ESR Normal Range

What is the ESR Normal Range? Erythrocyte sedimentation rate (ESR) is a blood test. ESR above 100 mm/h is most likely caused by active disease or infections. It measures how quickly erythrocytes, or red blood cells, separate from a blood sample that has been treated so the blood will not clot. During this test, a small amount of your blood will be put in an upright tube. A lab technician will measure the rate that your red blood cells settle toward the bottom of the tube after 1 hour.

If you have a condition that causes inflammation or cell damage, your red blood cells clump together. This makes them heavier, so they settle faster. The faster your red blood cells settle and fall, the higher your ESR. A high ESR tells your doctor that you may have an active disease process or any kind of inflammation in your body.

Table of ESR Normal Range

ESR test results may vary depending on your age, gender, health history, the method used for the test, and other things. Many times, your test results may not mean you have a problem. Ask your doctor what your test results mean for you, as the doctor is the right person to diagnose it by comparing your health records. 

ESR is measured in millimetres per hour (mm/h). The normal values are:

  • 0 to 10 mm/h in children
  • 0 to 15 mm/h in men younger than 50
  • 0 to 20 mm/h in men older than 50
  • 0 to 20 mm/h in women younger than 50
  • 0 to 30 mm/h in women older than 50

ESR above 100 mm/h is most likely caused by active disease or infections. For instance, you may have;

  • A disease that causes inflammation in your body
  • Active infection
  • Cancer
  • Heart disease
  • Kidney disease
  • Blood disease
  • Diabetes
  • Collagen vascular disease

ESR Test Results Meaning

Many things that are not active diseases or infections can increase your ESR test result. Some of these include;

  • Pregnancy
  • Old age
  • Being female
  • Having a menstrual period
  • Having recently eaten a fatty meal
  • Being obese
  • Taking certain medicines

What other Tests I Should do If my ESR Test Result High?

ESR Test Results High? You may have to do other tests if your doctor is doing this test to diagnose a disease. One of these tests is C-reactive protein or CRP. This test also measures active inflammation in the body. Your lab technician may do an ESR alone if he or she is monitoring a disease you already have. Because ESR tells your doctor only what is happening right now, you may need to have the test repeated.

Why ESR Test is Done?

You may need the esr test if you have symptoms of one disease that may cause ESR to go up. Why esr test is done?

  • You may also need this test if you have already been diagnosed with a disease that causes a high ESR.
  • The test can allow your doctor to see how well you are responding to treatment.
  • The ESR blood test is most useful for diagnosing or monitoring diseases that cause pain and swelling from inflammation.
  • Other symptoms may include fever and weight loss.

Your doctor needs to monitor your esr test result if you have diagnosed with few diseases, these include;

  • Temporal arteritis
  • Rheumatoid arthritis
  • Polymyalgia rheumatica

ESR is not used as a screening test in people who do not have symptoms or to diagnose disease because many conditions can cause it to increase. It might also go up in many normal cases. ESR doesn’t tell your doctor whether you have a specific disease. It only suggests that you may have an active disease process in your body.

ESR Test Preparation

You don’t need to prepare for this test. Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don’t need a prescription and any illicit drugs you may use. Tell your provider if you ate a fatty meal recently, if you are having your period, or if you may be pregnant.
