The erythrocyte sedimentation rate (ESR) is one of the most commonly utilized non-specific markers of inflammation or underlying disease processes in clinical practice. Initially described by Robert Fåhraeus in the early 20th century, the ESR is a simple test that is used as a screening tool and monitoring tests for various inflammatory conditions. The test measures the rate at which red blood cells sediment in a period of one hour, with elevated rates indicating the presence of inflammatory mediators that cause red blood cells to stick together.
Automated Esr Analyzer
Traditionally, Esr Analyzer were performed manually using specialized tubes and equipment. However, in recent decades there have been significant advances in the automation of ESR measurement using specialized analyzers. Key features of modern automated Westergren ESRs include:
Dilution and sample handling: Automated analyzers are able to efficiently dilute whole blood samples and distribute them into measurement cuvettes. This streamlines the pre-analytical processing compared to manual methods.
