QuantiFERON-TB Gold In-Tube test®IFN-γThe QuantiFERON-TB Gold In-Tube test has excellent specificity for Mycobacterium tuberculosis . However, diagnosis of miliary tuberculosis remains challenging, and the interpretation of QuantiFERON results in immunocompromised individuals has not been fully ...
prior BCG vaccination or exposure to non-tuberculosis mycobacteria. However, no test is completely foolproof. Factors like recent TB exposure, immune system status, and laboratory procedures can influence the results. Always discuss your results with your healthcare provider for accurate interpretation. ...
TheQuantiFERONTB-Gold test (QFTG: Qiagen, Germantown, Maryland, USA) is a blood test designed to specifically detect TB. One advantage over the Mantoux test is the fact that the QuantiFERON blood test does not require a return office visit for interpretation[74]. The blood test quantifies...
We abstracted reasons for testing, reported risk(s) for LTBI, ancillary LTBI testing, and clinical interpretation of the QFT-GIT (LTBI or not LTBI). These variables were then correlated to the quantitative result. Results: 145 patients were identified (54% female, median age 44). Median ...
tuberculosis infection is not recommended in this resource-constrained setting as test results showed substantial concordance and TST positivity was not affected by previous BCG vaccination. The QFT-GIT had a higher sensitivity than the TST for the detection of TB disease. However, the value of the...

Using the manufacturer recommended cut-off value; we found sensitivity of 64.5% and specificity of 36.8% of the test. The sensitivity of the test observed in the present study is much lower than sensitivity reported from TB endemic areas using the same test [9, 29]. The discrepancy between ...
The quantitative values of the IFN-γ response were reported to be higher among active patients with TB than among patient with LTBI using QuantiFERON-TB Gold (QFT TB-2G) [18] and QFT-GIT [19]; however, contradictory results were reported using QFT-Plus [11,12]. In the present study,...
QuantiFERON-TB Gold (p=0.0010). INTERPRETATION: T-SPOT.TB and QuantiFERON-TB Gold have higher specificity than the tuberculin skin test. Rates of indeterminate and positive results, however, differ between the blood tests, suggesting that they might provide different results in routine clinical ...
What’s new (version 4): Q9: Does vaccination affect a QFT-TB Gold Plus Tesult? Question 1. What is QuantiFERON®-TB Gold Plus? Question 2. How does QFT-Plus test work? Question 3. What are the advantages of QuantiFERON-TB Gold Plus over TST? Question 4. How do you interpret...
