|What does viral load measure?
Mar 1, 2001
I phoned the lab where the viral load is measured and they told me they really don't know what they are measuring. I have read viral load measures ALL virus dead or alive, which means viral particles that don't have an affect on the body will be amplified as well, giving a false reading. No wonder the FDA hasn't approved viral load as a diagnostic tool. Mike

You are correct, viral load measures all viral particles that contain HIV RNA. The test cannot distinguish between infectious and noninfectious particles. However, the test has been validated in numerous studies for prognosis and treatment response.
