Copper in urine

General information:

The method is based on direct detection of copper in urine by atomic spectrophotometric absorption. The test has accuracy, sensitivity and specificity and is the gold standard in diagnostics. It is made in Germany.
The remaining methods of detecting copper in urine (colorimetric) are unreliable and misleading. Laborexpress 2000 offers its patients the best diagnostics.
Hypercupuria occurs in diseases such as Wilson's disease, hemochromatosis, biliary cirrhosis, thyrotoxicosis, infections and oncological diseases (including leukemia).
Low levels are found in malnutrition, hypoproteinemia, malabsorption and nephrotic syndrome. Excessive use of preparations containing metals (Zn) also affects the absorption of Cu in the gastro-intestinal tract.
The study complements the study of serum concentration of copper and ceruloplasmin.

Sample required:

24 hour urine, container to be stored at 2-8 °C (refrigerator) at all times
Collect in a sterile, dry, well-washed container (larger capacity). The first morning urine is discarded, the patient notes the time at which the 24-hour measurement will begin. The following urines are collected in the same container until the morning. The collection ends at the time the study began. The urine is then mixed well and a 20 ml amount is brought in a container to the laboratory. Please report the total amount (ml) in diuresis.
