Urine Copper Test
Urine Copper Test
This test measures copper levels in the urine. The Copper Urine Test can be done on either a single random sample or a 24-hour specimen. Copper is a mineral which plays a role in a number of bodily processes. Copper is found in a number of foods such as nuts, chocolate, shellfish, grains, and liver. Healthy copper levels contribute to energy production and nervous system function. Most copper in the body is bound to the enzyme Ceruloplasmin. Copper deficiency is rare but can be caused by malabsorption disorders such as Celiac and Cystic Fibrosis. Wilson Disease, an inherited disorder, can cause the liver to store excess copper which can lead to toxicity. Cooper exposure can also come from environmental pollution, industrial settings, or drinking water transported by aging copper pipes. Symptoms of copper toxicity include nausea, fatigue, uncontrolled shaking, loss of coordination, jaundice, and involuntary muscle contractions.
A copper urine test is usually ordered to aid in the diagnosis of Wilson Disease. It can also be ordered when a person is suspected of having copper toxicity or deficiency. Urine copper testing is typically done as a followup to irregular results on a Copper Blood Test.
Turnaround for this test is typically 2-4 business days.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
When placing your order, please state if you require a 24-hour collection for this urine copper test. For 24-hour specimens, void at 8 AM and discard the specimen. Then collect all urine including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM the next morning). Screw the lid on securely.
