>> FAQ
Q1. What is an Erythrocyte Sedimentation Rate (ESR)?
A: A blood test called an erythrocyte sedimentation rate (ESR) gauges how rapidly red blood cells, or erythrocytes, settle to the bottom of a test tube containing a blood sample. Red blood cells often settle fairly slowly. A higher-than-average rate could be a sign of internal inflammation. Inflammation is a normal aspect of your immune system's response. It could be a response to an injury or infection.
Q2: What is the Method of ESR Test?
A: 1.ESR can be measured using a variety of methods, including the Westergren, Wintrobe, and micro-ESR methods, as well as automated devices. The Westergren method is the most often used ESR method.
2. The Westergren method has traditionally been used to calculate ESR by measuring the distance that RBCs settle to the bottom of a 2.5 cm internal bore elongated tube.
3. The Wintrobe method employs 100-mm-long tubes with a smaller bore (thinner tube) than typical Westergren tubes. It is thought to be less sensitive than the Westergren.
4. The micro ESR is a method of obtaining the ESR that uses capillary tubes and allows for faster testing periods.
