How Much Does The Test Cost
The price of an ESR test varies based on where you have the test done and whether you have health insurance. The cost of the test may increase if you have other tests performed along with an ESR. For example, an ESR test through Testing.com costs $39.
If you want to know more about the cost of the procedure and how much your insurance covers, contact your insurance company. If you do not have any kind of health insurance coverage, you can ask the testing facility about any available financial assistance programs for the uninsured.
Is Esr 35 High
Of the patients with nonmalignant disease, 9.6 percent had an ESR of less than 10 mm/hr and 25.6 percent a rate of less than 20 mm/hr. Thus, in about a quarter of the patients, the ESR was below the top normal level for the elderly. Moreover, the ESR may be as high as 35–40 mm/hr in healthy aged persons.
Other Tests You May Need
The sed rate test can only tell your doctor that you have inflammation somewhere in your body. It can’t show where the inflammation is or what caused it. Your doctor may also test for your erythrocyte sedimentation rate or C-reactive protein to help make a diagnosis. Both are acute phase reactants or inflammatory markers which can help point to a diagnosis or help follow treatment in a diagnosis. You will still need imaging or even biopsyies to make a specific diagnosis.
Talk to your doctor about the results of your sed rate test, and any other tests you have. Make sure you understand what the results mean, and how they’ll affect your treatment.

Causes Of High Esr Levels
The high levels of ESR can indicate the development of cancerous tissues, especially in cases where no inflammation in the body is found. The ESR levels may exceed the optimum values in case of some commonly associated medical conditions like:
- Ischemia, that is, lack of blood in a tissue
- Tissue injury
- Thyroid disease
- Autoimmune diseases like rheumatoid arthritis, lupus, Waldenstroms macroglobulinemia, polymyalgia rheumatic, temporal arteritis, allergic or necrotizing vasculitis, and hyperfibrinogenemia
- Infections like rheumatic fever, systemic infection, skin infection, tuberculosis, bone infection, and heart infections like pericarditis, myocarditis, and endocarditis.
Why Is A Sed Rate Test Done
A sed rate test may be done when your doctor suspects you have a condition causing inflammation. Sed rate is called a nonspecific test because it does not diagnose specific illnesses but adds to the information about the presence and levels of inflammation.
A sed rate may be ordered to help in diagnosing and monitoring conditions including:
- Acute infection, such as tuberculosis and tissue necrosis
- Chronic infection

What Do The Results Of The Esr Test Mean
Red blood cells that travel up to 20 millimeters per hour is considered normal, says rheumatologist Steffan Schulz, MD, assistant professor of clinical medicine with Penn Medicine in Philadelphia.
In people with autoimmune disease, the sed rate can go up to about 150 millimeters per hour, and the more elevated it is, the higher the inflammation in the body is. It might set off higher alarms if it comes back in the hundreds and youre investigating whether someone has an autoimmune disease, says Dr. Schulz. If it comes at 31, it might not give a lot of ammunition.
What Are Normal Sedimentation Rates
- The normal sedimentation rate for males is 0-15 millimeters per hour,
- for females, it is 0-20 millimeters per hour.
- The sedimentation rate can be slightly elevated in the elderly.
- Falsely low sedimentation rates can occur in the blood of people with leukemia or polycythemia rubra vera.

Diagnosing Conditions That Cause Inflammation
The ESR test can be used to help your doctor diagnose conditions that cause inflammation, such as:
This test involves a simple blood draw. It should take only a minute or two.
The blood sample is taken to a lab, where your blood will be placed in a long, thin tube in which it sits for one hour. During and after this hour, the laboratory professional processing this test will assess how far the RBCs sink into the tube, how quickly they sink, and how many sink.
Inflammation can cause abnormal proteins to appear in your blood. These proteins cause your RBCs to clump together. This makes them fall more quickly.
Why Would I Need This Test
You might need an ESR test if your doctor suspects that you have an infection or an illness related to inflammation. As ESR is not specific, other tests might be needed to identify the location and cause of the inflammation or infection.
ESR is particularly useful in detecting two specific illnesses: giant cell arteritis and polymyalgia rheumatica.

What Is A Sedimentation Rate
A sedimentation rate is a common blood test that is used to detect and monitor inflammation in the body. The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the speed that the red blood cells in a tube of blood fall to the bottom of the tube . Sedimentation rate is often abbreviated as sed rate or ESR.
What Is The Normal Range Of Erythrocyte Sedimentation Rate
The ESR medical abbreviation for erythrocyte sedimentation rate depends on various factors like medicines you use, old age, menstrual cycle, and pregnancy. The erythrocyte sedimentation rate is defined as the distance between the plasma and the red blood cells in millimetres observed after 1hour. The ESR blood test normal range as per your age and gender are tabulated below:
| S.No. |
| 0 30 mm/hour |

By taking and testing a small sample of a persons blood, doctors can check for many kinds of diseases and conditions. Blood tests help doctors check how the bodys organs are working and see if medical treatments are helpful.
To help your child get ready for a blood test, find out if they need to fast or should stop taking medicines before the test. Explain what to expect during the test. If your child is anxious about it, work together on ways to stay calm.
Extreme Elevation Of The Esr
An extreme elevation of the ESR is associated with a low false-positive rate for a serious underlying disease.22,23 The conditions found in this situation have varied in individual populations, depending on patient age and inpatient versus outpatient status. In most series, infection has been the leading cause of an extremely elevated value, followed by collagen vascular disease and metastatic malignant tumors.22 Renal disease has also been a notable etiologic factor.3
Because most of these conditions are clinically apparent, any tests performed should be clinically driven. For instance, if symptoms of infection are present, the appropriate cultures, including urine and blood, and skin testing for tuberculosis should be obtained.22,23 An exhaustive search for an occult malignancy should not be undertaken because, if cancer is present, it is almost always metastatic.1,3
No obvious cause is apparent in fewer than 2 percent of patients with a markedly elevated ESR. In such patients, the history and physical examination coupled with readily available tests will usually establish the etiology. Because a notable number of patients with an ESR greater than 100 mm per hour have myeloma or some other type of dysproteinemia, urine and serum protein electrophoretic studies should be included in the testing.3

What Happens If Erythrocyte Sedimentation Rate Is High
Erythrocyte sedimentation rate can be identified as the rate at which red blood cells settle out when anticoagulated is allowed to stand. It is a non-specific indicator of ongoing inflammation and tissue damage. It is affected by the concentrations of immunoglobulins and acute phase proteins like fibrinogen, C-reactive protein, and haptoglobin, which become elevated in ongoing inflammation.
When discussing ESR it is important to know what happens if erythrocyte sedimentation rate is high. ESR test result reference range varies according to age and sex. For men who are < 50 years < 15mm/hour is considered as normal. For women, it is < 20mm/hour. In newborns, the normal reference range is 0-2mm/hour and for children, it is 3-13mm/hour.
It Is Also A Likely Possibility For Your Esr Levels To Be Lower Than Normally Expected Due To Conditions Like:
1. Heart issues / likely failure
2. Kidney and/or liver concerns
3. RBC disorders
5. Sickle cell anaemia
6. Leukocytosis
A point worth noting is that ESR test resultsalone cannot diagnose any disease or medical condition. An ESR test must be used in conjunction with other tests whenever you book a blood test online or at a blood test lab near you, to detect and monitor health problems. An ESR test should also never be self-interpreted like any other test, and rather should be run by a doctor who can aptly explain its significance.

Why Else Could Sedimentation Rate Be Elevated
Overweight and obese people, along with older adults, tend to have naturally higher baseline sedimentation rates, says Dr. Schulz, so a high ESR doesnt necessarily signal a problem in those groups. Someone might have a higher level that is natural to them, he says. It might look abnormal, but its not.
What Abnormal Results Mean
An abnormal ESR may help with a diagnosis, but it does not prove that you have a certain condition. Other tests are almost always needed.
An increased ESR rate may occur in people with:
- Cancers such as lymphoma or multiple myeloma
The immune system helps protect the body against harmful substances. An autoimmune disorder is when the immune system mistakenly attacks and destroys healthy body tissue. ESR is often higher than normal in people with an autoimmune disorder.
Common autoimmune disorders include:
Very high ESR levels occur with less common autoimmune or other disorders, including:
- Allergic vasculitis
An increased ESR rate may be due to some infections, including:
- Bodywide infection
- Infection of the heart or heart valves
- Rheumatic fever
- Severe skin infections, such as erysipelas
- Low plasma protein
- Polycythemia
- Sickle cell anemia

Diagnosing Rheumatoid Arthritis With Blood Tests
Rheumatoid arthritis blood tests are only one way to help doctors reach a diagnosis. If a patient is positive for any of these tests, they must also exhibit specific symptoms of rheumatoid arthritis. Doctors look at multiple other criteria besides blood test results when determining their diagnosis.
In some cases, patients can still be diagnosed with rheumatoid arthritis even if they dont test positive for the various types of antibodies found in rheumatoid arthritis blood tests.
Read more about diagnosing rheumatoid arthritis and the different types of rheumatoid arthritis here.
What Is Sedimentation Rate
Erythrocyte sedimentation rate measures levels of inflammation in the body. When the body is inflamed, it starts producing abnormal proteins that make red blood cells clump together, says Stuart D. Kaplan, MD, chief of rheumatology at South Nassau Communities Hospital in Oceanside, New York.
A doctor will put a blood sample in a tube, then measure how far the red blood cells sink to the bottom in an hour. Theyll drop faster when inflammation makes them form dense clumps, so a high sed rate signals high inflammation.

What Diseases Does The Esr Test Help Diagnose
Sed rate wont guide doctors to a specific diagnosis, but it does reveal whether a patient is likely to have autoimmune problems. I use it as a tool to determine if they have an inflammatory process, says Dr. Schulz. If someone is coming in with joint pain or muscle pain or fatigue, the question Im answering is: Do they have an autoimmune disease, or is it strained?
How Does The Esr Blood Test Work
An ESR test measures the rate at which your red blood cells fall to the bottom of a test tube. The blood sample for this test is measured over the course of an hour.
When youre experiencing inflammation, it can affect your RBCs in a number of ways. First, your RBCs cling together, forming clumps. This clumping affects the rate at which RBCs sink inside a tube where a blood sample is placed.
Also, if you have an acute infection or chronic inflammation, there may be more proteins in your RBCs. This can cause them to settle quicker. The faster and further the cells sink toward the bottom of a test tube, the more likely it is that inflammation is present.
In all, your ESR number is based on the rate that your RBCs settle. The faster this happens, the higher your ESR and the more inflammation is likely in your body.

Esr Blood Test Normal Range
The normal ESR values in mm/hr are listed below and classified as per the age and gender.
- For men above 50 yrs the normal ESR value is below 20
- For men under 50 yrs the normal ESR value is below 15
- For women over 50 yrs the normal ESR value is below 30
- For women below 50 yrs the normal ESR value is below 20
- For newborns the normal ESR value ranges from 0 to 2
- For neonatal till puberty the normal ESR value ranges from 3 to 13
The above ESR values are indicative of the normal range. However, one must be aware of the fact that a number of factors can lead to abnormal ESR values. These factors are explained below
What Is The Normal Range Of Esr In Females
The normal range of erythrocyte sedimentation rate is calculated using the Westergren method, which is considered a gold standard for measuring ESR. In this method, the blood sample is mixed with sodium citrate in a Westergren-Katz tube and is set vertically for one hour at room temperature. After an hour, how far the red blood cells have settled is measured.
On average, the normal reference range for ESR is approximately 1 20 mm/h for females. According to the University of Rochester Medical Centre, the normal range of ESR in females at different age groups when calculated using the Westergren method is
| S.No. |
- Systemic infection
- Heart infection
If the levels of ESR in your test report are greater than 100 mm/h, it may be an indication of any of the following disorders:
- White blood cell cancer
- Plasma cell cancer
- Blood vessel inflammation
- Temporal arteritis

What Are The Causes Of Abnormal Esr Levels
The ESR levels are not indicative of any particular disease, but it only tells about whether or not there is the presence of inflammation in your body. The values for an ESR test are not very strict as the ultimate low levels of ESR can vary in different situations. The abnormal levels of ESR may indicate a mild symptom or a severe disease. So, you must not be concerned a lot about the abnormal values of your ESR test before concerning them with your doctor.
What Do The Sed Rate Blood Test Results Mean
It takes 60 minutes for the sed rate blood test to be completed. The results will be reported in the actual distance that the red blood cells have descended to the bottom of the tube over that 60 minute period. Anything that is below 29mm for women or 22mm for men is considered to be a normal result. Keep in mind that any dropping of the red blood cells indicates inflammation. Even though the results may be normal, there still may be an issue that needs to be addressed.
Anything above these two figures is considered a positive sed rate blood test result. Follow-up testing will be required to pin down the cause of inflammation that exists.
Certain health conditions and lifestyle choices may affect how quickly red blood cells begin to settle. Women who are pregnant may have inconclusive results with this particular test. People who have anemia or high cholesterol may also have results that are inconclusive. Some kidney problems are also known to interfere with the sed rate blood test. A medical provider may be able to take these individual concerns into account to interpret the results.Very high sed rate results occur when people have tumors that make a large amount of immunoglobulin or have multiple myeloma. This happens even if there isnt inflammation present in the body. If results are severely high, then follow-up testing to confirm one of these health issues.
Moderately high levels are often seen because of the normal aging process.

Heres What You Should Know
Some medical providers have a rapid sed rate test that can have test results ready in less than 5 minutes. This may be useful for diagnosis certain conditions in children, such as juvenile rheumatoid arthritis or Kawasaki disease.
Some medications and supplements are also known to interfere with test results. Oral contraceptives, dextran, and some antibiotics may increase sed rate results, while aspirin and cortisone are known to lower test results.
The sed rate blood test is not a specific test, so it isnt suitable for everyone. It is most useful for a known inflammatory condition that needs to be monitored. This means people who are generally healthy will not have any useful information created from the sed rate test results unless there is a severely high result, which is fairly uncommon.
The sed rate blood test has fallen out of favor for some of the health conditions it was previously used to detect thanks to the evolution of blood tests over the years. This doesnt mean the information it can provide isnt beneficial. Specific health concerns benefit from this test, so speak to your medical provider about the pros and cons of the sed rate test to see if it could be right for you.
To measure the sedimentation rate, the blood is placed in a thin, tall tube so that the red blood cells settle to the bottom. Inflammation causes the cells to clump, so higher levels of inflammation cause faster clumping and sedimentation rates.
