WHO Toolkit to Optimize HIV Testing Algorithms

A standardized HIV testing strategy and quality-assured products are critical for accurate diagnosis, while poorly chosen testing algorithms can lead to misdiagnosis. Verification of testing algorithms provides objective evidence, before widespread implementation, that a specific combination of products will accurately diagnose HIV infection, thus reducing the risk of misdiagnosis.

The toolkit aims to provide countries with the tools and content needed to effectively conduct a local verification assessment to update national HIV testing algorithms following WHO recommendations on HIV testing strategies.
