A viral load test is the most sensitive test to check whether a combination is still working.
After any treatment change, viral load should be checked every 2-4 weeks until it becomes undetectable.
Once viral load is undetectable you should be monitored with a viral load test every 3—4 months.
For more information on viral load see:
