ESR Test - What Does It Show?
ESR (Erythrocyte Sedimentation Rate) is a laboratory test that measures how quickly a blood sample settles.
How Does It Work?
A blood sample is placed in a vertical tube and we measure how long it takes for red blood cells to sink to the bottom in 1 hour. If red blood cells settle faster than usual, this may indicate inflammation.
