Ceruloplasmin
The Ceruloplasmin blood test measures levels of ceruloplasmin, a protein involved in copper transport in the body. It is primarily used to investigate disorders of copper metabolism, including Wilson’s disease.

Details about Ceruloplasmin
What is the Ceruloplasmin Blood Test?
The Ceruloplasmin blood test measures the concentration of ceruloplasmin, a copper-binding protein produced by the liver. Ceruloplasmin plays a key role in transporting copper in the bloodstream and regulating copper balance in the body.
Copper is an essential trace element, but abnormal copper metabolism can lead to toxic accumulation or deficiency, affecting the liver, brain and nervous system. Ceruloplasmin levels provide important insight into how copper is being handled by the body.
This test is most commonly used in the investigation of Wilson’s disease, but it can also support assessment of liver disease, inflammation and certain neurological conditions.
Why do I need a Ceruloplasmin Blood Test?
A ceruloplasmin blood test is recommended when there is suspicion of abnormal copper metabolism or unexplained liver or neurological symptoms. It helps identify whether low or high ceruloplasmin levels may be contributing to disease.
You may benefit from this test if you have:
- Unexplained liver disease or abnormal liver enzymes
- Symptoms suggestive of Wilson’s disease
- Neurological symptoms such as tremor or coordination problems
- Psychiatric or behavioural changes without clear cause
- Kayser–Fleischer rings detected on eye examination
- Family history of Wilson’s disease
- Unexplained anaemia
- Chronic inflammation or infection
- Suspected copper deficiency or excess
Early detection is essential, particularly for Wilson’s disease, as treatment can prevent serious organ damage.

Your Ceruloplasmin Results Explained
Ceruloplasmin results are interpreted using UK laboratory reference ranges and clinical context.
Low Ceruloplasmin Levels
What this means:
- Ceruloplasmin below the reference range
Possible implications:
- Wilson’s disease
- Copper deficiency
- Severe liver disease
- Malnutrition or malabsorption
Low levels often require further copper studies.
Normal Ceruloplasmin Levels
What this means:
- Ceruloplasmin within the reference range
What it suggests:
- Normal copper transport and metabolism.
High Ceruloplasmin Levels
What this means:
- Ceruloplasmin above the reference range
Possible implications:
- Inflammation or infection
- Pregnancy
- Oestrogen use
- Certain liver conditions
Ceruloplasmin is an acute-phase protein, meaning levels can rise with inflammation.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
