Lupus: Support and Survival -

Erythrocyte sedimentation rate: This blood test determines the rate at which red blood cells settle to the bottom of a tube. A faster-than-normal rate may indicate a systemic disease such as lupus. The sedimentation rate is not specific for one disease but may be elevated in lupus, other inflammatory conditions or with infection.

Erythrocyte Sedimentation Rate - an overview ...

The erythrocyte sedimentation rate is a nonspecific test, and other diseases that may manifest clinically in a manner similar to that of temporal arteritis, such as malignancy or infection, also may markedly elevate the erythrocyte sedimentation rate. Confirmation of the clinical diagnosis of temporal arteritis requires a temporal artery biopsy.

What Are the Symptoms of a High Blood Sedimentation Rate?

The erythrocyte sedimentation rate (ESR) is a commonly performed test but is very nonspecific, which means that having a high ESR does not necessarily tell your physician what is wrong, only that something may be wrong. The ESR is a marker of inflammation, so it can be high with infections and also other types of inflammation.

ESR Count In Blood Test: What Does Low & High ESR Levels Mean?

The erythrocyte sedimentation rate frequently remains high after the subsidence of all clinical symptoms of the disease. This means the disease process is still active at the subclinical level, for example as in case of rheumatic disease. Low ESR is observed in certain conditions where the normal sedimentation rate of blood is suppressed.

ESR: MedlinePlus Medical Encyclopedia

ESR stands for erythrocyte sedimentation rate. It is commonly called a "sed rate." It is a test that indirectly measures how much inflammation is in the body.

Erythrocyte sedimentation rate - Wikipedia

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.

Understanding Lupus Lab Tests and Results | Rheumatology

Erythrocyte Sedimentation Rate (ESR) ESR is an indirect indicator of inflammation. A high ESR, if there are no other reasons for it to be high, such as infection, suggests that lupus is active; a low test is reassuring. The test is simple and cheap but non-specific and subject to inaccuracy.

Erythrocyte | definition of erythrocyte by Medical dictionary

erythrocyte sedimentation rate the rate at which erythrocytes settle out of unclotted blood in one hour. The test is based on the fact that inflammatory processes cause an alteration in blood proteins, resulting in aggregation of the red cells, which makes them heavier and more likely to fall rapidly when placed in a special vertical test tube.
