Agreement between QFT positivity and TST (≥10mm) positivity, by age and BCG vaccination scar status
The positivity of QuantiFERON interferon-γ release assay (QFT) and tuberculin skin test (TST; ≥10 mm) results are shown in every age group by the status of BCG scar. TST was affected by BCG vaccination especially among those who might have had a booster BCG vaccination.
