ESR test has been automatically performed. When an inflammatory process is rheumatoid arthritis erythrocyte sedimentation rate, the high proportion of fibrinogen in the blood causes red blood cells to stick to each other. Rouleaux formation can, however, be a normal physiological finding in horses, cats, and pigs.
The basal ESR is slightly higher in females. The clinical usefulness of ESR is limited to monitoring the response to therapy in certain inflammatory diseases such as temporal arteritis, polymyalgia rheumatica and rheumatoid arthritis. Additionally, ESR levels are used to define one of the several possible adverse prognostic factors in the staging of Hodgkin’s lymphoma. In 1967 it was confirmed that ESR values tend to rise with age and to be generally higher in women. This formula is no longer credited. Since C-reactive protein levels in the blood rise more quickly after the inflammatory or infective process begins, ESR is often replaced with C-reactive protein measurement.
Several studies investigated the differential diagnostic values of ESR and CRP in inflammatory disease, and concluded ESR is a potential meaningful biomarker for disease differentiation.
