&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;OVERVIEW&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;The Nickel/Creatinine Ratio, Random, Urine (NIUC) test measures the concentration of nickel in a urine sample, adjusted for creatinine levels. This test is often used to assess exposure to nickel, a metal that can be toxic at high levels. The ratio helps normalize nickel concentration relative to kidney function since creatinine is a byproduct of muscle metabolism and is excreted at a constant rate. This test is typically performed on a random urine sample, meaning it is not necessary to collect it at a specific time of day. It is useful in occupational health to monitor nickel exposure in workers or in medical investigations of potential nickel toxicity.&lt;/span&gt;&lt;/p&gt;
