ESR Tube

Determination of the Erythrocyte Sedimentation Rate for fully automated analyzers. ESR 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, to measure inflammation as inflamed red blood cells settle quickly relative to normal blood cells. A high ESR could be indicative of elevated inflammation. ESR tube is one kind of whole blood collection tube.
