What is wintrobe test?

The Wintrobe test, also known as the Wintrobe sedimentation rate (ESR) test, measures the rate at which red blood cells settle in a vertical tube over a specified period, typically one hour. It is used to assess inflammation in the body, as elevated sedimentation rates can indicate various conditions, including infections, autoimmune diseases, and malignancies. The test is simple and cost-effective, making it a common tool in clinical practice. However, it is a non-specific test and should be interpreted alongside other clinical findings and tests.
