What is an Esr Analyzer?

An Westergren ESR, also known as an erythrocyte sedimentation rate (ESR) analyzer, is a medical device used to measure the ESR in a blood sample. The ESR is commonly used as a non-specific medical test to detect levels of inflammation in the body. An elevated ESR often indicates the presence of diseases such as infections, cancers, autoimmune disorders, and inflammatory conditions.

Esr Analyzer work by automatically timing how long it takes for red blood cells in a blood sample to settle in a tall, thin Westergren pipette tube. Under normal conditions, red blood cells are negatively charged and repel each other, preventing them from settling quickly. However, during inflammation certain proteins in the blood plasma lose their negative charge. This allows red blood cells to clump together, making them heavier and causing them to settle faster. By precisely timing this sedimentation process, Westergren ESRs can provide a measurement of a patient's ESR level.

Advantages of Automated Esr Analyzer

In the past, ESR tests were performed manually by medical laboratory technicians who had to visually inspect and time blood samples settling in pipettes. This manual process was time-consuming and prone to human errors. Modern automated Westergren ESRs offer several key advantages over the traditional manual method:
