Blood Test For Sed Rate

Is Esr 35 High

Erythrocyte Sedimentation Rate (ESR) Made Simple

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 3540 mm/hr in healthy aged persons.

What Is The Erythrocyte Sedimentation Rate

The ESR blood test is an easy, inexpensive, non-specific test that has been used for many years to help diagnose conditions associated with acute and chronic inflammations, including infection, cancer and autoimmune disease. ESR is said to be non-specific because increases do not tell the doctor exactly where the inflammation is in your body or what is causing it therefore it is often used in conjunction with other tests. The ESR test is helpful in diagnosing two specific inflammatory diseases: temporal arteritis and polymyalgia rheumatica, where a high ESR is one of the main test results used to confirm the diagnosis. It is also used to monitor disease activity and response to therapy in both these diseases. A moderately elevated ESR occurs with inflammation, but also with anaemia, infection, pregnancy and advanced age. A rising ESR can mean an increase in inflammation or poor response to a therapy, whereas a decreasing ESR can mean a good therapeutic response .

According to the above, a drop in the ESR level is indicative of a positive response to therapy and the opposite is true when the ESR level is on the increase. Although my study shows a clear picture of reduction in ESR levels , it is by far too small a trial to claim a major result. I therefore urge my TCM colleagues and doctors, in particular, immunologists, to undertake further investigation on this subject.

Monitoring Response To Therapy

The clinical usefulness of ESR is limited to monitoring the response to therapy in certain inflammatory diseases such as temporal arteritis, polymyalgia rheumatica and rheumatoid arthritis. It can also be used as a crude measure of response in Hodgkin’s lymphoma. Additionally, ESR levels are used to define one of the several possible adverse prognostic factors in the staging of Hodgkin’s lymphoma.

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

That depends on the laboratory performing the test. Results may be available the same day or, if the sample is sent to a reference laboratory, it may take a day or two for your results.

Traditional ESR tests are read by a technician one hour after the test is started. Newer methods can be read at 20-30 minutes and there are now commercial rapid tests available that use a centrifugal method and can be read five minutes after setup. This new method is being used more widely to shorten waiting times for patients, particularly in emergency departments.

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?

What You Can Expect

The sed rate is a simple blood test. You don’t need to fast before the test.

A phlebotomist, nurse or medical assistant will use a needle to draw blood from a vein, most likely a vein in your arm. After the test, the site on your arm might be tender for a few hours, but you’ll be able to resume most normal activities.

What Is An Erythrocyte Sedimentation Rate

An erythrocyte sedimentation rate is a type of blood test that measures how quickly erythrocytes settle at the bottom of a test tube that contains a blood sample. Normally, red blood cells settle relatively slowly. A faster-than-normal rate may indicate inflammation in the body. Inflammation is part of your immune response system. It can be a reaction to an infection or injury. Inflammation may also be a sign of a chronic disease, an immune disorder, or other medical condition.

Erythrocyte Sedimentation Rate (ESR) What Does This Lab Test Really Mean?

A number of conditions can affect the properties of blood, thereby affecting how quickly red blood cells sink in a sample of blood. So information about inflammatory disease what your doctor intends to learn from the sed rate test can be obscured by the influence of other conditions. These complicating factors include:

What is sed rate?

Sed rate is a short form for Erythrocyte sedimentation rate and abbreviated to ESR Test too. Erythrocyte is the scientific name for the red blood cell, sedimentation means the process of depositing sediment, rate means the speed at which the test proceeds which is often expressed in terms of the millimeters of blood that is sedimented in an hour of time.

Sedimentation rate blood test is measured in the medical laboratory by letting an amount of blood to separated and settled to the bottom of a tube in a certain amount of time so that the RBC sed rate is the volume of Red blood Cells precipitated in an hour time.

Sed rate test is the most used marker for chronic inflammations.

What is sed rate used for?

Why does my doctor want me to take ESR blood test?

The main purpose to measure the rate of RBC sedimentation is to monitor the inflammation progress, inflammation means normally increased body defense due to the existence of an injury or casual agents such as trauma, post-surgery, infection by bacteria or worms, and allergic reaction in response to immunological reasons as in Systemic Lupus Erythematosus and Rheumatoid Fever or Non-immunological causes such as the acquired allergies by drugs.

The Inflammatory response triggers the bodys proteins and cells in the so-called Exudate, RBC becomes heavy and ill due to high weight blood content.

  • To state the progression of a disease
  • 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 An Esr Test

    The erythrocyte sedimentation rate is a blood test performed to measure the rate at which the red blood cells settle at the bottom of the test tube containing the blood sample. This test is generally done to diagnose any condition that might lead to inflammation. The rate at which red blood cells settle down gives your doctor an idea about any inflammation or acute infection in your body.

    What Do The Results Mean

    If your ESR is high, it may be related to an inflammatory condition, such as:

    Sometimes the ESR can be slower than normal. A slow ESR may indicate a blood disorder, such as:

    If your results are not in the normal range, it doesn’t necessarily mean you have a medical condition that requires treatment. A moderate ESR may indicate pregnancy, menstruation, or anemia, rather than an inflammatory disease. Certain medicines and supplements can also affect your results. These include oral contraceptives, aspirin, cortisone, and vitamin A. Be sure to tell your health care provider about any drugs or supplements you are taking.

    How Is A Sedimentation Rate Test Performed

    A sedimentation rate is performed by measuring how long it takes red blood cells to settle in a test tube. The RBCs become sediment in the bottom of the test tube over time, leaving the blood serum visible above.

    • The classic sedimentation rate test is typically performed in a calibrated narrow tube.
    • The sedimentation rate is measured simply by recording how far the top of the RBC layer has fallen from the top of the serum layer in one hour.
    • The sedimentation rate increases when more inflammation is present in the body of the person whose blood was sampled because inflammation alters certain substances on the surfaces of the red blood cells, making them tend to adhere together and more rapidly fall to the bottom of the test tube.

    Screening For Systemic Disease Or Neoplasia

    Erythrocyte Sedimentation Rate explained

    Unfortunately, the ESR is neither sensitive nor specific when used as a general screening test.1,3,19 For instance, the ESR may be elevated in the presence of infectious disease, other inflammatory or destructive processes, collagen vascular disease or malignancy,13 but it may not be increased in a number of infectious diseases , allergic processes, angina or peptic ulcer disease .

    Because an elevated ESR may occur in so many different clinical settings, this finding is meaningless as an isolated laboratory value. In addition, some patients who have malignant tumors, infections or other inflammatory disorders will have normal ESR values. Most unexplained ESR elevations are short-lived and not associated with any specific underlying process. In those instances where disease is present, it will usually be obvious after completion of history taking, physical examination and collection of routine laboratory data.3

    The rheumatoid arthritis blood tests that doctors perform to help diagnose the disease include:

    • Rheumatoid factor
    • C-Reactive Protein
    • Antinuclear Antibody

    None of these tests can singularly conclude that a patient has rheumatoid arthritis. Rather, doctors look at the combined results from all, alongside a number of other criteria including physical symptoms and genetics, in order to reach a rheumatoid arthritis diagnosis.

    Erythrocyte Sedimentation Rate Blood Test

    Erythrocyte sedimentation rate test or sed rate test, is a blood test that checks for inflammation. It measures the distance in millimeters that red blood cells fall in one hour .

    There are a few ways that this is measured, such as the Westergren method, Wintrobe Method, MicroESR, and automated methods .

    Screening For Infection In Specific Clinical Settings

    Recent studies have evaluated the ESR as a screening test for infection in specific clinical instances such as infection associated with orthopedic prostheses, pediatric bacterial infection and gynecologic inflammatory disease.6,7,20 Although frequently abnormal in patients who have an infected prosthesis, the ESR value is not as sensitive or specific an indicator of infection as joint aspiration.20 Elevation of the ESR has been proposed as a clue to the presence of an invasive bacterial infection in children after the first 48 hours of symptoms.6 In one investigation,7 the ESR more accurately indicated the severity of acute pelvic inflammatory disease than did the physical examination, thus helping to evaluate patients who required antimicrobial therapy. The appropriateness of the ESR as a screening test for infection, even in these well-defined clinical settings, requires further evaluation.

    How Is The Test Used

    The erythrocyte sedimentation rate is a relatively simple, inexpensive, non-specific test that has been used for many years to help detect inflammation associated with conditions such as infections, cancers, and autoimmune diseases.

    ESR is said to be a non-specific test because an elevated result often indicates the presence of inflammation but does not tell the health practitioner exactly where the inflammation is in the body or what is causing it. An ESR can be affected by other conditions besides inflammation. For this reason, the ESR is typically used in conjunction with other tests, such as C-reactive protein.

    ESR is used to help diagnose certain specific inflammatory diseases, including temporal arteritis, systemic vasculitis and polymyalgia rheumatica. A significantly elevated ESR is one of the main test results used to support the diagnosis.

    This test may also be used to monitor disease activity and response to therapy in both of the above diseases as well as some others, such as lupus.

    What Does The Test Result Mean

    The result of an ESR is reported as the millimeters of clear fluid that are present at the top portion of the tube after one hour .

    Since ESR is a non-specific marker of inflammation and is affected by other factors, the results must be used along with other clinical findings, the individual’s health history, and results from other laboratory tests. If the ESR and clinical findings match, the health practitioner may be able to confirm or rule out a suspected diagnosis.

    A single elevated ESR, without any symptoms of a specific disease, will usually not give enough information to make a medical decision. Furthermore, a normal result does not rule out inflammation or disease.

    Moderately elevated ESR occurs with inflammation but also with anemia, infection, pregnancy, and with aging.

    A very high ESR usually has an obvious cause, such as a severe infection, marked by an increase in globulins, polymyalgia rheumatica or temporal arteritis. A health practitioner will typically use other follow-up tests, such as blood cultures, depending on the person’s symptoms. People with multiple myeloma or Waldenstrom’s macroglobulinemia typically have very high ESRs even if they don’t have inflammation.

    When monitoring a condition over time, rising ESRs may indicate increasing inflammation or a poor response to a therapy normal or decreasing ESRs may indicate an appropriate response to treatment.

    What Are The Reasons For Performing A Sedimentation Rate Test

    Doctors use the sedimentation rate to help to determine if inflammation is present in the patient. Additionally, the sedimentation rate can be a convenient method of monitoring the progress of treatment of diseases that are characterized by inflammation. Accordingly, a high or elevated sedimentation rate would correlate with more disease activity while a low sedimentation rate would suggest that the disease is less active.

    Examples of diseases that are commonly monitored with the sedimentation rate test include

    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.
