What this test is
This test analyzes a urine sample to detect and measure mercury levels. It is typically used to evaluate exposure to inorganic mercury or elemental mercury vapor. The test does not diagnose any condition on its own; results are interpreted by a clinician alongside other findings.
What it measures
- Urine mercury concentration — Reflects the amount of mercury being excreted in urine at the time of collection.
- Creatinine (if measured) — Used to adjust mercury levels for urine dilution, helping account for how concentrated the sample is.
- Collection type — Indicates whether the sample was a spot collection or a timed collection, which affects interpretation.
What the test involves
You will provide a urine sample, usually by urinating into a sterile cup at a collection site. In some cases, a 24-hour urine collection may be requested, which involves collecting all urine over a full day.
Why it is often ordered
A clinician may order this test if there is concern about workplace, environmental, or dietary exposure to mercury. It can also be used to monitor levels in people who have known exposure or symptoms that might be related to mercury.
Preparation
Specific preparation instructions are provided by the collection lab and may include avoiding certain foods or medications beforehand. Always follow the lab's instructions exactly to ensure accurate results.
How results are reported
Results are reported as a concentration of mercury in urine, often in micrograms per liter or micrograms per gram of creatinine. Reference ranges vary by laboratory and by the type of collection, so your clinician will interpret your result in the context of your health and exposure history.
