Sed rate tests were used more frequently in the past than they are today because more-specific measures of inflammatory activity are now available. Today, the test is most often used if your doctor suspects you have:
- Giant cell arteritis
- Polymyalgia rheumatica
- Rheumatoid arthritis
A sed rate test can also help determine the severity of your inflammatory response and monitor the effect of treatment.
Because a sed rate test can't pinpoint the problem that's causing inflammation in your body, it's usually accompanied by other blood tests, such as the C-reactive protein (CRP) test.
