Which option describes a typical interval for MRD monitoring?

• A. Every 1-2 weeks
• B. Every 3-6 months
• C. Every 2 years
• D. Biweekly

Answer: (B)

MRD monitoring is about checking for very small numbers of remaining cancer cells during remission without overburdening the patient with frequent testing. The most practical and standard interval is every 3-6 months, which strikes a balance between catching early signs of relapse and not over-testing. Testing more often (every 1-2 weeks or biweekly) is usually reserved for periods of active therapy or when relapse is suspected, not for routine surveillance. Waiting as long as every 2 years risks missing an early relapse. So, testing every 3-6 months is the typical approach for ongoing MRD monitoring.
