European Test Finder (ETF) is an innovative, free online platform designed to help individuals locate testing services for HIV, hepatitis B and C, and sexually transmitted infections (STIs) across the WHO European region. Launched in 2015 and further developed with support from the European Centre for Disease Prevention and Control (ECDC), ETF provides a user-friendly directory that connects users with the nearest testing facilities. The service was expanded in early 2022 to include essential treatment options for HIV, tuberculosis, and opioid substitution therapy, particularly to assist individuals affected by the war in Ukraine.

ETF's directory is curated through contributions from testing service providers who register and maintain their own profiles, ensuring information remains accurate and current. While ETF aims to encompass as many available services as possible, it encourages continuous engagement from providers to enhance the resource. The initiative is strengthened through collaborations with various organizations and community partners dedicated to promoting safe health practices and ensuring timely diagnosis and care for all users.
