What measurement is used to monitor response to HIV treatment?

Explanation:
Monitoring how well HIV treatment is working relies on measuring the amount of HIV RNA in the blood, called the RNA viral load. The goal of antiretroviral therapy is to suppress viral replication to undetectable levels, so regular viral load testing shows whether the therapy is effectively controlling the virus and whether adherence is adequate. A decreasing viral load that becomes undetectable indicates a good response and prognosis. CD4 count reflects immune system status and risk for opportunistic infections, but it changes more slowly and doesn’t reliably show how well the virus is being suppressed. IgG antibodies indicate prior exposure and immunity history, not current viral activity. CD8 counts aren’t used to monitor HIV treatment response.
