The rapid commercialised ICT Tuberculosis test has been tested in Madagascar for the diagnosis of smear-positive pulmonary (SM+) and extra-pulmonary tuberculosis (EPT), using microscopy, culture and histopathology as reference tests. Specificity was 83.3% and sensitivity 68.2% for SM+ patients and 65.2% for EPT patients. With a prevalence of 22.2% for SM+ patients and 52.4% for confirmed EPT among consulting patients in the National Reference Laboratory, the ICT Tuberculosis assay was not sufficiently predictive for application in the tuberculosis control programme.
