Erythrocyte Sedimentation Rate

Erythrocyte sedimentation rate (ESR) is a laboratory test that is used to assess the rate at which red blood cells settle in a test tube under the influence of gravity. This test is an important indicator in the diagnosis of various diseases and conditions, such as infections, inflammatory processes, autoimmune diseases, etc.

ESR is measured in millimeters per hour (mm/h) and can be increased if there is inflammation in the body. An increase in ESR can be caused by various factors, including infections, autoimmune processes, trauma, tumors, etc.

To perform an ESR test, a blood sample is placed in a special tube that contains an anticoagulant that prevents blood clotting. The tube is then rotated for a certain time, after which the height of the blood column in the tube is measured. The higher this column, the higher the erythrocyte sedimentation rate.

The results of the ESR test can be used to diagnose various diseases, evaluate the effectiveness of treatment and monitor health status. However, test results are not the sole criterion for diagnosis and must be interpreted in the context of other clinical findings and symptoms.
