Erythrocyte sedimentation rate (ESR)

Lab Code : ESR

Test Background
The ESR is a measurement of the rate of fall of red blood cells. The rate at which red cells fall, or sediment, is influenced by the extent to which they form rouleaux – red blood cells clumped together in distinctive ‘stacks’ like coins. Rouleaux formation of red cells means that the red cells fall at a greater rate than individual red cells. The formation of rouleaux is accelerated by the presence of acute phase proteins, which can occur in a wide variety of infective and inflammatory conditions.
