No need to worry when your doctor wants you to take a sedimentary erythrocyte rate or ESR test. It's a routine exercise that is simple and quick. The test itself doesn't diagnose a specific condition. Instead, it's a test that could help the doctor verify whether there's some inflammation occurring in any part of your body. Together with some related information or other criteria, it can lead to an accurate diagnosis. The type of ESR test will depend upon the symptoms. But one thing that the test can monitor is the presence of inflammatory diseases.

The test will involve a tall and thin tube that contains your blood sample. When standing alone, the doctor will measure the rate at which the RBCs fall to the tube's bottom. If there is inflammation, abnormal proteins will show up in the blood. This abnormality will cause the RBCs to form clumps, causing them settle to the bottom faster.

What is the purpose of ESR test?

Doctors will usually prescribe the ESR test to find out if there's inflammation in the body. The results, in conjunction with other tests, can help the doctor make a diagnosis of what is causing the inflammation. Usual diseases involved are cancers, infections, and autoimmune diseases.

The test can also help in monitoring inflammatory disorders. If you have symptoms like specific muscle problems, some arthritis or fever, your doctor may require an ESR test.

How does the doctor use the test?

The ESR Test is a relatively inexpensive and straightforward test which medical professionals frequently depend on. It's a non-specific test, but its results can be beneficial for other types of tests to come up with a medical diagnosis. The test can determine the presence of inflammations associated with various diseases. The ESR test will indicate the presence of swelling. But it won't specify the location of the inflammation. Other body conditions besides inflammations can easily influence the ESR test.

To be sure that the diagnosis will cover all angles of the patient's symptoms, doctors use the ESR test alongside other tests. A result that's significantly-elevated will support the doctor's diagnosis of the patient's disease. As mentioned earlier, the ESR is also essential in monitoring disease activities and the response to treatment of said diseases.

How does the procedure of the test go?

The procedure for the ESR test is simple and involves very minimal risk. A medical professional will draw some blood from the patient's vein. First, they sanitize the skin, then tie an elastic band to get the vein to swell. A needle is then inserted into the vein, and then a blood sample will be drawn. Lastly, they remove the elastic band and pull the needle out.

In the case of babies, pros would collect blood differently in a method called the "heel stick collection." First, they clean the area; then they will prick the heel of the baby with a needle to collect enough blood sample for the test. The procedure won't cause much pain for the baby, just temporary discomfort.
