24 Hrs Urinary Copper

The 24-Hour Urinary Copper Test is a laboratory investigation used to measure the total amount of copper excreted through urine over a 24-hour period.

Copper is an essential trace mineral that supports iron metabolism, energy production, connective tissue formation and normal nervous system function. However, abnormal copper accumulation or excretion may be associated with certain medical conditions.

This test helps healthcare professionals evaluate copper metabolism, investigate suspected Wilson's disease and monitor copper-related disorders.

What Does This Test Check?

• Total copper excretion over 24 hours

• Abnormally high urinary copper levels

• Copper metabolism abnormalities

• Possible copper accumulation associated with Wilson's disease

• Response to treatment in certain copper-related conditions

Sample Requirements

• Sample Type: 24-Hour Urine

• Collection Period: Complete 24-hour urine collection

• Test Category: Laboratory – Clinical Biochemistry

• Collection Container: Laboratory-approved trace-element collection container

Patient Preparation

• Follow your healthcare provider's instructions regarding medications and supplements.

• Inform your doctor if you are taking copper supplements or medications used to treat Wilson's disease.

• Do not stop or change prescribed medications without medical advice.

• Use only the laboratory-approved collection container to minimize contamination.

• Follow the laboratory's specific storage and transportation instructions.

24-Hour Urine Collection Instructions

1. Day 1 – Morning: Empty your bladder into the toilet after waking up. Do not collect this first urine. Record the exact time.

4. Storage: Store the urine collection according to the laboratory's instructions.

5. Submission: Deliver the complete sample to the laboratory as instructed.

Relevant Conditions

• Wilson's Disease

• Copper Metabolism Disorders

• Copper Accumulation Disorders

• Monitoring of Wilson's Disease Treatment

Important Information

The 24-Hour Urinary Copper Test may be used alongside other investigations, such as serum copper, ceruloplasmin and liver-related assessments, when clinically indicated.

Urinary copper results alone cannot definitively diagnose or exclude Wilson's disease. Results should be interpreted by a qualified healthcare professional alongside symptoms, medical history and other investigations.

Please confirm test availability, collection container requirements and sample handling instructions with the laboratory before booking.
