What is this test?

This test measures the amount of titanium in urine relative to creatinine, a waste product used to account for differences in urine concentration. It can help assess recent exposure to titanium or titanium-containing materials.

Why might I need this test?

The test may be used for workplace or environmental health monitoring, particularly in people exposed to titanium-containing dust, pigments, metals, or manufacturing materials. It may also be ordered when a clinician is evaluating possible exposure-related health concerns.

How is the test performed?

A urine specimen is collected and analyzed for titanium and creatinine. Reporting the results as a ratio helps reduce the effect of variations in urine concentration that could otherwise make the titanium result less useful.

How do I prepare for the test?

Follow the laboratory's urine-collection instructions and provide the type of sample requested. Inform the clinician and laboratory if you work with titanium-containing materials, since workplace exposure information is important for interpreting the result.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a urine titanium test measure?
It measures titanium excreted in the urine. The result may be reported relative to creatinine to account for how concentrated the urine sample is.
Who may need this test?
It may be ordered for occupational or environmental exposure monitoring, especially in workers handling titanium-containing dust, pigments, or manufacturing materials.
Does an elevated result mean titanium poisoning?
Not by itself. An elevated result can indicate recent exposure, but interpretation also depends on the work history, urine collection conditions, and other clinical information.
