What is the frequency of lead testing for high-risk patients?

The recommended frequency of lead testing for high-risk patients, such as those living in areas with higher lead exposure or in homes with lead hazards, is vital for the early detection of lead poisoning. Testing is typically recommended at 12 months and again at 24 months of age. These ages are critical because they coincide with developmental milestones and increased mobility in children, which can expose them to lead hazards in their environment.

At 12 months, children are becoming more active and may have increased exposure through hand-to-mouth behaviors, while the follow-up at 24 months helps ensure that any potential lead exposure is identified before the child enters school age. Early identification of lead exposure is essential to prevent long-term health effects, including cognitive impairment and developmental delays.

Other options, while they include lead testing, do not align with the recommended frequency for high-risk children as effectively. For instance, annual testing or testing only at 24 months may not sufficiently monitor children who are at an elevated risk for lead exposure. Comprehensive screening at the critical ages of 12 and 24 months provides a more effective strategy for ensuring children's health in environments where lead exposure is a concern.
