Should my child be screened for lead?
The only way to know for sure if your child has been exposed to lead is with a blood test. Lead screening tests sometimes take blood from the finger, but it is better and more accurate to take the blood from a vein in the arm. The test measures the amount of lead in the blood. If you think that your child has been exposed to lead, talk with your pediatrician about getting a blood test to check for lead.
