ESR tubes are used to conduct erythrocyte sedimentation rate (ESR) blood test, a type of blood test that measures how quickly red blood cells (erythrocytes) settle at the bottom of a test tube that contains a blood sample. Doctors may order an ESR test if a child has signs of infection or inflammation. They use ESR Tubes to follow conditions such as lupus, arthritis, and inflammatory bowel disease (IBD). ESR tubes and ESR tests can also help doctors see how well treatment for infection or inflammation is working.
The normal ESR range is 0 to 22 mm/hr for men and 0 to 29 mm/hr for women. ESR levels higher than 100 mm/hr could suggest a serious disease, such as cancer, cardiovascular disease, and infection. ESR values of 40 and 60 mm/h clearly indicate a state of heightened systemic inflammation among people who already have an inflammatory disease. An extreme elevation of ESR is strongly associated with serious underlying disease, most often infection, metastatic malignancy, and collagen vascular disease, among others.
The ESR test is used to determine symptoms of an inflammatory disorder such as fever, weight loss, headache, and anemia, among others. ESR tubes are used with ESR analyzers, for clinical and diagnostic purposes. The ESR tubes measure the rate at which red blood cells settle out of plasma. There is an increasing demand for ESR tubes and analyzers in diagnostic laboratories, hospitals, and academic institutions. ESR tubes are made up of glass and plastic materials with anticoagulant additives such as sodium citrate.
Moreover, with the increasing number of blood infections around the world, the demand for ESR tubes and analyzers is also increasing with a rapid pace. For instance, in September 2019, Alcor Scientific announced the launch of the miniiSED, the newest addition to its iSED family of ESR analyzers in the United States. According to the company, miniiSED is fast, accurate, and unaffected by the many variables known to be associated with traditional methodologies.
