The Evolution of STI Testing: A Catalyst for Modern Diagnostic Technologies
Laboratory-Based Testing: The High-Throughput Cornerstone Laboratory-based testing has long served as the cornerstone of STI diagnostics. Major clinical laboratories and global diagnostics companies dominate this space, leveraging advanced molecular and immunoassay platforms to deliver high-volume, high-accuracy results. Data on total annual STI tests remains limited, as typically only positive results are tracked. 3 However, centralized laboratories, including hospital and reference labs, remain the dominant mode of STI testing, representing approximately 58-62% of the global STI diagnostics market in 2024. 4 Despite advances in decentralized and POC testing, centralized laboratories remain essential, meeting the growing demand for high-throughput, clinically-validated diagnostics. Integrated with electronic medical records (EMRs) and public health databases, they enable efficient test-and- treat workflows and large-scale surveillance.
However, multi-day turnaround times and the need for in-person specimen collection can still limit accessibility and delay results. According to Mordor Intelligence , a small group of global diagnostics companies account for the majority of STI testing worldwide. The five leading firms—Siemens Healthineers, Abbott Laboratories,
