What is a TB Test (QuantiFERON-TB Gold)? A TB Test, specifically the QuantiFERON-TB Gold test, is a blood test used to detect latent or active tuberculosis (TB) infections. Also known as an Interferon-Gamma Release Assay (IGRA), this test measures your immune system's response to TB ...
Blood was collected for QFT-GIT assays [24] and Human Immunodeficiency Virus (HIV) antibody testing using the Determine™ (Abbot Laboratories, Illinois, USA) HIV 1/2 rapid test. The tubes for the QFT-GIT assay were incubated on site with a portable incubator. HIV testing was performed upon...
Sputum culture result was used as a gold standard. The specificity of the test was evaluated both in patients and in 55 tuberculin skin test (TST) negative healthy subjects. Results Out of the 140 study participants, 37 (26.4%) were positive for active PTB by culture. Out of the 37 ...
HIV-1 co-infection however has been shown to result in a reduced sensitivity of both IGRA platforms for tuberculosis [5, 6]. Boosting of inter- feron gamma release from circulating blood cells following TST has been observed within 3 days of administration [7]. This can result in conversion...
In 2015 a new QuantiFERON test has been introduced: the QuantiFERON®-TB Gold Plus (QFT-Plus) which will replace the currently used QuantiFERON-TB Gold in Tube (QFT-GIT). For this new test the peptide TB7.7 is removed and it contains an extra antigen tube (TB2) compared to its pred...

Stratifying the active TB patients according the microbiological status, we found that TB therapy significantly decreased IFN-γ response to antigen present in QFT-Plus test in patients with clinical diagnosis compared to those with a microbiological diagnosis. In conclusions, we demonstrated that TB ...
