Lead Poisoning Testing
|
|
Children should be screen for lead poisoning beginning at the age of six to nine months by having parents and care givers review the risk factors for lead poisoning. Children found to be at risk should be tested with a finger stick blood sample or a venous blood level. If your child is not at risk or if his blood level is normal, then he should be screened and retested when appropriate.
Depending on your child's initial screening blood lead level, he should be retested according to the classification table below.

Other tests that can be performed include a complete blood count to look for anemia and basophilic stippling of red blood cells, xrays of the long bones of the legs to look for lead lines, and a urinalysis, serum creatine and BUN to test for kidney damage. An x-ray of the abdomen may also be done to look for recently ingested lead paint or lead weights.
