Copper, Random Urine
Also known as: Cu, Urine
Use
Monitor exposure to copper
Special Instructions
When collecting random urine for this test, do not use any preservatives. Routine analysis preservatives may contain mercuric oxide which interferes with metal testing, so submit a separate urine specimen without additives for metal tests.
Limitations
The diagnosis of Wilson's disease or other copper-related conditions cannot rely solely on urinary copper levels. Increased urinary copper may also occur in conditions such as Indian childhood cirrhosis or chronic active hepatitis. Additional testing, including serum copper and ceruloplasmin, is needed to differentiate between these conditions. Furthermore, overexposure to copper is rare, except in industrial settings, which may influence urine copper levels.
