Published: August 9, 2026Updated: August 16, 2026

Measures strontium and creatinine in a laboratory sample. Results may help assess strontium exposure and kidney function.

Quick summary

What is this test?

This laboratory test measures strontium, a naturally occurring trace element, and creatinine, a waste product filtered by the kidneys. The results may be reported as mass concentrations, meaning the amount of each substance in a specified volume of sample.

Why might I need this test?

Strontium measurement may be requested when exposure to strontium or related materials is suspected. Creatinine is commonly included to help evaluate kidney filtration, although the reason for testing and the relationship between the two results depend on the specimen and clinical situation.

How is the test performed?

A laboratory technician analyzes the submitted sample using a turbidimetric method. In this method, the amount of light scattered by the sample is used to estimate the concentration of the measured substance.

How do I prepare for the test?

Preparation depends on the specimen required. Follow the laboratory's instructions about fasting, fluid intake, and collection timing. If you are unsure, contact the ordering clinician or laboratory before the test.

Frequently asked questions

Is this the same as a routine kidney function test?
Not necessarily. Creatinine is a familiar kidney-related marker, but strontium is a separate trace-element measurement. The two results are interpreted together only when the laboratory and ordering clinician confirm that this is the appropriate test.
Does a high strontium result always mean poisoning?
No. A high result can reflect exposure, but it may also be influenced by supplements, diet, and other clinical factors. Your clinician will consider the amount and timing of any exposure along with the rest of your evaluation.
Do I need to fast before this test?
Fasting is not required for every version of this test, and preparation can vary by specimen and laboratory. Follow the specific instructions provided by the ordering clinician or laboratory.
