Caeruloplasmin (Ceruloplasmin)

Test Background

Copper is an essential trace element. It is required for ferro-oxidase activity which is an essential stage for incorporation of iron into haem. Copper is absorbed in the intestines and then transported to the liver, where it is stored or used in the production of a variety of enzymes.

Caeruloplasmin is a copper-containing enzyme that plays a role in the body’s iron metabolism. In the blood, 95% is bound to caeruloplasmin and 5% is free. It is used in conjunction with serum copper assay to help diagnose Wilson’s disease and evaluate copper metabolism.

Clinical Indications

Decreased serum copper and caeruloplasmin, plus an elevated urinary copper, are closely associated with Wilson’s disease.

Symptoms include: anaemia, nausea with abdominal pain, jaundice, dysphagia, tremors, behavioural changes, Kayser-Fleischer rings and tremors.

NWLP operates UKAS accredited medical laboratories as per the references below. The current scope of accreditation for all NWLP’s laboratories can be found on the UKAS website.

See the following UKAS ref numbers:

  • Clinical Biochemistry Ref: 8673
  • Haematology and Blood Transfusion Ref: 8674
  • Infection & Immunity Sciences (Including Immunology, Virology, Microbiology and Histocompatibility and Immunogenetics ) Ref: 8659
  • Cellular Pathology (Including Histopathology, Cytology and Molecular Pathology) Ref: 9615

If you require copies of our certificate of accreditation and associated documentation please contact Imperial.nwlpcustomerservice@nhs.net.

UKAS requires the laboratories to be accredited for a particular repertoire/scope (ISO15189), any changes or additions to repertoire require assessment by UKAS (extension to scope).
