The results demonstrated from the study indicated that QFT had a predictive value for developing TB disease of 15%, more than 6 times greater than the 2.3% for the TST.
The adoption of QFT will enable health authorities to confidently focus on individuals who are truly at risk of developing active TB, reducing the costs and risks associated with preventative treatment, and effectively reducing the overall number of cases of tuberculosis disease.
