Urine is the gold standard for assessing chronic exposure to metals such as cadmium and arsenic. While blood tests are better for acute or recent poisoning, urine levels reflect the body's ongoing toxic burden and excretion rate. This 14-metal panel provides a comprehensive look at your baseline excretion.

Yes. For the most accurate mercury toxicity test results, avoid all seafood, seaweed and fish oil supplements for at least 48 hours prior to collection. These foods can cause temporary, harmless increases in arsenic and mercury levels.

Once the lab receives your sample, results for your heavy metal urine test are typically available in your secure digital portal within 7 business days.

Heavy metal exposure occurs when metals such as lead, mercury, arsenic or cadmium enter the body through sources such as food, water, air or occupational environments.

Arsenic exposure can occur through contaminated water, certain foods and environmental sources. Measuring urinary arsenic can provide information about recent exposure.

Mercury can come from sources such as certain types of seafood and environmental exposure. Measuring it can help assess recent or ongoing exposure.

Lead is a toxic metal that may be encountered through older paints, industrial environments, contaminated dust or other environmental sources.

Yes. Urinary heavy metal levels can vary depending on recent exposure, diet and how the body processes and excretes different metals.
