Diagnostic Performance of Droplet Digital PCR for Pulmonary Tuberculosis and Pleurisy

A clinical study evaluating a droplet digital PCR (ddPCR) assay for tuberculosis diagnosis, involving 436 patients with suspected pulmonary tuberculosis or tuberculous pleurisy. The dataset, authored by Xichao Ou and last updated in April 2026, compares the ddPCR assay's sensitivity and specificity against Xpert MTB/RIF and culture methods.

Use Cases

• Benchmarking diagnostic sensitivity for paucibacillary tuberculosis based on the reported performance metrics.
• Developing models for Mycobacterium tuberculosis and non-tuberculous mycobacteria differentiation based on the dual-target design.
• Comparing molecular diagnostic methods (ddPCR vs. Xpert MTB/RIF) for pulmonary and pleural samples.
• Analyzing clinical performance trade-offs between sensitivity and specificity in tuberculosis testing.

Strengths

• Includes performance metrics for 436 patients, providing a substantial clinical sample size.
• Reports specific sensitivity (49.70% for PTB) and specificity (98.65% for Xpert) figures for method comparison.
• Enables differentiation between Mycobacterium tuberculosis and non-tuberculous mycobacteria via a dual-target design.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data is contained in a DOCX file, which may require extraction or conversion for analysis.
