What this test is

This test measures the amount of selenium in a urine sample. Selenium is a trace element that acts as an antioxidant and supports thyroid and immune function. Urine selenium mainly reflects recent intake and excretion, so it is often used alongside other tests.

What it measures

  • Urine selenium — reflects recent selenium intake and excretion
  • Creatinine (if measured) — helps adjust for urine concentration
  • Collection volume (for 24-hour) — used to calculate total daily excretion

What the test involves

You will collect a urine sample, usually a spot sample or a 24-hour collection, following the lab's instructions. The sample is then sent to the laboratory for analysis.

Why it is often ordered

A clinician may order this test to monitor workplace exposure to selenium or to help assess whether selenium levels are too low. It can also be used to follow up on abnormal findings from other tests.

Preparation

Preparation depends on the type of urine collection and the laboratory's procedures. Follow the specific instructions provided by the collection lab.

How results are reported

Results are reported as a concentration or total amount of selenium in the urine, often with a reference range. Reference ranges vary by laboratory and by the type of collection, so your result should be interpreted in that context.

Before you go

  • Whether a spot or 24-hour urine collection is required
  • Any dietary or supplement restrictions before collection
  • How and when to return the sample to the lab
