What is this test?

This test measures the amount of strontium, a naturally occurring trace element, in a laboratory sample. It may also measure creatinine, which is commonly used to account for differences in urine concentration.

Why might I need this test?

Strontium testing may be ordered to evaluate exposure to strontium or to investigate how the body handles this element. Creatinine may be included as a comparison value, particularly when the specimen is urine.

How is the test performed?

A urine or stool sample is collected according to your laboratory's instructions and analyzed for the requested components. Some urine tests use a single sample, while others require all urine collected over a specified period.

How do I prepare for the test?

Follow the collection instructions provided by your laboratory, including whether a timed or 24-hour urine collection is required. For a stool sample, use the supplied clean container and avoid urine, water, or other contamination.

Frequently asked questions

Is strontium the same as strontium-90?
No. Strontium is an element that can have several radioactive and stable forms, and the test name does not clearly identify which form was measured. Ask the laboratory for the full analyte and method name.
Why is creatinine included with strontium?
Creatinine is commonly used to help account for how concentrated a urine sample is. This allows the strontium result to be interpreted more meaningfully than an unadjusted urine value.
How do I know which specimen to collect?
The abbreviated name appears to contain more than one specimen abbreviation. Confirm with the ordering clinician or laboratory whether urine, stool, or both are required before collecting your sample.
