ESR Tube Vacuum Blood Collection Tube

ESR Tubes for Accurate Blood Sedimentation Tests ESR tubes are specifically designed for the collection and transportation of venous blood, used in the Westergren method for sedimentation rate tests. These tubes provide precise measurements of the erythrocyte sedimentation rate (ESR), an important diagnostic tool to assess changes in plasma proteins associated with various conditions such as infections, tumors, and degenerative diseases. Manufactured by Greiner Bio-One, these plastic ESR tubes are equipped with a predefined vacuum to ensure accurate blood aspiration volumes. Each tube is filled with a 3.2% trisodium citrate solution, which serves as a buffer to maintain the integrity of the sample. The citrate solution is mixed with blood in a ratio of 1:4, ensuring consistent results. The tubes are sterile, ensuring safe handling and use in clinical environments.
