In addition to the required screening at ages one and two, assessment of risk for high-dose lead exposure should be done at least annually for each child six months to six years of age (up to age 18, if indicated). These questions serve as a risk assessment tool based on currently accepted public health guidelines. Children found to be at risk for lead exposure should receive a blood lead test whenever such risk is identified.
If the answer to any of the above questions is YES, then the child is considered to be at risk of high dose lead exposure and should be screened with a blood lead test.
