Breakthrough in HIV Testing: Saliva-Based Trial Shows 90%+ Accuracy in Ethiopia

A groundbreaking clinical trial in Ethiopia has demonstrated that saliva-based HIV testing could transform access to vital healthcare diagnostics, particularly in regions with limited medical infrastructure. Salignostics, a diagnostics company specializing in saliva-based testing, reported sensitivity exceeding 90% and specificity above 98% in their November 2024 trial, which evaluated 100 participants.

The significance of this development extends beyond the impressive accuracy rates. As the global HIV diagnostics market is projected to grow from $3.88 billion in 2021 to over $7 billion by 2034, innovations in testing methodology could substantially impact healthcare accessibility worldwide. The non-invasive nature of saliva testing eliminates the need for blood draws and specialized equipment, potentially reducing both costs and barriers to testing in resource-limited settings.

This advancement comes at a crucial time when healthcare systems worldwide are seeking more efficient and accessible diagnostic solutions. The ability to conduct HIV testing without traditional medical infrastructure could significantly increase testing rates in underserved communities, leading to earlier detection and treatment of HIV cases. The test's potential for use in homes, clinics, and community health settings could democratize access to HIV testing while maintaining high accuracy standards.

The success of this trial builds upon Salignostics' established track record in saliva-based diagnostics, including their Salistick pregnancy test which has sold over 500,000 units across markets including the UK and Israel. The company's expanding diagnostic portfolio, which includes applications for oral cancer and respiratory conditions, suggests broader implications for the future of medical testing beyond HIV diagnosis.
