Why This Biomarker Matters

Lead is a poison that damages the nervous system and kidneys. Elevated levels require identifying and eliminating exposure sources and medical monitoring to prevent irreversible health damage.

Overview

Lead is a toxic heavy metal that can accumulate in bones and organs, causing serious health problems. A urine lead test measures how much lead your body is excreting, which can reflect recent or chronic exposure. Lead exposure comes from contaminated water, paint, soil, and occupational sources. Elevated urine lead levels indicate concerning exposure and can cause neurological damage, cognitive problems, high blood pressure, and kidney damage. This test is important for detecting dangerous exposure.
