Erythrocyte Sedimentation Rate (ESR)
Erythrocyte Sedimentation Rate (ESR)
A laboratory test that measures the rate at which red blood cells settle in a tube of blood over one hour.
High ESR
High ESR
A high ESR can indicate inflammation, infection, or autoimmune diseases.
Low ESR
Low ESR
A low ESR can occur in individuals with low levels of inflammation or certain medical conditions.

Study Notes
Importance of Laboratory Conditions
- The tube is placed in an isolated area in the laboratory to minimize vibrations that can affect the accuracy of the ESR measurement.
Sources of Error in Westergren Method
- Vibrations can be a source of error in the Westergren method for measuring ESR.
- Other sources of error include variation in anticoagulant amount and improper tube handling.
Importance of Standard Anticoagulant Amount
- Using a standard amount of anticoagulant is crucial in the ESR test to ensure accurate results, as variations can affect the measurement.
Effect of Polycythemia on ESR
- Polycythemia, a condition characterized by an increased number of RBCs, can decrease the ESR due to the increased RBC aggregation.
Role of Plasma Albumin in RBC Sedimentation
- Plasma albumin helps to inhibit the aggregation of RBCs, which in turn affects the sedimentation rate.
Erythrocyte Sedimentation Rate (ESR)
- ESR is a measure of the rate at which RBCs settle at the bottom of a vertical tube, usually measured in mm/h.
- It is a non-specific indicator of inflammation and can be affected by various factors.
Measurement of ESR
- The Westergren method is commonly used for manual measurement of ESR.
- The Wintrobe Set is also used for the measurement of ESR.
- The Westergren tube is a special tube used in the measurement of ESR, with a precise volume and dimensions.
Purpose of ESR Test
- An ESR test helps detect inflammation, infection, and autoimmune disorders.
