The erythrocyte sedimentation rate, also known as the ESR or sed rate, is a clinical lab test that measures the rate at which red blood cells in whole blood descend into a standardized tube, reported as mm per hour. This test is used to measure inflammation as inflamed red blood cells settle quickly relative to normal blood cells. Thus, a high ESR can be indicative of elevated inflammation, though other conditions such as anemia, renal failure, and obesity can increase the ESR rate as well. CLS021 is an automated sed rate instrument that provides accurate ESR results in few minutes. It has an excellent correlation with the standard Westergren method. This clinical machine’s test principle is based on the Westergren Method.

ESR (Erythrocyte sedimentation rate) analyzers used in medical laboratories to perform human blood sample analysis. Results analyzed using the Westergren method measures cells descended in millimeters. More precise results are obtained which do not interfere with jaundice, hemolysis, or chyle. It can indicate a disease condition, such as a disease that causes inflammation, active infection, cancer, heart disease, kidney disease, blood disease, diabetes, and collagen vascular disease. Its instrument uses infrared detection technology or other photoelectric technology to periodically scan the position of the red blood cell and plasma interface according to the change of plasma turbidity during the red blood cell sinking process, and dynamically records the whole process of blood sedimentation. The data is processed by the computer to obtain the test result.
