A 40-year-old battery worker has a blood lead level of 75 µg/dL without symptoms. Which is the most appropriate chelation agent?
- A Calcium disodium EDTA ✓
- B Succimer (DMSA)
- C Penicillamine
- D Dimercaprol
Correct answer: A. Calcium disodium EDTA
Explanation
For asymptomatic lead poisoning with blood lead level above 70 µg/dL, intravenous calcium disodium EDTA is the drug of choice. Succimer is used orally for levels 45-69 µg/dL. Penicillamine and dimercaprol are alternatives but not first-line for this level.
