Wintrobe Tube

The Wintrobe Tube is a laboratory glass tube used primarily for measuring the Erythrocyte Sedimentation Rate (ESR) , which is a test that helps detect inflammation in the body. Key Features: Made of glass, typically about 100 mm in length and 3 mm in diameter. Marked with graduations to measure the sedimentation of red blood cells over time, usually over an hour. Used to assess conditions such as infections, autoimmune diseases, and inflammatory disorders . Works by allowing red blood cells to settle under gravity, and the rate of settling is measured. Usage: Blood is drawn into the tube and anticoagulated (usually with EDTA or citrate). The tube is placed vertically, and the distance the red cells fall in one hour is recorded as the ESR. Significance: The ESR value is an indirect measure of inflammation and can aid in diagnosis and monitoring of disease activity. Chats are processed by Learneo and its service providers.
