature stability, the iSED analyzers also extend the refrigerated sample stability from 24 hours to 48 hours. This dual improvement offers laboratories greater flexibility in managing their workflows while ensuring reliable and accurate results.
Jim Post, CEO of ALCOR Scientific, emphasized the importance of this development: “ESR is one of the most frequently ordered tests globally, yet conventional testing methods put laboratories in a constant race against the clock. By extending sample stability to 28 hours, our analyzers give labs the flexibility they need to operate more efficiently while ensuring more accurate results and sparing patients from the discomfort of unnecessary repeat draws. It’s a win for both labs and patients.”
