Data for: "The utility of repeat Xpert MTB/RIF testing to diagnose tuberculosis in HIV-positive adults with initial negative result"

Further evaluation of those who are HIV-positive and Xpert-negative comprises clinical reassessment, chest radiograph (if available), sputum for mycobacterial culture, and treatment with antibiotic if clinically indicated. The aim of our study was to describe the diagnostic yield from an immediate repeat sputum tested with Xpert, compared to sequential further investigation guided by South African recommendations , amongst HIV-positive adults in South Africa being investigated for TB whose initial sputum Xpert result is negative.

It was a sub-study of “Xpert for people attending HIV/AIDS care: test or review?” (XPHACTOR), a prospective cohort study evaluating a risk-based algorithm to prioritise Xpert testing amongst adults attending for routine HIV care in South Africa. This dataset contains data for 227 adults attending for routine HIV care who have an initial negative sputum Xpert result. It includes basic demographics, TB diagnoses, mycobacteriology and chest radiograph results.
