Erythrocyte Sedimentation Rate (ESR)

🩸 Erythrocyte Sedimentation Rate (ESR) test this test measures the speed of red blood cell sedimentation in the test tube over a specific time. If it sediments faster than normal, this may indicate the presence of inflammation or infection in the body. The test does not determine the exact type of disease, but it gives the doctor a signal that there is an inflammatory or immune problem that requires additional tests. 🩺 Why does the doctor request the test? If there is chronic pain or swelling, or suspicion of infections or autoimmune diseases, or to follow up on the improvement of the condition after treatment. 💡 Advice: No fasting is needed, but it is better to do it in the same lab if you repeat it, so the results are accurate and comparable.
