The Effect of HIV on the Association of Hyperglycaemia and Active Tuberculosis in Zambia, a Case-Control Study.

Objectives: To determine if HIV modifies the association between hyperglycaemia and active tuberculosis in Lusaka, Zambia.

Methods: A case-control study among newly-diagnosed adult tuberculosis cases and population controls in three areas of Lusaka. Hyperglycaemia is determined by random blood glucose (RBG) concentration measured at the time of recruitment; active tuberculosis disease by clinical diagnosis, and HIV status by serological result.

Sensitivity, specificity, and reproducibility of the Capilia TB-Neo assay.

The performance of the Capilia TB-Neo assay, a new-generation assay, was assessed by determining its sensitivity, specificity, reproducibility, and cross-reaction with contaminating organisms. The sensitivity and specificity were 99.2 and 96.
