The global latent tuberculosis (TB) testing market is projected to grow from USD 582.5 million in 2024 to USD 773.4 million by 2029, reflecting a compound annual growth rate (CAGR) of 5.8%. This growth is fueled by the increasing global prevalence of tuberculosis, the rising demand for early detection, and the expansion of preventive healthcare initiatives.
Traditional tuberculin skin tests (TSTs) face challenges such as false positives, particularly in populations vaccinated with Bacillus Calmette-Guérin (BCG). This limitation has accelerated the adoption of more precise diagnostic methods, particularly interferon-gamma release assays (IGRAs). Additionally, global TB elimination programs led by governments and public health organizations are intensifying demand for efficient latent TB testing solutions. Greater awareness among healthcare providers and at-risk populations, including immunocompromised individuals such as those living with HIV, is further driving the market. Increased financial and regulatory support is also making advanced diagnostics more widely accessible, contributing to sustained market expansion.

Market Growth Fueled by IGRA Advancements
The latent TB testing market is undergoing a significant transformation with the growing emphasis on IGRA technology. These tests offer superior accuracy and sensitivity compared to TSTs, particularly in BCG-vaccinated individuals. As global healthcare systems move towards precision diagnostics, the demand for IGRAs is increasing due to their enhanced specificity and the ability to deliver results in a single visit. Furthermore, automation and technological advancements in IGRA platforms are making these tests more scalable and accessible, particularly in high-burden and resource-limited regions. This technological shift is expected to drive market growth, encouraging new entrants and further investments in IGRA innovations.
Market Segmentation Insights
By test type, the latent TB testing market is segmented into tuberculin skin tests (TSTs) and interferon-gamma release assays (IGRAs). The IGRA segment is projected to witness the highest growth, driven by its greater accuracy, reduced incidence of false positives, and improved patient convenience by eliminating the need for follow-up visits. These advantages are particularly crucial in high-risk populations and high-burden regions, further boosting IGRA adoption.
By application, the market is categorized into household contacts with pulmonary TB, people living with HIV, and other applications. The fastest-growing segment is expected to be household contacts with pulmonary TB. Individuals in close proximity to active TB patients are at heightened risk of infection, making routine screening a priority for TB control programs. Government and international health organizations are increasingly investing in the screening and management of latent TB in high-risk groups, with advanced diagnostics such as IGRAs playing a critical role in detecting and preventing disease progression.
