What is the normal rate of ESR in a blood test?

If you need to know which are the ESR reference rates or you require more information about ESR in a blood test, you can visit normal ESR rate in a blood test

What does a high ESR mean?

The ESR (Erythrocyte Sedimentation Rate) is the rate at which erythrocytes settle out of anticoagulated blood in 1 hour.

A high ESR rate is not specific as a general screening test because it may occur in many diseases. A high ESR rate should be studied along other blood tests to give a clue about the possible diagnosis.

A pathologic reason for an increased ESR rate is usually an inflammation, an infection or a tissue injury. An increased ESR rate is also common is some types of cancer (lymphoma, multiple myeloma) or in autoimmune diseases (lupus, arthritis).

The ESR should not be used to screen asymptomatic patients for disease because many times the reason for a high ESR in not clear.

When there are symptom related it might be useful to diagnose the following diseases:

In pregnant women or in elderly people ESR normal rates are higher than normal.

  • Mild ESR increase (15 - 50 mm/h in adult men and 20 - 50 mm/h in adult women):

    A mild ESR increase is not usually a matter for concern. The most common causes are anemia, inflammation or bacterial infection.

    If you do not have any related symptoms, you should not be worried about it. It is probable that ESR rate will return to normal range in future blood tests.

    Normal ESR rates are higher in people over 50 years old. Rates up to 20mm/h in men and 30 mm/h are considered in the normal range.

  • Moderate ESR increase (50 - 100 mm/h in adults):

    A moderate ESR increase may be due to several reasons such as an infection, an autoimmune disease (arthritis), a kidney disorder or various types of cancer. ESR is not very high, but a visit to your doctor is recommended.

    If you are over 50 years old and suffer pain or stiffness in more than one joint, it may be due to rheumatoid arthritis or polymyalgia rheumatica. Discuss both possibilities with your doctor.

    The ESR may be very high (up to 60 mm/hr) in apparently healthy women aged 70 to 89 years.

  • Severe ESR increase (> 100 mm/h in adults):

    A severe ESR increase is a matter of concern. You should visit your doctor to study the possible causes and get a diagnosis.

    The most common causes are:

    For ESR rates greater than 100 mm (in the nonpregnant client, of course), the most likely causes are in this order infections, malignant tumors, or autoimmune diseases.

    If you are over 50 years old and have headaches and vision problems, it may be due to a disease called temporal arteritis.

Which factors can raise the ESR in a blood test?

There are some health circumstances or drugs than can raise your ESR rate in a blood test:

Which diseases can raise your ESR in a blood test?

The most common diseases why the ESR rate can be higher than normal are:

What can I do to lower the ESR?

The only way to lower the ESR rate is trying to reduce the inflammatory or infectious process that is causing it.

ESR rate is only an indirect parameter and high rates suggest possible underlying diseases, but do not cause any symptoms by itself.

Which values are considered a high ESR rate in a blood test?

The following rates are considered to be above the normal range:

IMPORTANT: These rates are expressed in mm/h (millimeter/hour). They are an example of a healthy man of about 40 years old with no known disease and not taking any medication. The rates can be different depending on the laboratory or on your personal circumstances.
