Copper 24-Hour Urine

• Test Name: Copper 24-Hour Urine Test
• Test Type: Urine analysis
• Specimen Required: 24-hour urine collection
• Methodology: Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectrometry (AAS)
• Purpose: Measures the amount of copper excreted in the urine over a 24-hour period, which helps assess copper metabolism and diagnose related disorders.

• Diagnosis: Primarily used to diagnose Wilson’s disease, a genetic disorder that causes copper accumulation in the body.
• Monitoring: Helps monitor the effectiveness of treatment in patients with Wilson’s disease or other disorders involving abnormal copper metabolism.
• Evaluation: Assesses copper excretion in patients with unexplained liver disease, neurological symptoms, or hemolytic anaemia.
• Toxicity Assessment: Used to evaluate potential copper toxicity due to exposure to high levels of copper.

Components:

• 24-Hour Urine Collection: Patients collect all urine produced in a 24-hour period for analysis.
• Copper Quantification: The test measures the total amount of copper excreted in the urine during the collection period.
• Volume Measurement: The total volume of urine collected is measured to ensure accurate results.

• Normal Findings: Normal copper excretion typically ranges from 15 to 60 micrograms per 24 hours, depending on dietary intake and other factors.
• Elevated Levels: Higher-than-normal copper levels may indicate Wilson’s disease, particularly if combined with other clinical findings such as low serum ceruloplasmin levels or liver abnormalities.
• Decreased Levels: Low copper excretion may suggest dietary deficiency or other metabolic issues but is less commonly associated with significant disease.
• Further Evaluation: Abnormal results typically require further diagnostic testing, such as serum copper and ceruloplasmin levels, liver biopsy, or genetic testing for Wilson’s disease.

• Quantitative Measurement: The result is reported as the total micrograms of copper excreted in 24 hours.
• Interpretation: Results must be interpreted in the context of the patient’s clinical history, dietary copper intake, and other laboratory findings.
• Turnaround Time: Results are generally available within 2 to 5 days, depending on laboratory processing times.
• Report: The final report includes the total amount of copper excreted and reference ranges for comparison.

Q. What is the Copper 24-Hour Urine Test?
