Lead (Blood)


This blood test 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:

If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.

Disclaimer: A health care provider should evaluate a deviation from normal ranges.
