Test for ceruloplasmin


A ceruloplasmin test: what is it?

A ceruloplasmin test determines the level of ceruloplasmin in a blood sample. Your liver binds copper to a protein to create ceruloplasmin. In order for your blood to deliver copper to the areas of your body that require it, your liver releases ceruloplasmin into the bloodstream.

Your body needs copper for many vital functions, such as the synthesis of energy, blood vessels, and melanin, the pigment that gives your skin and eyes their color. Copper promotes brain growth and aids in the body’s utilization of iron. It also supports the health of your immune and neurological systems.

Little levels of copper are all you need to be healthy. The majority of people obtain adequate copper through their diet. Shellfish, nuts and seeds, organ meats like beef liver, wheat bran cereals, and chocolate are good sources of copper.

Normally, ceruloplasmin contains the majority of the copper found in your blood. Therefore, illnesses involving an excess or deficiency of copper in the body can be diagnosed with the use of ceruloplasmin testing.

Other names: serum ceruloplasmin, copper oxidase, ferroxidase, CP, ceruloplasmin blood test, and ceruloplasmin.


For what purpose is it used?

In order to diagnose Wilson’s disease, a ceruloplasmin test is typically done in conjunction with other assays. Wilson disease is an uncommon hereditary condition that stops the body from eliminating excess copper.


A dangerous accumulation of copper in the liver, brain, eyes, and other organs can result from Wilson disease. High copper levels have the potential to seriously harm organs and even be fatal.


Low copper problems can also be diagnosed with the aid of ceruloplasmin assays. Low copper levels are rare; however, they can be brought on by things like:


Malnutrition is a condition that arises from inadequate consumption of vitamins, minerals, and other essential nutrients in the diet.

A disease known as malabsorption occurs when the body has difficulty absorbing nutrients from a diet. Malabsorption can result from a number of illnesses, including celiac disease.

Menkes syndrome, sometimes known as Menkes sickness, is an uncommon, hereditary condition that impairs the body’s capacity to utilize copper. Typically, the first few months of life are when symptoms appear.

Overconsumption of zinc pills, which may impair your body’s ability to utilize copper
Frequent ceruloplasmin testing may be performed to monitor a patient with a diagnosis of either too high or too low blood copper levels and to assess the efficacy of treatment.


Ceruloplasmin assays are primarily employed in conjunction with assays that quantify copper concentrations in blood or urine.


What makes a ceruloplasmin test necessary?

If you exhibit Wilson disease signs, your doctor could prescribe a ceruloplasmin test. The condition is inherited, but symptoms don’t show up until copper accumulates in the liver, brain, or other organs. Although the typical age range for this is 4 to 40, symptoms can manifest at any point in life.


Depending on the bodily areas afflicted, Wilson’s illness can cause a wide range of symptoms. As an illustration:


  • Vomiting and nausea
  • Discomfort in the upper abdomen (belly)
  • A change in color from normal for either the feces (poop) or the urine
  • The illness is known as jaundice, which makes your skin and eyes yellow.
  • Hemolytic anemia is a form of anemia in which the body breaks down red blood cells more quickly than it can produce them.
  • Fluid accumulation causing swelling in your lower limbs, foot, or abdomen
  • Skin irritation
  • Speech, swallowing, or motor coordination issues
  • Shivers
  • Uncontrollably stiff muscles and/or jerky, abrupt movements
  • Mental health conditions such as psychosis, sadness, or anxiety
  • Your irises, or the colored section of your eyes, have rings that are either green, gold, or brown.
    Even if you don’t have any symptoms, you can still need a test if Wilson’s illness runs in your family.

This test might also be necessary if you experience any of the following symptoms, which could indicate low copper levels:


Abnormally low concentrations of neutrophils, a kind of white blood cell.

  • Osteoporosis: a disorder that weakens and easily fractures bones
  • Weary
  • Tingling in the feet and hands
  • Pale skin

If your newborn exhibits signs of Menkes syndrome, they might require a ceruloplasmin test. Usually, the onset of symptoms occurs between two and three months of age in babies. They could consist of:


  • Hair that is thin, colorless, brittle, and extremely tangled
  • Lanky muscles
  • Convulsions
  • Gradual development and weight gain

Most kids with Menkes syndrome pass away in their first few years of life if they are not treated. Some babies may live longer if treatment begins within the first month of life. However, the illness still has a tendency to worsen over time despite treatment.


You might require routine ceruloplasmin testing if you have been diagnosed with abnormal copper levels in order to monitor your condition and assess the efficacy of your treatment.


What takes place in a test for ceruloplasmin?

Using a tiny needle, a medical practitioner will draw blood from a vein in your arm. A tiny amount of blood will be collected into a test tube or vial following the insertion of the needle. The needle may sting a little as it enters or exits your body. Usually, this takes under five minutes.

Is there anything I should do to get ready for the test?

For a ceruloplasmin test, there are no specific preparations required.


Does taking the exam carry any risks?

A blood test has virtually minimal danger associated with it. The site of the needle injection may bruise or cause some pain, but most side effects pass quickly.


What does the outcome signify?

A ceruloplasmin test’s results by themselves are unable to diagnose any illnesses. The findings of other tests, such as those that gauge the level of copper in your blood or urine, will determine how your test results are interpreted.


Your provider will evaluate all of your test results, symptoms, medical history, and family history in order to determine a diagnosis. Find out from your healthcare practitioner what your ceruloplasmin levels indicate about your health.


Generally speaking, lower than normal ceruloplasmin levels could indicate improper copper utilization by your body. Low ceruloplasmin levels could indicate:


  • Wilson illness, despite the fact that ceruloplasmin levels are occasionally normal in this condition.
  • Menkes illness
  • severe illness of the liver
  • renal illness
  • a copper deficiency brought on by malnutrition and/or starvation


Elevations of ceruloplasmin over normal could be associated with:

  • Heart conditions
  • The arthritis rheumatoid
  • Leukemia
  • Hodgkin lymphoma
  • Damage, inflammation, or infection


However, elevated ceruloplasmin levels do not always indicate a disease that requires medical attention. Birth control pills, pregnancy, and some medications, such as estrogen therapy for menopause treatment, can all result in elevated blood ceruloplasmin levels. Elevations in ceruloplasmin are rarely the result of eating too much copper.
