Erythrocyte Sedimentation Rate
This is a blood test in which the red blood cells are measured on how long it takes for the cells to settle in a saline or plasma solution over a specified amount of time. In the case of an inflammation or infection in the body, the red blood cells become heavier and will settle more rapidly. This test is used to evaluate and manage rheumatoid arthritis, as well as other inflammatory conditions.
PREPARATION FOR TEST
Some medications may need to be held in the case that they may affect test results. Your caregiver will let you know if this is necessary.
Male: up to 15 mm/hr

The ESR results depend on which test the lab uses.
