Quick answer
This urine test measures levels of six heavy metals: arsenic, cadmium, cobalt, lead, mercury, and thallium. Creatinine is included to help interpret urine concentration. It is used when a broader look at metal exposure is needed, and a healthcare provider reviews the results with the exposure history.
What this test measures
A comprehensive urine metal panel looks for several toxic elements at once, which is useful when the source of exposure is uncertain or when multiple metals may be involved. Urine reflects recent elimination for many metals and is a common sample for arsenic, cadmium, and mercury testing. Creatinine adjustment helps account for how dilute or concentrated the urine is.
The sample is collected at a laboratory according to the collection instructions, which may specify a spot, first-morning, or timed collection. The panel reports each metal separately along with creatinine. Depending on the laboratory, arsenic or mercury speciation may be available to distinguish forms of the element with different health significance.
People order this panel after suspecting exposure through water, food, occupational materials, or hobbies, or when a clinician wants a comprehensive baseline. Results can be affected by recent meals and hydration, so they are interpreted alongside the collection details and the person's history.
- Arsenic (urine)
- Cadmium (urine)
- Cobalt (urine)
- Lead (urine)
- Mercury (urine)
- Thallium (urine)
- Creatinine (urine)
- Arsenic speciation when indicated
- Mercury speciation when indicated
Why people order this test
- Screen for multiple metal exposures in one collection
- Investigate suspected exposure from food or water
- Monitor an occupational or hobby-related exposure
- Provide a comprehensive baseline for a clinician
- Follow up on an abnormal single-metal result
How to prepare
Collection instructions come from the laboratory and may involve a spot, first-morning, or timed urine sample. Avoid major changes to diet or hydration before collection unless the laboratory advises otherwise. Follow the provided instructions.
Understanding your results
Reports are generally available within one to three business days. Each metal is compared with its own reference range, and creatinine helps put the urine concentration in context. A healthcare provider interprets the panel as a whole.

Frequently Asked Questions
Why is creatinine included in a metal panel?
Creatinine helps adjust for urine dilution so metal concentrations can be compared more reliably.
Does this test measure past exposure?
Urine mainly reflects recent elimination, so long-term exposure may require blood testing or repeat collections.
Can seafood change my result?
Yes. Recent fish or shellfish meals can raise arsenic and mercury readings, so mention your diet to the interpreting provider.
Is a timed collection required?
Some laboratories request a timed or first-morning sample, while others accept a spot collection. Follow the specific instructions.
What happens if a metal is above range?
A healthcare provider reviews the level, the collection details, and your history to decide whether repeat or additional testing is needed.
