The Erythrocyte sedimentation rate (ESR) test is a simple blood test that measures the rate at which red blood cells settle to the bottom of a tube. This test is commonly used to detect and monitor inflammation in the body, as an increased rate of sedimentation suggests the presence of an underlying inflammatory condition. It is a non-specific test, meaning it doesn't diagnose a specific condition but can aid in the diagnosis or monitoring of various inflammatory diseases such as arthritis, infection, or autoimmune disorders. The ESR test is often performed alongside other diagnostic tests to provide a more comprehensive picture of a patient's health.

The erythrocyte sedimentation rate, abbreviated as ESR, is determined by the rate at which red blood cells (RBCs) settle within a test tube.The ESR test is employed to evaluate inflammation within the body. As numerous conditions can lead to an abnormal ESR result, this test is generally utilized in conjunction with other diagnostic tests to diagnose and monitor various diseases.
The primary objective of an ESR test is to identify abnormal inflammation levels in the body. ESR measurement is predominantly employed for the diagnosis and ongoing monitoring of various health conditions.
An ESR test might be suitable when you experience unexplained symptoms such as fever, muscle or joint pain, or other issues lacking a clear cause. In these instances, ESR testing is typically complemented by other diagnostic tests such as: complete blood count, a comprehensive metabolic panel, and arthritis tests, among others. These tests collectively assess your overall health and search for indications of particular health issues.
Diagnostic evaluation is the process of identifying the underlying cause of a patient's symptoms. Since various health issues can lead to an abnormal ESR test result, the test on its own cannot definitively diagnose conditions. Nevertheless, when employed in conjunction with other diagnostic tests, an ESR test can assist in identifying infections, autoimmune diseases, blood disorders, kidney disease, and a multitude of other health problems.
Monitoring involves regularly evaluating a patient's health following a diagnosis. Periodic ESR testing may be employed to track changes in inflammatory health conditions over time. It also serves the purpose of gauging a patient's response to treatments for specific disorders.
Consider an ESR test if you are experiencing unexplained symptoms such as fever, muscle or joint pain, or other issues lacking a clear cause. In such cases, ESR testing is typically conducted alongside other assessments, including a complete blood count, comprehensive metabolic panel, and arthritis tests, to comprehensively evaluate your health and identify potential indicators of specific health concerns.
Furthermore, your healthcare provider may suggest an ESR test to monitor your health if you have a history of prior diagnoses or treatments for infections, autoimmune diseases, or other inflammatory health conditions.
Generally, an ESR test cannot be self-administered at home. Instead, it necessitates the expertise of a trained medical professional and must be carried out in a clinical setting, where the blood sample can be promptly analyzed following collection.
No specific test preparation is needed for an ESR test. However, you must inform your doctor about any medications or supplements you are currently taking, as certain substances can potentially influence your test results.
The ESR result is reported in millimetres per hour (mm/h) and signifies the rate at which the red blood cells (RBCs) in your sample descend toward the bottom of a test tube.
A universal definition of a normal ESR does not exist, as various factors such as age, sex, and other variables can influence ESR levels. Therefore, there is no single reference range applicable to all individuals.
Instead, the interpretation of ESR results is contingent on an individual's unique circumstances, which include their symptoms and the outcomes of any additional tests conducted.
An abnormally high ESR indicates that the RBCs descended more rapidly than expected. This typically occurs when the RBCs contain a higher amount of protein, causing them to aggregate.
Numerous conditions can lead to an elevated ESR. While it is most commonly associated with inflammatory conditions, it can also be linked to various other health issues.
