Introduction. We reevaluated the usefulness of a whole-blood interferon-γ enzyme-linked
immunosorbent assay (QuantiFERON TB-2G [QFT-TB]; Cellestis) in obtaining a differential …

OBJECTIVE: To evaluate the clinical usefulness of the QuantiFERON® TB-2G (QFT-2G) test
in patients with non-tuberculous mycobacterial (NTM) disease without a previous history of …

We evaluated the usefulness of interferon-γ release assays (IGRAs) in the diagnosis of
active tuberculosis (TB) in routine clinical practice. We retrospectively assessed the …

Objective We prospectively evaluated the usefulness of the QuantiFERON TB-2G (QFT-2G)
compared to that of tuberculin skin test (TST) as a supportive method of diagnosing …

The usefulness of the tuberculin skin test (TST) and the QuantiFERON TB-2G (QFT-TB) test
were compared in immunocompromised patients. The subjects consisted of 252 …

OBJECTIVES: To compare the sensitivity and the specificity of the QuantiFERON®-TB Gold
(QFT-G) and QuantiFERON®-TB Gold In Tube (QFT-GIT) diagnostic tests for Mycobacterium …

In our study we evaluated the Quantiferon-TB Gold (QFT-G) test and compared it with
tuberculin skin test (TST) positivity in 44 pulmonary and 21 extrapulmonary tuberculosis …

Objective To evaluate transitional changes in QuantiFERON TB-2G (QFT-2G) test results in
the serial testing on the same patients and to reevaluate the optimal threshold of positive …

Rationale: Interferon (IFN)-γ blood tests may improve the current level of diagnostic accuracy
for tuberculosis infection. The QuantiFERON-TB Gold (QFT-Gold) has been used in selected …

To assess the performance of QuantiFERON®-TB Gold in-Tube (QFT-GIT; Cellestis,
