Creatinine urine

Nickel - urine
Learn more
This test measures the absolute amount of nickel present in your urine sample. Nickel is a heavy metal that you can be exposed to through jewellery (particularly costume jewellery and piercings), occupational settings, cooking utensils, and certain foods. Your body eliminates nickel primarily through urine, so measuring urinary nickel can help identify recent exposure.
Nickel - creatinine
Learn more
This test measures nickel levels in your urine adjusted for creatinine concentration, providing a more accurate picture of nickel exposure than measuring nickel alone. Because urine can be more diluted or concentrated depending on how much fluid you've consumed, adjusting for creatinine (a waste product excreted at a fairly constant rate) standardises the result and eliminates the effects of hydration status. This makes the nickel:creatinine ratio the gold standard for assessing nickel exposure from sources such as jewellery, occupational environments, or dietary intake. Elevated ratios may indicate ongoing exposure and can help explain symptoms such as contact dermatitis or other nickel-related health concerns.
This test detects nickel in urine but doesn’t measure long-term accumulation in tissues. Further toxicology tests may be needed for a full assessment.
You can come into contact with nickel in two ways; through breathing in dust and fumes containing nickel or through contact with the skin. Exposure to nickel can cause irritation of the skin and eyes, allergic reactions in the skin and respiratory tract, asthma, inflammation of the lungs, and cancer of the lungs and nose.
The most common harmful health effect of nickel in humans is an allergic reaction. Approximately 10-20% of the population is sensitive to nickel.
Nickel can be found in alloys, particularly nickel/copper and nickel/chromium, in the manufacture of stainless steel, coins, magnets, chemical and food process equipment, polishing or other processes on stainless steel and nickel alloy articles, welding of nickel and alloys and when using welding rods containing nickel, the electroplating industry, pigments for paint, pottery, glass and plastics and catalysts in the chemical industry. Nickel is also often found in jewellery.
