Tuberculosis Diagnostics Strengthened by Molecular Detection, Rapid Screening Platforms, and Global Eradication
Tuberculosis remains a major infectious-disease challenge worldwide, prompting continuous innovation in diagnostic technology to support early detection, treatment monitoring, and global elimination efforts.
Traditional sputum-microscopy has largely transitioned toward rapid molecular diagnostic platforms, including nucleic-acid amplification testing, cartridge-based systems, and automated PCR devices capable of rapid Mycobacterium tuberculosis detection and rifampicin-resistance screening. Blood-based interferon-gamma release assays and advanced chest-imaging techniques complement frontline testing.
Point-of-care molecular tests and portable digital-radiography units expand access in resource-limited settings, while genomic sequencing enhances outbreak surveillance and drug-resistance mapping. Digital adherence tools and AI-assisted radiography analysis improve case detection among high-risk groups. Despite progress, diagnostic gaps persist due to access disparities, specimen-collection challenges, and latent-TB detection limitations. Scaling community screening, laboratory-network strengthening, and treatment-linkage strategies remains essential for achieving global TB-control milestones.
As research accelerates, future diagnostics may incorporate breath tests, host-response biomarkers, and handheld sequencing devices. Integration with digital platforms and real-time epidemiology networks will continue strengthening programmatic TB-care systems across countries and public-health infrastructures.
