A 29-year-old woman had a complete hydatidiform mole evacuated 3 weeks ago. Her serum β-hCG has declined appropriately and is currently 50 mIU/mL. According to standard guidelines, how long should she continue to have weekly β-hCG monitoring after the first undetectable level?
- A 1 month
- B 3 months
- C 6 months ✓
- D 12 months
Correct answer: C. 6 months
Explanation
After a complete hydatidiform mole, β-hCG is monitored weekly until undetectable, then monthly for 6 months. Partial mole requires only 1 month of negative monitoring. One month is too short, and 12 months is not standard for complete mole.
