Erythrocyte Sedimentation Rate (ESR) - Westergren's Method

What is Erythrocyte Sedimentation Rate (ESR)?

Erythrocyte Sedimentation Rate (ESR), commonly known as sed rate test, is a blood test used to detect inflammation in the body. This useful diagnostic tool uses Westergren's technique as the widely accepted standard to quantify the rate at which red blood cells sink at the bottom of a test tube over a one-hour period.

Why ESR Test is Performed ?

The ESR test assesses the rate at which red blood cells (erythrocytes) settle. The Westergren's method is one of the most common methods used for measuring ESR and is considered the standard method. This test can be a useful method for diagnosing and monitoring various conditions such as infections, autoimmune diseases, and cancers.


  • Profile Name: Erythrocyte Sedimentation Rate (ESR) - Westergren's Method
  • Sample Type: Blood
  • Preparations Required: There is no special preparation required for this test
  • Report Time: 4 hours

Erythrocyte Sedimentation Rate Procedure

ESR blood uses Westergren's technique. A blood sample is analysed in a tall, thin test tube during an ESR test, and the rate of red blood cell settlement is observed. Red blood cells settle slowly under normal conditions, but inflammation causes them to clump together, increasing the settling process. ESR westergren blood test is very useful in detecting and monitoring inflammatory diseases such as polymyalgia rheumatica, rheumatoid arthritis, and systemic lupus erythematosus. While this test has long been used in medical settings, its lasting significance stems from its simplicity and effectiveness. It functions as a general screening tool, encouraging additional research when abnormal values are detected.

Frequently Asked Questions

The ESR test is frequently used to help in the diagnosis of inflammatory disorders such as arthritis or vasculitis. It is also useful for tracking the progression of inflammatory diseases.

ESR test evaluates how far red blood cells pass through a test tube in one hour (in millimetres). When there is inflammation, some proteins cause red blood cells to stick together and fall faster than normal.

If you are experiencing symptoms of an inflammation illness, a physician may recommend an ESR. The signs you have can differ depending on the disease, however elevated sed rate symptoms may include: Headaches, Weight loss, Joint stiffness, Unexplained fever, Loss of appetite, Anemia, Neck or shoulder pain

No, fasting is not required for the ESR test.

Normal values can range from 0-29 mm/hr for women and 0-22 mm/hr for men. However, normal ranges might vary slightly depending on the laboratory that analyzes the blood sample.

A High Erythrocyte Sedimentation Rate indicates inflammation, infection, or autoimmune conditions.

An ESR higher than 100 mm/hr is seen as concerning, showing there may be a serious inflammation or infection present.

ESR can be influenced by various factors such as age, gender, anemia, pregnancy, infections, inflammatory conditions, and specific medications.
