Viral load tests

Viral load is the most sensitive test to check whether a combination is still working.

Testing 2-4 weeks after any change in treatment will show whether the new drugs are working, repeating monthly until undetectable.

Once undetectable, monitor every 3-6 months, based on the CD4 count.
