Bovine tuberculosis remains a persistent threat to livestock health, food safety, and public health worldwide. With its insidious transmission dynamics and chronic presentation, early and accurate detection is imperative for effective disease control and eradication efforts. The traditional reliance on intradermal tuberculin tests, while foundational to historical eradication programs, presents limitations in sensitivity, specificity, and logistical efficiency. Evolving pathogen surveillance demands have underscored the necessity for a complementary portfolio of diagnostic modalities capable of addressing the dual objectives of rapid field screening and laboratory confirmation. These factors converge amid growing global concerns over zoonotic spillover and the economic impact of herd disruptions. It is within this context that stakeholders across government agencies, veterinary laboratories, and research institutions are intensifying efforts to refine diagnostic algorithms and integrate novel assay technologies into existing surveillance frameworks.

Scaling up diagnostic capacity requires a clear understanding of test performance characteristics across methods. The caudal fold test, extensively deployed in field settings, accounted for over 318,000 applications in Texas during FY2024 alone, illustrating its enduring role in herd-level screening despite challenges of false positives and variable sensitivity in certain cattle populations. Complementarily, cervical intradermal tests, including comparative and single-site formats, deliver nuanced specificity improvements but necessitate skilled administration and extended observation periods. In response, interferon-gamma release assays and enzyme-linked immunosorbent assays have gained traction by offering standardized laboratory platforms with enhanced reproducibility, while molecular approaches promise earlier pathogen detection at the nucleic acid level. By examining fundamental testing principles, stakeholders can align diagnostic strategies with programmatic goals, reducing both disease burden and operational costs.

Recent years have witnessed a paradigm shift in bovine tuberculosis diagnostics, driven by advancements in molecular assay design and automation. Whereas the conventional tuberculin skin tests have long been the cornerstone of surveillance programs, their moderate sensitivity and reliance on host immune response kinetics created gaps in early detection. In contrast, quantitative real-time polymerase chain reaction (qPCR) and isothermal amplification methods now achieve diagnostic sensitivities exceeding 70% and specificities above 96%, with some loop-mediated isothermal amplification protocols approaching 99% sensitivity and 99.8% specificity. These molecular platforms, often tailored to target insertion sequences like IS6110 or the RD4 gene, enable direct pathogen identification from lymph node or milk samples in a matter of hours, markedly reducing delay compared to culture-based confirmation.

Concurrently, laboratory infrastructure is evolving to support high-throughput testing and integrated data management. Cutting-edge extraction protocols optimized for fresh bovine tissue have yielded sample-to-result workflows under three hours, minimizing DNA degradation and cross-contamination risks.
