Erythrocyte sedimentation rate is the test in which anticoagulant is added to a venous blood sample.
What does a high erythrocyte sedimentation rate mean?
- A blood test called an erythrocyte sedimentation rate (ESR) can determine whether you have inflammation in your body.
- Your immune system responds to injury, infection, and many illnesses, such as immune system disorders, some malignancies, and blood problems, by inducing inflammation.
- Red blood cells are called erythrocytes.
- A sample of your blood is sent to a facility for an ESR test.
- The sample is put in a tall, thin test tube by a medical practitioner, who then gauges how quickly the red blood cells settle or sink to the bottom of the tube.
- Red blood cells typically sink gradually. However, red blood cells clump together as a result of inflammation.
- Since these cell clusters are heavier than individual cells, they sink more quickly.
