Lead (Urine)


This 24-hour urine test is used to measure lead levels. Lead and mercury are poisonous for similar reasons, as they are both considered heavy metals. Lead is the main cause of childhood heavy metal poisoning, so it is important to consider the environment you grew up in.


Historically lead was found in paint, pipes and drains in older homes. Today, lead can also be found in plumbing, fuel additives, ammunition, PVC plastics, X-ray shielding, seafood and vaccines that contain Thimerosal. Lead is readily absorbed in bone because lead resembles calcium, making it more absorbable when calcium levels are abnormally low. Even at low levels, lead can cause irreversible damage. Lead toxicity affects the brain, nervous system, bones, kidneys and thyroid. Individuals experiencing chronic health challenges are encouraged to be evaluated for lead and other heavy metal toxicity.

Test Preparation For Optimal Results:

A 24-hour urine collection must be submitted for this test to be completed. The specimen container for the 24-hour urine collection can be picked up at any Lab Corp lab collection site. The Lab Corp staff will be happy to answer any questions or concerns. Instructions for a 24-hour urine test are as follows:1. The specimen collection starts by discarding the first urine passed upon rising. It is important to empty the
bladder completely.
2. Except for the discarded urine passed upon the morning rise, place ALL of the urine passed during the next
24 hours in the specimen container obtained at the Lab Corp collection site. Urine passed during bowel
movements must be included in the collection process.
3. Maintain the specimen container at room temperature.
4. Avoid contact with metal during the collection process.
5. At the same time the following morning, empty the bladder completely one more time and add this sample to
the collection container. This completes the collection process.
6. Be sure the lid to the specimen container is on securely. Take the collection container to the Lab Corp
collection site as soon as possible.Disclaimer: A health care provider should evaluate a deviation from normal ranges.
