Ceruloplasmin is a protein produced by the liver that helps transport copper in the blood. A ceruloplasmin test is used to measure the level of ceruloplasmin in the blood. It is typically ordered when a healthcare provider suspects that a patient has a copper metabolism disorder, such as Wilson’s disease or Menkes disease, or when a patient has symptoms of anemia, joint pain, or neurological problems.

Pre-test preparation:

There is no specific preparation required for a ceruloplasmin test.

Testing method:

The ceruloplasmin test is a blood test. A healthcare provider will take a sample of blood from the patient’s arm, usually from a vein in the elbow or the back of the hand. The blood sample will be sent to a laboratory for analysis.

Symptoms for prescribing this test:

Symptoms of copper metabolism disorders that may lead to a ceruloplasmin test include:

• Neurological problems, such as tremors, difficulty walking, and speech difficulties
• Anemia
• Joint pasuch as hypokalemia (low potassium levels) or hyperkalemia (high potassium levels).
• Jaundice (yellowing of the skin and eyes)

Diagnosis:

The ceruloplasmin test results will be used in conjunction with other tests, such as a copper and copper/zinc ratio test, to help diagnose a copper metabolism disorder.

Reference range and normal values:

The normal range for ceruloplasmin levels in the blood is typically between 20-40 mg/dL. However, this may vary slightly depending on the laboratory that performs the test.
