Erythrocyte Sedimentation Rate (Sed Rate, ESR)


Normal Range = Male: < 10. Female: < 15.  

A marker of non-specific inflammation, tends to be raised in lupus.

Various inflammatory conditions, including autoimmune conditions, increase the rate at which the red blood cells (erythrocytes) sink in a test tube and form a sediment.

Increased in infections (osteomyelitis, pelvic inflammatory disease [75%]), inflammatory disease (temporal arteritis, polymyalgia rheumatica, rheumatic fever), anemia, pregnancy, chronic renal failure, GI disease (ulcerative colitis, regional ileitis).

Decreased in congestive heart failure, drugs (high dose corticosteroids).

Low value of no diagnostic significance.

ESR is higher in women and older persons.
