Blood tests for children are recommended at which ages?

Blood tests for children are recommended at which ages?

• A. Ages 1-2
• B. Ages 3-4
• C. All children regardless of age
• D. Ages 5-6

Answer: (A)

Focusing screening in early childhood captures the period when lead exposure can cause the most harm and early intervention is most effective. The standard baseline blood lead test is recommended around ages 1 and 2, because toddlers are more likely to encounter lead in dust, soil, or deteriorating paint and are more susceptible to absorption and developmental impacts. After this early window, testing is typically guided by risk factors rather than universally scheduled at every age. So, ages 1–2 is the best fit for the routine, universal screening recommendation.
