ESR Test in Chennai

ESR (Erythrocyte Sedimentation Rate) Test in Chennai

For dependable and accurate ESR (Erythrocyte Sedimentation Rate) test in Chennai, Unittas Hospital provides efficient blood testing services to measure how quickly red blood cells settle at the bottom of a test tube, serving as a non-specific indicator of inflammation in the body.

The ESR normal range varies by age and gender: typically less than 15 mm/hr for men under 50, less than 20 mm/hr for women under 50, less than 20 mm/hr for men over 50, and less than 30 mm/hr for women over 50, with lower values (often 0–10 mm/hr) in children. Results are reported in millimetres per hour (mm/hr) using the standard Westergren method.

What is the Erythrocyte Sedimentation Rate (ESR) Test?

The Erythrocyte Sedimentation Rate (ESR) test assesses the rate at which red blood cells (erythrocytes) settle in a vertical tube over one hour. In the presence of inflammation, proteins like fibrinogen cause red blood cells to clump (rouleaux formation), making them heavier and settle faster, resulting in a higher ESR value.

This test is a helpful screening tool but not diagnostic on its own. It is commonly ordered to:

Detect or monitor inflammatory conditions

Support evaluation of infections, autoimmune diseases, or certain cancers

Track disease activity or response to treatment in conditions like rheumatoid arthritis or temporal arteritis

Assist in investigating unexplained symptoms such as persistent fatigue or fever

ESR Test Procedure

A small blood sample is drawn from a vein in your arm into a tube containing an anticoagulant (usually sodium citrate). The sample is placed in a tall, narrow Westergren tube and left upright for one hour. The distance the red blood cells fall is measured in mm/hr. No special preparation like fasting is required, though inform your doctor of recent illnesses, medications, or pregnancy, as these can influence results.

Understanding Your ESR Results

Normal or low ESR: Suggests little to no significant inflammation.

Elevated ESR: Indicates possible inflammation or other underlying issues; the higher the value, the greater the inflammatory activity. Extremely high levels (e.g., over 100 mm/hr) often point to serious conditions.

High ESR causes and treatment depend on the underlying reason, identified through further tests and clinical evaluation. Common causes include infections (bacterial, viral), autoimmune disorders (rheumatoid arthritis, lupus), inflammatory conditions (polymyalgia rheumatica, giant cell arteritis), certain cancers, anaemia, kidney disease, or even normal states like pregnancy. Treatment targets the root cause—e.g., antibiotics for infections, anti-inflammatory drugs or immunosuppressants for autoimmune diseases, or supportive care for chronic conditions.

High ESR symptoms are not specific to the test itself but relate to the provoking condition, such as joint pain and swelling, unexplained weight loss, persistent fever, fatigue, muscle aches, headaches, or night sweats. The esr test range helps gauge severity but must be interpreted alongside symptoms, history, and other investigations like CRP, full blood count, or imaging.
