How Do You Spell WESTERGREN?

Westergren is a term that refers to a specific laboratory method used to measure the rate of sedimentation of red blood cells in blood samples. This technique is named after its developer, Dr. Westergren, who introduced it in the early 20th century as a means to diagnose and monitor various blood disorders.

In the Westergren method, a sample of blood is collected into a specialized tube known as a Westergren tube, which is marked with numerical divisions. The tube is then left undisturbed in an upright position for a specific period, usually one hour, to allow the red blood cells to settle and form a column at the bottom. After the allotted time, the height in millimeters of the clear plasma above the column of settled red blood cells is measured. This height, known as the erythrocyte sedimentation rate (ESR) or Westergren sedimentation rate, provides an indirect indication of inflammation or infection in the body.

The Westergren method is widely used in clinical practice to evaluate and monitor a variety of conditions such as autoimmune disorders, infections, and certain types of cancers. It is a reliable and relatively simple test that can provide valuable information to physicians about a patient's health status. However, it does not provide a specific diagnosis but rather serves as a supplementary tool to aid in the diagnostic process. The Westergren method has been standardized and has specific reference ranges depending on age and gender, making it a valuable tool in assessing and monitoring various health conditions.
