What this test is
This test measures the concentration of lead in a urine sample. Lead is a metal that can be harmful if it builds up in the body, and urine testing can show how much lead is being excreted. It may be used to evaluate exposure over time or to monitor known exposure.
What it measures
- Urine lead concentration — reflects the amount of lead being excreted in urine
- Creatinine (sometimes) — may be measured to adjust for urine dilution
- Collection volume or timing — may be noted if a timed collection is used
What the test involves
The test requires collecting a urine sample, typically in a clean container at a lab or at home using a provided kit. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test if someone has symptoms that could be related to lead exposure or if there is a known risk of exposure at work or home. It can also be used to monitor people who have already been diagnosed with lead exposure.
Preparation
Preparation instructions can vary, so it is important to follow the specific directions provided by the collection lab. This may include avoiding certain foods or medications before the test.
How results are reported
Results are reported as a concentration of lead in urine, and the lab will provide a reference range for comparison. Reference ranges can differ between laboratories, so results should be interpreted in the context of the specific lab's range and the individual's situation.
