According to a new report published by SNS Insider, the latent Tuberculosis Infection Detection Market was valued at USD 1.65 billion in 2023 and is projected to reach USD 2.71 billion by 2032. The market is expected to grow at a steady CAGR of 5.72% during the forecast period of 2024–2032, driven by rising global awareness, increasing government initiatives for tuberculosis control, and advancements in diagnostic technologies.

Tuberculosis (TB), a major infectious disease, remains one of the top 10 causes of death worldwide. While active TB cases receive most of the attention, latent TB infections (LTBI) — where individuals are infected but asymptomatic — form a significant hidden reservoir. Nearly one-fourth of the global population is estimated to carry LTBI. Early detection and treatment of LTBI are crucial for breaking the chain of transmission, and this is where the detection market is playing an increasingly vital role.

Growing investments in healthcare infrastructure across developing economies, especially in high TB burden regions such as Asia-Pacific and Africa, are creating substantial opportunities for the LTBI detection market. Governments and global health agencies such as WHO and CDC are actively promoting LTBI screening in high-risk populations, including healthcare workers, immunocompromised individuals, and migrants from TB-endemic regions.

Furthermore, the development of more accurate and cost-effective diagnostic tools such as interferon-gamma release assays (IGRAs) and next-generation tuberculin skin tests (TSTs) is boosting market adoption. These tests offer higher specificity, better patient compliance, and faster turnaround times, which significantly improve early intervention outcomes. Integration of artificial intelligence and digital diagnostics is also emerging as a transformative trend in TB detection.

Market Segmentation and Regional Insights

The market is segmented based on test types (IGRA and TST), end-users (hospitals, clinics, diagnostics labs, and others), and regions. Among these, IGRAs are gaining momentum due to their higher accuracy, especially in BCG-vaccinated individuals. Hospitals and diagnostics labs remain the dominant end-users owing to robust healthcare setups and greater accessibility to advanced technologies.

Regionally, North America held the largest share of the latent tuberculosis infection detection market in 2023, thanks to strong awareness campaigns and extensive screening programs. However, Asia-Pacific is projected to grow at the fastest pace during the forecast period due to rising TB incidence, growing healthcare spending, and favorable government initiatives. India and China are expected to be key growth drivers in the region.

Key Players and Competitive Landscape

Leading companies in the LTBI detection market are actively focusing on R&D, strategic collaborations, and product innovation to strengthen their market position. Some of the prominent players include:

• QIAGEN N.V.

• Oxford Immunotec

• Abbott Laboratories

• F. Hoffmann-La Roche AG

• BioMérieux SA

• Thermo Fisher Scientific Inc.

• Siemens Healthineers

• Creative Diagnostics

• Hologic Inc.

These companies are investing in the development of portable, point-of-care diagnostic devices and expanding their presence in emerging markets through distribution partnerships and regulatory approvals.

Industry Trends and Future Outlook

The latent TB infection detection industry is witnessing a paradigm shift driven by digital health integration, precision medicine, and greater public-private partnerships. Mobile-based TB testing, AI-powered risk assessments, and wearable health trackers are being explored to improve accessibility in remote and underserved areas. Additionally, growing awareness around the risk of TB reactivation in immunosuppressed individuals is expanding the application base for LTBI screening.

As the world moves closer to the WHO’s End TB Strategy goals for 2035, early detection of latent TB will remain a cornerstone of global health policies. The rising emphasis on preventive healthcare and infectious disease surveillance is set to fuel demand for innovative diagnostic solutions in the coming years.
