About ESR
ESR, or erythrocyte sedimentation rate, is a simple, non-specific test that rises whenever there is inflammation in your body, whether from infection, autoimmune disease, or other conditions. It is often used alongside CRP to track inflammation over time.
No fasting is required, and results are available the same day.
How to Prepare
- No fasting required.
- No special preparation needed before your blood draw.
Frequently Asked Questions
What does an ESR test measure?
It measures how quickly red blood cells settle in a tube, which rises with inflammation anywhere in the body.
Do I need to fast before this test?
No fasting is required.
Is ESR specific to one condition?
No, it is a non-specific marker, meaning it rises with many types of inflammation, so it is interpreted alongside your symptoms and other tests.
Is ESR tested with CRP?
Often yes, since both track inflammation and together give a fuller picture of trends over time.
How soon will my report be ready?
Same day.
Is home sample collection available?
Yes, in all City Care Lab service areas.
