Know More About the ESR (Erythrocyte Sedimentation Rate) Test
The ESR (Erythrocyte Sedimentation Rate) test measures how quickly red blood cells (erythrocytes) settle to the bottom of a test tube over one hour. When inflammation is present, certain proteins in the blood cause red cells to clump together and fall faster — resulting in a higher ESR reading.
The Westergren method is the standard technique used by most accredited labs. Normal ESR values are approximately 0–15 mm/hr for men and 0–20 mm/hr for women, though ranges vary slightly by age and lab. Values above normal are non-specifically elevated — this means a high ESR indicates that something is causing inflammation, but does not identify the cause on its own.
ESR is commonly ordered to investigate unexplained fever, persistent fatigue, joint pain, or as a monitoring tool in known inflammatory or autoimmune conditions — including rheumatoid arthritis, lupus, temporal arteritis, inflammatory bowel disease, and chronic infections. It is also used as a basic screening marker alongside the complete blood count.
Delhi's pollution load, high prevalence of chronic infections and large population with autoimmune conditions make ESR one of the most routinely ordered inflammation markers in the city. HealthVas lets you compare the ESR (Erythrocyte Sedimentation Rate) Test across NABL-accredited labs serving Delhi across South Delhi, Dwarka, Rohini, East Delhi and the central districts, book the lowest accredited price, and have the sample collected free at home.
Who Should Get an ESR Test
- People with unexplained fever or prolonged illness – A persistently elevated temperature without a clear cause is one of the most common reasons ESR is ordered — it indicates an ongoing inflammatory or infectious process.
- Anyone with joint pain, stiffness or suspected autoimmune disease – ESR is a first-line test in the workup for rheumatoid arthritis, lupus and other inflammatory arthropathies — it helps confirm active inflammation and monitors disease activity.
- People with persistent fatigue or unexplained weight loss – These non-specific symptoms often accompany chronic inflammation or infection. An elevated ESR helps direct further investigation.
- Patients with known inflammatory or autoimmune conditions – In established rheumatoid arthritis, lupus, inflammatory bowel disease or vasculitis, periodic ESR checks monitor disease activity and treatment response.
- Routine health screening alongside CBC – ESR is frequently included in comprehensive annual health checks or fever panels as an adjunct to the full blood count.
- Delhi residents investigating unexplained inflammation, fever or autoimmune symptoms – Delhi's pollution and high burden of chronic infections make ESR a frequent and valuable first-line inflammatory screen.
How to Prepare
No fasting or special preparation is required for an ESR test. You can eat and drink normally before giving the sample.
Wear half-sleeved or easily rolled-up clothing for easy venous access. Continue all medications as usual unless your doctor advises otherwise. Note that pregnancy, obesity, and some medications can raise ESR independent of inflammation — inform the lab of relevant factors.
HealthVas partner labs offer free home sample collection across Delhi-NCR — a trained phlebotomist visits your home or office at a time slot you choose, so there is no travel and no waiting room. Reports are delivered digitally and a branded copy can be shared directly on WhatsApp.
Why Compare Lab Prices on HealthVas?
Multiple NABL-accredited partner labs offer the ESR (Erythrocyte Sedimentation Rate) Test on HealthVas, and the price for the exact same test can differ widely from one lab to the next. Delhi has the densest concentration of NABL-accredited labs in the NCR — the price spread for the same test between cheapest and most expensive lab is often the widest here, making comparison the single biggest lever on what you pay.
NABL accreditation is the baseline standard for diagnostic accuracy in India — it certifies that a lab's equipment, reagents and reporting meet national quality benchmarks. Many partner labs additionally hold NABH, ISO or CAP certification, which add stricter internal quality controls. HealthVas shows you the accreditation alongside the price for each lab so you are comparing like with like, not just chasing the lowest number.
Unlike single-lab booking sites that only ever show you their own rate, HealthVas puts the accredited options side by side on one page. You see the lowest available price, the report turnaround, and whether free home collection is included — then book the lab that fits your budget and timeline.
ESR Test — What to Know Before Booking
The ESR test measures a single parameter — the sedimentation rate in mm/hr. It is most meaningful when interpreted alongside clinical findings and other tests, particularly CRP, CBC and organ function markers. On HealthVas you can compare the ESR price across NABL labs and book the lowest accredited rate with free home sample collection.
Frequently Asked Questions
Common questions for this test.
What does the ESR test measure?
It measures how fast red blood cells settle in a tube over one hour. A faster-than-normal sedimentation rate indicates inflammation somewhere in the body, though it does not identify the specific cause.
What is the normal ESR range?
Approximately 0–15 mm/hr for men and 0–20 mm/hr for women using the Westergren method. Ranges increase slightly with age. Your lab report will show the reference range used.
Do I need to fast for an ESR test?
No. Fasting is not required. You can eat and drink normally before the test.
What is the price of the ESR test?
It starts at ₹120 on HealthVas, with the lowest current rate from HealthFirst. Prices vary across NABL-accredited partner labs — the live price for each is shown on the page.
Is home sample collection available?
Yes. Free home sample collection is available across Delhi-NCR at a time slot you choose.
How long do reports take?
Most partner labs deliver the ESR result within a few hours to 24 hours. Each lab's turnaround is shown next to its price.
What does a high ESR mean?
An elevated ESR indicates active inflammation but does not tell you the cause. It is investigated further with CRP, CBC, and tests specific to the suspected condition.
Is ESR the same as SED rate?
Yes. ESR, SED rate, erythrocyte sedimentation rate and Westergren sedimentation rate all refer to the same test.
Is ESR included in a CBC test?
Not always. The complete hemogram (CBC+ESR) includes it, but a plain CBC does not. Check whether your CBC order includes ESR or needs to be added separately.
Why compare ESR test prices across labs?
Even for a simple test, prices differ across NABL-accredited labs. HealthVas shows accredited options side by side so you book the lowest price with a suitable report time.
Do I need a prescription to book?
No prescription is required to book an ESR test on HealthVas. Discuss results with your doctor for clinical interpretation.
Are the labs NABL-accredited?
Yes — every partner lab listed is NABL-accredited, with any NABH or CAP certification shown on the lab card.
