Sedimentation Rate (ESR)

The Sed Rate (ESR) test is a simple but effective way to detect inflammation in your body. It measures how quickly red blood cells sink to the bottom of a tall, thin tube. When inflammation is present, certain proteins cause these cells to clump together and sink faster. While it doesn't pinpoint exactly where the problem is, a high "sed rate" acts as a vital warning sign that your body is fighting an infection or dealing with a chronic inflammatory condition.
