Critical need for more viral load testing

New research has again confirmed the importance of viral load testing, which measures the amount of HI virus in the blood, to determine whether someone on antiretroviral (ARV) treatment is experiencing treatment failure and needs to be switched to a second-line drug regimen.

Regular viral load testing is standard practice in developed countries (an increased viral load indicates that a patient has developed resistance to one or more ARV drugs) but such tests are often unavailable in resource-limited settings because of their cost and a lack of laboratory capacity.
