The final piece of the puzzle is affordability, that is we need to know whether these oil-rich countries can afford QFT-TB testing for these workers?The comment was in reference to the growing demand for QFT in the Middle East.
What people need to understand is that it is the TST that is the more costly eg in the very latest study from France
Our objective was to evaluate the cost-effectiveness of replacing TST with QFT or TST+QFT (i.e., QFT performed only when TST-positive) in the diagnosis of LTBI in close contacts of tuberculosis (TB) in France, where patients are BCG-vaccinated
..In conclusion, our analysis provides evidence that using QFT to diagnose LTBI is less costly and more efficient than using the TST. QFT was more expensive but also more efficient and more cost-effective than TST+QFT.
