Ceruloplasmin is a protein made by the liver that carries most of the copper in the bloodstream. It is primarily used to help diagnose Wilson's disease and copper metabolism disorders.
Category: Liver Function
Also known as: ceruloplasmin, cp, caeruloplasmin, Copper oxidase, ceruloplazmin
Reference range: 20–35 mg/dL (Source: ABIM)
Standard unit: mg/dL
High values may indicate
High ceruloplasmin may indicate infection, inflammation, rheumatoid arthritis, pregnancy, or use of oral contraceptives.
Low values may indicate
Low ceruloplasmin may indicate Wilson's disease, Menkes disease, severe liver disease, copper deficiency, or malnutrition.
Frequently asked questions
- What is a normal Ceruloplasmin level?
- A typical reference range for Ceruloplasmin is 20–35 mg/dL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Ceruloplasmin measured in?
- Ceruloplasmin is most commonly reported in mg/dL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Ceruloplasmin reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Ceruloplasmin over time?
- Yes. Upload results from any lab and BloodId charts your Ceruloplasmin over time against its reference range, so you can see whether the trend is rising, falling, or stable.
