What This Value Measures
The erythrocyte sedimentation rate measures how quickly red blood cells settle in a test tube. It is a non-specific marker of inflammation.
Elevated Value
An elevated value may indicate inflammation, infections, or other conditions, but responds more slowly than CRP.
Low Value
Low values are generally unremarkable.
Note: The normal value increases slightly with age.
Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
