When I was first diagnosed with Rheumatoid Arthritis (RA) the doctors started talking to me like I knew what all these terms and tests meant. Even after getting an explanation from the doctors, I was so overwhelmed with information that my head was swimming with facts and figures. After I had time to try absorb what they were saying, I realized I needed more information. I wanted to know more than what the test was for, but I wanted to know how it related to my particular heath.

SED rate was one of those terms that doctors talked about. The ESR (Erythrocyte Sedimentation Rate) also know as SED rate is a blood test that measures the how quickly your red blood cells settle to the bottom of a test tube in an hour. The more Erythrocytes (red blood cells) that fall to the bottom, the higher the SED rate.

The test is used to detect signs of inflammation not the cause of inflammation. A normal SED rate is between 15 and 20 millimeters per hour. An elevated SED rate may have many possible causes so it’s important to discuss with your doctor all the potential reasons your SED rate is high.

    Hey Jo-Ann Thanks for the post not just for educating us about SED rate but helping those like myself that don’t ask a lot of questions about a lot of the test and terms that are used but just putting 100% faith in what our doctor tells us! Thanks again
