A lead urine test measures how much lead is in your urine. It is usually ordered to check for recent or ongoing exposure to lead, or to monitor levels during and after treatment for lead poisoning.

What it measures

  • Lead — The amount of lead in the urine sample.
  • Creatinine — A substance that helps adjust for how diluted your urine is.
  • Lead-to-creatinine ratio — A calculated value that accounts for urine concentration.
  • Other heavy metals — Sometimes tested at the same time, such as arsenic or mercury.

Who it is for

A doctor may order this test if you have symptoms of lead exposure, work with lead, or have been treated for lead poisoning. It is also used to monitor people with known exposure.

Preparation

No fasting is needed. Your doctor may ask you to avoid certain foods or medications before the test, but usually no special preparation is required.

Results and what they mean

Results are reported as the amount of lead in your urine, often adjusted for creatinine. Your doctor will interpret the results based on your exposure history, symptoms, and other tests. This information is general and not a substitute for medical advice.

Requesting the Lead Urine Test in California

Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. Because the region is uneven, coastal metros, inland towns, and rural counties with very different access to testing — worth planning around when you book.
