Discussion Regarding Tuberculin Skin Tests and Interferon-gamma Release Assays for the Differential Diagnosis of Pulmonary Tuberculosis

摘要

The Authors Replies We thank Dr. Wiwanitkit for the comments on our original article. We compared the usefulness of tuberculin skin tests (TSTs) and three interferon-gamma release assays (IGRAs) (QuantiFERON-TB Gold (QFT-2 G), QuantiFERON-TB Gold In-Tube (QFT-3 G) and T-SPOT.TB) in order to investigate which method is the most useful clinically as a supportive method for diagnosing pulmonary tuberculosis (TB). Subsequently, the present study demonstrated the three IGRAs to be significantly more useful than TSTs; however, no significant differences among the three IGRA tests were observed.
