The Blood Lead Levels (BLL) testing will show the amount of lead that exists in the blood. Lead poisoning can affect the bones, kidneys and thyroids through exposure. It is the main cause of childhood heavy metal poisoning. It used to be used in paint, pipes and drains in homes, and was ingested through flaking, weathering, and dust. Lead can also be found in plumbing, fuel additives, ammunition, PVC plastics and x-ray shielding. Blood tests should be performed if lead poisoning is suspected. The test does not show the actual amount of lead that is in the body. An elevated level of lead in the blood for an adult is 25 grams per deciliter.
Prior to having this test administered please avoid red wine and seafood for 72 hours.
