What is this test?

This test measures the amount of vanadium and creatinine in urine collected over 24 hours. Vanadium is a trace element that can enter the body through certain foods, supplements, workplace exposure, or contaminated materials. Creatinine is a waste product made by the muscles and is measured to help evaluate how much urine was collected and provide context for the vanadium result.

Why might I need this test?

A clinician may order this test to assess possible vanadium exposure, particularly after workplace or environmental contact. It may also be used to monitor people taking vanadium-containing supplements or to investigate symptoms that could be related to exposure.

How is the test performed?

You collect all urine into a special container for a full 24-hour period according to the laboratory's instructions. The laboratory then measures vanadium and creatinine in the collected sample. Because incomplete collections can affect results, the collection time and any missed samples should be reported.

How do I prepare for the test?

Follow the laboratory's collection instructions carefully, including the specified start and end times. Tell your clinician about occupational exposure, supplements, medications, and any recent changes in exposure. Do not deliberately change your diet or stop prescribed medicines unless your clinician advises you to do so.

Frequently asked questions

What does an elevated vanadium level mean?
It may indicate increased recent exposure, such as from certain occupations, environmental sources, or supplements. Your clinician will interpret the result using your history and other findings because a single measurement does not establish the cause.
Why is creatinine measured with vanadium?
Creatinine helps assess the adequacy of the 24-hour urine collection and provides context when interpreting the vanadium result. An unusually low creatinine in a supposed 24-hour collection may suggest that some urine was missed.
How should I collect a 24-hour urine sample?
Use the container and exact collection schedule provided by the laboratory, and record when the collection began and ended. If you miss a sample or the collection is shorter or longer than instructed, contact the laboratory or clinician for guidance.
