The ESR System test is a common laboratory test used to indicate patient conditions such as acute tissue damage, chronic infection and chronic inflammation. The ESR test measures the rate that erythrocytes settle in human plasma over a specified time period. ESR results are reported in millimeters that the plasma-erythrocyte interface falls in a designated perpendicular Tube of anticoagulated whole blood per hour. ESR results become elevated due to the formation of erythrocyte rouleaux, which is caused mainly by alterations in plasma and erythrocyte factors.There may be situations where the sample cannot be analyzed immediately after it is drawn and must be transported or preserved for future analysis. ESR-Vacuum Tubes preserve the integrity of the patient sample for sed rate analysis until processing and testing can be performed. Samples can be maintained from the time of blood collection for up to 72 hours prior to analysis when transported and/or stored at 2-10° C.ESR Plain Tube Labeling Sleeves are compatible with all configurations of Streck ESR-Vacuum Tubes, and are designed specifically for use with the ESR-Auto Plus analyzer and ESR-10 Manual Rack.
Notes
1. For In Vitro Diagnostic Use.
2. All patient blood samples should be treated as if they are capable of transmitting infections and should be handled with appropriate precautions. Avoid contact with skin and mucous membranes.
3. Used tubes and labeling sleeves containing blood should not be disposed of in general waste, but should be disposed with infectious medical waste.
4. The product is intended for use as supplied. Adulteration by dilution or addition of any materials to the product as supplied, prior to direct draw or transfer procedures, invalidates the intended use of the product.
