Saliva test device market seen reaching $1.79 billion by 2030

The saliva test device market is projected to grow from $1.27 billion in 2026 to $1.79 billion by 2030, driven by infectious disease screening, home testing and new diagnostic technologies. North America led the market in 2025, while Asia-Pacific is expected to be the fastest-growing region.

Why it matters: - Saliva-based testing is becoming a bigger part of medical, forensic and home diagnostics because the samples are non-invasive and fast to collect. - Growing demand for easier disease detection and drug screening is pushing more investment into saliva test devices. - The market's forecast growth suggests broader adoption across clinics, forensic labs and at-home testing services.

What happened: - The Business Research Company published its Saliva Test Device Global Market Report 2026 – Market Size, Trends, And Forecast 2026-2035. - The report estimates the saliva test device market will rise from $1.16 billion in 2025 to $1.27 billion in 2026. - The report projects the market will reach $1.79 billion by 2030. - The report puts the market's CAGR at 9.5% for the historic period and 9.0% through 2030.

The details: - Saliva test devices detect substances or biomarkers in saliva samples. - The devices are used to diagnose infections, monitor drug use, assess hormone imbalances and identify diseases. - Historical growth has been supported by rising drug abuse, stronger demand for workplace drug screening, improved immunoassay technologies, growth in forensic laboratories and wider awareness of non-invasive diagnostics. - Future growth is expected to be driven by artificial intelligence and machine learning in saliva diagnostics, expansion of home healthcare testing, broader use of PCR-based saliva tests, more disease monitoring and new multiplex testing panels. - The report highlights non-invasive diagnostics, rapid at-home testing, multi-drug detection, personalized health tracking and expanded forensic use as key trends. - The market's growth is also linked to the rising incidence of infectious diseases worldwide. - Increased global travel has accelerated pathogen transmission across borders. - Saliva testing supports point-of-care and at-home testing because sample collection is simple and non-invasive. - Faster results can shorten diagnostic timelines and support earlier treatment management. - The UK Health Security Agency reported in February 2024 that tuberculosis cases in England increased to 4,850 in 2023 from 4,380 in 2022. - North America held the largest share of the saliva test device market in 2025. - Asia-Pacific is expected to be the fastest-growing market during the forecast period. - The report also covers South East Asia, Western Europe, Eastern Europe, South America, the Middle East and Africa. - The Business Research Company said its 2026 market reports now include market attractiveness scoring, TAM analysis, company scoring matrix graphics and tables, Excel-based forecasting dashboards, market hotspots infographics, key technology analysis and updated graphics and tables.

Between the lines: - The forecast points to a shift from niche diagnostic use toward broader routine screening and monitoring. - Infectious disease pressure is giving the category a clear practical use case, while AI and PCR adoption suggest the technology base is still evolving. - Regional momentum is likely to stay strongest where healthcare access, at-home testing and diagnostic innovation are expanding fastest.

What's next: - The report points to continued market expansion through 2030 as device makers push faster, more versatile saliva testing platforms. - Widening use in home healthcare and disease monitoring should keep non-invasive testing central to category growth. - More emphasis on multiplex testing and AI-enabled diagnostics could shape product development over the next several years.

The bottom line: - Saliva test devices are moving from convenience tools to a larger diagnostic category, with infectious disease screening and at-home testing driving the next leg of growth. - Download a free sample of the report - View the full market report
