The ESR test, or ESR blood test, measures inflammation by measuring how quickly red blood cells settle in a tube. Low levels can be found in conditions such as polycythaemia or sickle cell anaemia, whereas elevated levels may indicate infections, autoimmune diseases, or cancers.
The immune system can be triggered in reaction to injury, infection, or autoimmune diseases, among other causes, leading to inflammation in the body. It is important to keep an eye on the inflammation levels because it might indicate many underlying medical conditions, such as cancer and arthritis. This simple blood test provides vital data that aids in the decision-making process while treating these conditions. Read on to learn more about the ESR test price and its significance in measuring inflammation levels.
What is an ESR Test?
The rate at which red blood cells (RBCs) settle to the bottom of a test tube is measured by an Erythrocyte Sedimentation Rate (ESR) test, also known as the “sed rate” test. RBC sedimentation is usually normal; however, due to an abnormal immune response, it increases. Deviation from the ESR normal range indicates conditions such as immune disorders, inflammation, injury, infection, or other chronic disorders. Hence, ESR tests are essential for diagnosing and monitoring these conditions, ensuring effective treatment. TheESR test pricevaries based on the diagnostic lab you visit. At Apollo 24|7, the ESR blood test price is just ₹970.
When to Get an ESR Test?
Your healthcare provider may suggest an ESR if you experience symptoms that are indicative of inflammation, which can vary depending on the underlying condition. These symptoms may include:
- Headaches
- Unexplained fever
- Weight loss
- Joint stiffness
- Neck or shoulder pain
- Loss of appetite
- Symptoms of anaemia, such as body pain
- Shortness of breath
- Swelling in a joint
- Weakness
Procedure and Considerations for the ESR Blood Test
Using a tiny needle, a medical expert will collect blood from a vein in your arm and transfer it into a test tube or vial. Usually, this takes under five minutes. No specific preparations are required for this test; however, your provider will inform you if there are any specific instructions to follow. The point where the needle is injected can cause some pain, but generally, there is nothing to worry about.
Interpreting ESR Test Results
It’s not always the case that high or low ESR readings indicate a disease that requires medical attention. Results from an ESR test can be affected by pregnancy, menstrual cycle, ageing, obesity, frequent alcohol consumption, and exercise. Inform your provider about any medications or supplements you take, as they can also have an impact on your blood test results.
RBC sedimentation rate, or the speed at which red blood cells (RBCs) settle in a vertical blood tube, is measured in millimetres per hour (mm/h).
Normal Range
- 0 to 15 mm/hr in men
- 0 to 20 mm/hr in women
A High Range may Indicate
An inflammatory condition could be the cause of a high ESR test result, such as:
- Arteritis
- Systemic vasculitis
- Polymyalgia rheumatica
- Inflammatory bowel disease
- Kidney disease
- Infection
- Rheumatoid arthritis and other autoimmune diseases
- Heart disease
- Certain cancers
A Low Range may Indicate
A low ESR test result indicates a slower-than-normal sinking rate of red blood cells. This could be caused by conditions like:
- A blood disorder like polycythaemia, sickle cell disease (SCD), high white blood cell count (WBC) or leukocytosis.
- Heart failure
- Certain liver and kidney issues
Overall, the ESR test serves as a crucial tool in assessing inflammatory conditions within the body. By measuring the rate of red blood cell sedimentation, it aids in diagnosing various disorders, including arthritis and autoimmune diseases. Notably, the affordability of the ESR test priceoffers peace of mind to patients seeking early detection and management of inflammatory conditions. Its accessibility and diagnosis ensure prompt intervention and improved outcomes for individuals dealing with inflammation-related ailments.
