Global Latent TB Testing Market size and share is currently valued at USD 576.68 million in 2024 and is anticipated to generate an estimated revenue of USD 1,005.69 million by 2034, according to the latest study by Polaris Market Research. Besides, the report notes that the market exhibits a robust 5.7% Compound Annual Growth Rate (CAGR) over the forecasted timeframe, 2025 - 2034
The latent TB testing market is experiencing steady growth as healthcare systems worldwide intensify efforts to identify and manage latent tuberculosis (TB) infections. Latent TB infection occurs when an individual is infected with Mycobacterium tuberculosis but does not show active disease symptoms, yet remains at risk of developing active TB in the future. Early detection through accurate and reliable testing is critical for disease control, public health management, and the global effort to eliminate tuberculosis. The increasing prevalence of TB, government initiatives, and advances in diagnostic technologies are driving demand for latent TB testing solutions globally.
Market Summary
Latent TB testing involves the detection of tuberculosis bacteria in individuals who do not exhibit active TB symptoms. These tests play a crucial role in preventing the progression of latent infections into active TB, which is highly contagious and a major public health concern. Testing solutions include the traditional Tuberculin Skin Test (TST) and modern Interferon-Gamma Release Assays (IGRAs), which offer higher specificity and reduced cross-reactivity with Bacillus Calmette-Guérin (BCG) vaccination.
The latent TB diagnostics industry is expanding due to increased awareness of TB prevention, rising funding for global TB control programs, and the adoption of advanced diagnostic techniques in healthcare facilities. With tuberculosis remaining a leading infectious disease worldwide, proactive latent TB testing is recognized as a crucial preventive strategy, particularly among high-risk populations such as immunocompromised patients, healthcare workers, and individuals living in high TB prevalence regions.
Healthcare providers are increasingly integrating latent TB testing into routine screenings for at-risk groups. Advancements in point-of-care testing, automated systems, and digital health platforms are enhancing accessibility, reducing turnaround times, and improving overall efficiency in TB control programs.
Key Market Trends
One prominent trend in the latent TB testing industry is the adoption of interferon-gamma release assays (IGRAs) as a preferred diagnostic tool. IGRAs, including QuantiFERON-TB Gold and T-SPOT.TB tests, provide higher accuracy, reduce false positives associated with prior BCG vaccination, and require fewer patient visits compared to traditional skin tests. This trend reflects the ongoing shift toward more reliable, rapid, and patient-friendly diagnostic methods.
Another notable trend is the integration of digital and point-of-care diagnostic technologies. Portable devices, automated testing systems, and digital reporting platforms enable healthcare providers to offer quick and accurate latent TB testing, particularly in resource-limited settings. This digital integration also supports data management, epidemiological tracking, and compliance with public health initiatives.
The rising emphasis on preventive healthcare and public health programs is also driving market growth. Government initiatives, global health campaigns, and WHO-led strategies aimed at TB eradication are promoting widespread latent TB testing, particularly in high-risk populations. Awareness campaigns targeting both healthcare providers and the general public are contributing to increased screening and early detection.
Additionally, the development of multiplex diagnostic solutions that combine latent TB testing with other infectious disease markers is gaining traction. These integrated solutions improve efficiency, reduce healthcare costs, and streamline the testing process for patients and healthcare providers alike.

Opportunities in the Latent TB Testing Market
The latent TB testing market offers significant growth opportunities driven by increasing healthcare access, technological advancements, and heightened public health focus. One of the most prominent opportunities lies in the expansion of testing programs in emerging markets. Countries with high TB burden, including India, Indonesia, and South Africa, are increasingly implementing nationwide screening initiatives, creating substantial demand for advanced diagnostic solutions.
Another growth avenue is the development of point-of-care and home-based testing kits. Portable, easy-to-use diagnostic tools can enable timely detection of latent TB infections in remote or underserved regions, improving early intervention and reducing disease transmission.
The rising prevalence of immunocompromised individuals, including patients with HIV/AIDS, organ transplant recipients, and those receiving immunosuppressive therapies, presents further opportunities. Targeted screening programs for these high-risk populations can enhance early detection and improve patient outcomes while supporting public health objectives.
The integration of digital health platforms and AI-based analytics also represents a significant opportunity. By leveraging digital tools to manage test results, monitor trends, and predict high-risk populations, healthcare providers and public health organizations can optimize resource allocation and improve latent TB management strategies.
Collaborations between diagnostic companies, healthcare providers, and government agencies provide additional opportunities to expand testing coverage, enhance awareness, and improve access to latent TB diagnostics.
