Erythrocyte Sedimentation Rate (ESR)

ESR measures how quickly red cells settle under defined laboratory conditions. It is an indirect indicator of inflammation.

Understanding the test

What the Erythrocyte Sedimentation Rate (ESR) test measures.

Also called Inflammation Marker (ESR)

ESR may support investigation or monitoring of certain inflammatory conditions. A previous result and a record of symptoms can be particularly helpful in follow-up.

When it may be requested

Looking for an inflammatory pattern

ESR reflects how quickly red cells settle under standardised conditions.

Following an established condition

The trend may help a clinician assess change alongside symptoms and other tests.

Before your sample

Prepare for collection

SpecimenWhole Blood (EDTA)
Your checklist0 of 2 ready

ESR alone requires no fast. Mention recent infection, pregnancy or anaemia and provide previous ESR or CRP results if this is a follow-up.

The clinician takes blood from a vein into a tube that keeps it from clotting. The collection team sends the labelled specimen to the laboratory.

Erythrocyte Sedimentation Rate (ESR)

Reading your result

A raised ESR has many possible explanations. Age, anaemia and factors other than active inflammation can change it.

What can affect it

  • Age, anaemia and pregnancy can influence ESR independently of inflammation.

Patient questions

Before you book

Is ESR interchangeable with CRP?

Both can reflect inflammation, but their timings and the factors influencing them differ. A clinician may use either or both depending on the question.

What does a high ESR mean?

A high ESR means an inflammatory process is likely somewhere in the body, but not where or why. Common causes are infection, including long-standing ones such as tuberculosis, rheumatoid arthritis, lupus, temporal arteritis and polymyalgia rheumatica, some cancers and chronic kidney disease. Your doctor uses symptoms, examination and further tests such as CRP to find the source.

What does a low ESR mean?

A low ESR carries little clinical meaning on its own and does not usually need explaining. Where it does matter, it reflects something slowing the settling of red cells: a high red cell count as in polycythaemia, abnormally shaped cells such as sickle cells or spherocytes, very high white cell counts, or low fibrinogen in advanced liver disease.
