The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation .
Studies have shown that elevated levels may predict mortality independent of bone metabolism factors and liver function tests in CKD. Elevated levels are also associated with diabetes, hypertension, and cardiovascular disease; it was found that elevated levels are associated with elevated serum C-reactive protein (CRP), which could reflect an ...
C-reactive protein (CRP) is an annular (ring-shaped) pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells .
In contrast, C-reactive protein (with a half-life of 6–8 hours) rises rapidly and can quickly return to within the normal range if treatment is employed. For example, in active systemic lupus erythematosus, one may find a raised ESR but normal C-reactive protein. [citation needed] They may also indicate liver failure. [11]
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
The faster the red blood cells settle, the higher the ESR value (measured in mm/hour), which suggests that inflammation may be present. Many conditions can cause an elevated ESR, so this test alone is not proof that a person has polymyalgia rheumatica. [17] [18] Another test that checks the level of C-reactive protein (CRP) in the blood may ...
When vasculitis is not active, normal erythrocyte sedimentation rate or C-reactive protein level can occur and should not rule out the diagnosis. When paired with congruent clinical features, an elevated erythrocyte sedimentation rate in giant cell arteritis patients can both support the diagnosis and aid in disease monitoring. [23]
Erythrocyte sedimentation rate, [22] an inflammatory marker, >60 mm/hour (normal 1–40 mm/hour) C-reactive protein, another inflammatory marker, may be elevated [22] LFTs, liver function tests, are abnormal particularly raised ALP- alkaline phosphatase; Platelets may also be elevated
