Useful For

The erythrocyte sedimentation rate (ESR or sed rate) is a relatively simple, inexpensive,
non-specific test that has been used for many years to help detect
inflammation associated with conditions such as infections,
cancers, and autoimmune diseases.
ESR is said to be a non-specific test
because an elevated result often indicates the presence of
inflammation but does not tell the health practitioner exactly
where the inflammation is in the body or what is causing it. An
ESR can be affected by other conditions
besides inflammation. For this reason, the ESR is typically used in conjunction with other
tests, such as C-reactive protein.
ESR is used to help diagnose certain
specific inflammatory diseases, temporal arteritis, systemic
vasculitis and polymyalgia rheumatica. A significantly elevated
ESR is one of the main test results used
to support the diagnosis.
This test may also be used to monitor disease activity and
response to therapy in both of the above diseases as well as some
others, such as systemic lupus erythematosus (SLE).
