What is ESR?
ESR, also known as “Erythrocyte sedimentation rate” is a blood test that measures how quickly erythrocytes (red blood cells) settle to the bottom of a test tube in one hour. The test measures the rate at which red blood cells fall or sediment to the bottom of the test tube. A higher-than-normal ESR rate indicates the presence of inflammation in the body.
How is ESR measured?
ESR is measured using a sample of the patient’s blood. The blood is drawn from the patient’s arm and collected into a test tube. The test tube is then placed in an upright position, allowing the blood to settle. After one hour, the height of the clear liquid (plasma) on top of the red blood cells is measured and recorded in millimeters.
ESR reference ranges
The normal ESR ranges for men and women differ. For men, a normal ESR level is less than 15 mm/hr, and for women, a normal ESR level is less than 20 mm/hr. However, the normal range may vary slightly from one laboratory to another.
What causes a high ESR?
A high ESR rate is a sign of inflammation or infection in the body. The following conditions may cause a high ESR:
- Autoimmune diseases such as lupus
- Inflammatory bowel disease
- Kidney disease
What causes a low ESR?
A low ESR is generally not a cause for concern, and it usually indicates that there is no inflammation or infection in the body. However, in some cases, a low ESR may be indicative of sickle cell anemia, polycythemia, or hypofibrinogenemia.
Is ESR a reliable diagnostic tool?
ESR is not a specific test, and a high ESR does not indicate a specific disease or condition. It is used in conjunction with other diagnostic tests to diagnose a condition. A high ESR rate is usually an indication of inflammation or infection in the body.
When is ESR used in diagnosing diseases?
ESR is commonly used to diagnose the following conditions:
- Autoimmune diseases
- Inflammatory bowel disease
- Polymyalgia rheumatica
ESR vs. CRP: What’s the difference?
ESR and C-reactive protein (CRP) are two blood tests used to detect inflammation in the body. While ESR measures the rate at which red blood cells fall or sediment in a test tube, CRP measures the amount of CRP in the blood. CRP levels can increase rapidly in response to inflammation or infection, whereas ESR levels take longer to rise and fall.
Advantages and disadvantages of ESR
ESR is a simple and inexpensive test that can provide useful information about the presence of inflammation or infection in the body. However, ESR is not a specific test and cannot diagnose a specific disease. It is also affected by several factors such as age, gender, and pregnancy, which can make the interpretation of results challenging.
Precautions to be taken during ESR testing
There are a few precautions that need to be taken before undergoing ESR testing. These include:
- Fasting for at least four hours before the test.
- Avoiding strenuous exercise before the test.
- Informing the healthcare provider about any medications or supplements being taken, as they may interfere with the test results.
ESR is a blood test used to detect inflammation or infection in the body. A high ESR rate is an indication of the presence of inflammation or infection, while a low ESR rate indicates the absence of inflammation or infection. ESR is a simple and inexpensive test that can provide useful information about the patient’s health. However, it is not a specific test and should be used in conjunction with other diagnostic tests to diagnose a specific disease or condition.
