What is this test?

This test measures the amount of scandium, a trace metal, in urine collected over 24 hours. The result is compared with the amount of creatinine in the same collection to account for differences in urine concentration.

Why might I need this test?

The test may be ordered for people who work with metals or have another possible source of ongoing scandium exposure. It can also be used during workplace or environmental health evaluations.

How is the test performed?

All urine produced during a full 24-hour period is collected in a special container provided by the laboratory. The collection time, total urine volume, and scandium and creatinine measurements are used to calculate the reported result.

How do I prepare for the test?

Follow the laboratory's instructions for the exact collection start and finish times, and include every urine sample during that period. Tell the laboratory about occupational exposure, supplements, medicines, and any recent metal-containing procedures or products.

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Is this the same as a routine creatinine test?
No. Creatinine is measured in the same 24-hour collection and is used to adjust the scandium result for urine concentration.
What can cause an elevated result?
Possible causes include occupational or environmental exposure, recent contact with scandium-containing products, supplements, or contamination of the urine collection container.
What if I miss part of the 24-hour collection?
A missed sample can make the result unreliable, especially if the collection volume and timing are incorrect. Contact the laboratory or your clinician for guidance about repeating the test.
