Serum iron levels can be a helpful component of the diagnostic work-up for lead poisoning, as lead can interfere with the absorption of iron, leading to decreased levels. Folate levels can also be affected by lead poisoning, but serum iron levels are a more specific marker. Sodium and lactic acid levels are not typically affected by lead poisoning.
