Uranium, Urine
Use
Measurement of uranium in urine provides guidance in assessing possible exposure to uranium, detecting elevated levels that may result from environmental or occupational sources. Interpretation should consider potential contamination during collection, and confirmation of unexpected elevated results with a repeat specimen is recommended.
Special Instructions
Patient should avoid exposure to gadolinium-based contrast media for 48 hours prior to specimen collection. Supply required: NMS Acid Washed “Precleaned”, 10 mL (T619). Specimen must be submitted in acid washed or trace metal‑free plastic container. One specimen per order.
Limitations
Specimens for elemental testing are susceptible to environmental contamination during collection. Elevated levels may be artifactual; therefore, unexpected elevated results should be verified by testing another specimen in a trace metal‑free container. Reference values are laboratory‑derived and may vary across populations.
