ESR Blood Test: Normal Erythrocyte Sedimentation Rate Result

Erythrocyte Sedimentation Rate (ESR, Sed Rate, Sedimentation Rate) is a laboratory blood test that indirectly measures the degree of inflammation in the body. It measures the rate of settling or sedimentation of red blood cells (erythrocytes) in a tall, thin tube of blood collected from a patient.

Proteins produced during inflammation cause erythrocytes to move close together and stack up in a group. When red blood cells are in group, they become heavier (denser) so they settle faster. The further erythrocytes settle and the faster they fall, the higher is the value of ESR. ESR blood test result is reported as how many millimeters of plasma (clear, yellowish fluid component of the blood) are present at the top of the thin tube in one hour.

Uses of Erythrocyte Sedimentation Rate (ESR)

ESR blood test helps in the diagnosis of conditions associated with acute and chronic inflammation such as infections, cancers, and autoimmune diseases. Although ESR blood test can tell that there is inflammation in the body, it cannot tell what condition or disease is causing the inflammation. Doctors use ESR blood test result in conjunction with other clinical findings, laboratory test results, and the patient’s health history in diagnosing the disease of a patient.

There are many conditions that may cause inflammation and increase ESR: rheumatoid arthritis, lupus, anemia, endocarditis, kidney diseases, osteomyelitis, tuberculosis, syphilis, thyroid disease, rheumatic fever, systemic body infection, giant cell arteritis, pregnancy, multiple myeloma, polymyalgia, vasculitis, and other inflammatory diseases.

There are also conditions that result in lower-than-normal ESR: sickle cell anemia, polycythemia, blood hyperviscosity, low plasma protein due to certain diseases, decreased blood fibrinogen levels (hypofibrinogenemia), and congestive health failure.

Normal Erythrocyte Sedimentation Rate (ESR)

There are two laboratory methods in measuring erythrocyte sedimentation rate: the Westergren and Wintrobe method. The Westergren method is used in most laboratories worldwide. Below are the normal ESR results using Westergren method (in millimeters per hour (mm/hr) :


-Less than 15 mm/hr for men under 50 yrs old

-Less than 20 mm/hr for women under 50 years old

-Less than 20 mm/hr for men over 50 yrs old

-Less than 30 mm/hr for women over 50 years old


  • 0-2 mm/hr for newborns
  • 3-12 mm/hr for children in neonatal and puberty stage

I wish I could answer your question, but I cannot give medical advice. Please talk to your doctor. I hope it is not something to worry about. I wish you good health. Thank you for visiting my site.

I am a 84yr. old male. Have Chronic Venous Insufficiencency being treated.
My ESR is 44mm/hr.
Would this be a cause of a elevated ESR?

Please talk to your doctor. Thanks.

Connie October 4, 2010 at 4:22 pm

Hi. I’m a 36 yr old lady which had a couple of blood tests the past few weeks. My esr went from 31 to 36 in a space of one week. WBC and neuts were high as well. Plus it says on my lab results monocytosis and esonophilia. What us your opinion on that?thanks.

R.F. Camat October 5, 2010 at 1:08 pm

Pls. talk to your doctor about this. I cannot give medical advice online. Thank you.

Fahi Sheikh October 5, 2010 at 11:07 am

hi, i am 27 years old girl, i have got a high ESR since 7 years ago, the only symtom that I have is rashes on my leg which apears whenever I stand oin my feet for a long time. i have ANA Positive as well.
I ‘m realy afraid of SLE.thank you for your cooments

R.F. Camat October 5, 2010 at 1:11 pm

There’s nothing to worry much on those rashes. Take note that being an ANA Positive doesn’t mean that you are going to have SLE. More tests are needed to diagnose SLE. Please talk to your doctor for more information. Thank you.

Please talk to your doctor about this. Thanks and good luck.

My ESR is 36 mm/1 hrs and my Lymphocytes 3.4 x10(9)/L while my Neutrophhils 3.2 x10(9)/L. What does this mean?

Deb December 25, 2010 at 5:23 am

What does an “indeterminate” rate of 6mm mean?

Midwest January 2, 2011 at 1:07 pm

Why does anemia cause an elevated SED rate?

ashutosh kumar January 21, 2011 at 4:24 pm

sir, my wife is pregnant and her esr is120mm/h. what are the possibilities and prevention for this?

Jack August 13, 2011 at 12:14 pm

An elevated ESR is a normal physiological response of pregnancy and should not cause any concern.
Any lab results need to be taken into account with other lab and clinical findings. So a single test outside of ‘normal refernce ranges’ should not cause too much concern, least of all a non-specific ancient test like an ESR.

Kelly January 28, 2011 at 1:03 am

I have an Sed Rate of 38MM. It has continued to steadily climb for the past 3 years. I started out as extremely anemic but, now have that under control…yet, the rate continues to climb. I have been under a doctor’s care and she seems to be out of ideas.
The biggest problem is my pain. I have horrible pain that generates from my bones. (A bone scan revealed nothing.) Recently, the pain was more than usual and I had the SR test done again and my Rate was higher than ever. Please help me to find something to look for that can connect the two: pain and the SR. I hurt so badly on days like that one that I just felt miserable. Please note if you have ever heard of such.

To All who sought answers to lab result as I Have:
Pleas go to Wikipedia for information about ESR, along with Google to research this Lab Result. It basically measures your red blood cell sedimentation rate, which is used to measure and detect the presence of inflammation in the body. The causes of that inflammation are described for various types of causes and usually part of a series of blood tests ordered by Physicians. Take all the information and do a Google and Wikipedia search for the results. In most cases, especially at Kaiser Permanente, short explanations about the use and indicator is given. Further research on your part will give you a better understanding of the ‘Range of results”. A conversation with your Medical Practitioner will give you more insight and is an effective way of getting professional advice. None of us, including myself, cannot advise you legally or medically because we are not Physicians, and, because they have the training we don’t to put all the results into a Correct perspective for your understanding. I’ve gotten more pre-appointment information this way and it helps me to focus on the question-answer session, with my Doctor, to understand the importance of his advise. With all good wishes and hopes for your better health..pjb

ESR can help in the diagnosis of condition associated with acute Chronic. but How can we know it is in chronic or acute phase ?
