QuantiFERON-TB Gold (QFT) test

Those with positive results will proceed to sputum Xpert MTB/RIF, physical examination and chest CT scan, as well as sputum culture if necessary to distinguish latent TB infection (LTBI) from ATB. X-ray scan is conditional on age above 15 years with a positive QuantiFERON-TB Gold (QFT) test result.
