A population-based retrospective cohort study in CMAJ reported that one in five pregnant individuals in Ontario did not receive timely syphilis screening during pregnancy. The findings highlight gaps in a preventive service that is critical to reducing congenital syphilis risk. The study examines adherence to screening timelines in real-world prenatal care and underscores how missed tests can create downstream outcomes. For biotech and diagnostics stakeholders, the data reinforces the importance of workflow integration and risk-based strategies to improve screening compliance.
