Chromium Random Urine
This urine test measures chromium levels, a heavy metal that Quest describes as able to damage the gastrointestinal, respiratory, immunological, reproductive and developmental systems. It is relevant to occupational or environmental exposure and to toxicity from excessive supplement intake.
About this test
The test measures the amount of chromium in a 2 mL random urine sample, collected in an acid-washed or metal-free plastic container, and analyzed using colorimetric methods together with inductively coupled plasma/mass spectrometry (ICP/MS). It also reports a chromium-to-creatinine ratio and the creatinine level in the same sample.
Chromium levels may be assessed in relation to occupational or environmental exposure to chromium, or in connection with toxicity that can result from excessive supplement intake. Quest notes that the need for chromium supplements is unproven, and that taking supplements in excess can lead to toxicity.
