An Erythrocyte Sedimentation Rate (ESR) blood test (also known as Westergreen Sedimentation Rate) is an important medical screening performed to detect inflammation in the body caused due to many reasons like infection, autoimmune diseases like lupus, rheumatoid arthritis and the Kawasaki disease and also certain types of cancers. This test gives a measurement of the speed at which the red blood cells fall to the bottom of an erect glass tube. Abnormal proteins that may be present in the blood due to various reasons can cause the red blood cells to cluster together and sink down rather quickly. While it is important to know what ESR blood test is, it is also crucial to understand that this test alone is not sufficient to diagnose and conclude a disease.
The ESR blood test needs no specific preparation and requires a technician to draw the blood sample from a vein of the patient and collect the same in a syringe or vial. The whole procedure takes a few minutes and the test results can be made available the ensuing day. If the results show inflammation, the patient’s health professional may ask him/her to undergo further tests to conclude the specific cause for inflammation.
