WHO develops guidelines for multiplex testing to improve integrated diagnostics

WHO is developing guidelines for multiplex testing to improve integrated diagnostics for HIV, viral hepatitis, and STIs. The guidelines will establish principles for using single tests to detect multiple infections simultaneously, aiming to enhance efficiency and expand testing coverage, especially in low- and middle-income countries. This marks the first WHO guideline specifically addressing multiplex testing, providing a framework for its application and future multi-disease testing approaches.
