In adults, Pb poisoning can cause irritability, poor muscle coordination, and nerve damage to the sense organs and nerves controlling the body. It also can retard fetal development even at relatively low levels of Pb. In children, Pb poisoning can cause brain damage, mental retardation, behavioral problems, anemia, liver and kidney damage, hearing loss, hyperactivity, developmental delays, other physical and mental problems, and in extreme cases, death. However, since adverse effects may occur at lower levels than previously thought, various Federal agencies are considering whether this level should be lowered further. Yes, your doctor or health center can conduct blood tests to determine Pb concentrations in your blood.
Blood tests are inexpensive and sometimes free.
Pb in bone and teeth can be measured using x-ray techniques, but this test is not used very often. In communities where houses are old and deteriorating, residents are encouraged to take advantage of available screening programs offered by local health departments and to have children checked regularly for Pb poisoning. Because the early symptoms of Pb poisoning are similar to other illnesses, it is difficult to diagnose Pb poisoning without medical testing. This screening is especially critical for children under 36 months of age. Decisions about further Pb testing should be based on previous blood-lead test results, and the child's risk of Pb exposure.
