[Characteristics of a diagnostic method for tuberculosis infection based on whole blood interferon-gamma assay]. Background: Prevention of tuberculosis (TB) in the United States usually involves testing for latent tuberculosis infection (LTBI) with a tuberculin skin test (TST), followed by offering therapy to those who have a positive test result. Potential sources for variable immune responses include changing CD4 cell count, medications, stress, and infection. Ebola, COVID-19 and Africa: What we expected and what we got. |

Prognostic impact of preoperative FDG-PET positive lymph nodes in lung cancer. Among 100 adults who were BCG-vaccinated and had a positive TST result, 30 (30%) had a positive result using QFT-G. It is an indirect test for M. tuberculosis infection. Lin WC, Lin HH, Lee SS, Sy CL, Wu KS, Chen JK, Tsai HC, Chen YS.
Background: Of the 49 repeated QFT tests, 35 (71.4%) reverted to negative, 12 (24.5%) remained positive, and 2 (4.1%) were indeterminate. [Characteristics of a diagnostic method for tuberculosis infection based on whole blood interferon-gamma assay]. The main drawback of the TST is its poor specificity as previous bacillus Calmette–Guérin (BCG) vaccination and non-TB mycobacterial exposure can lead to false-positive results. These articles were read and analyzed. The CDC guidelines recommend IGRA testing for BCG-vaccinated individuals and those unlikely to return for TST readings [4].

Comparison of QuantiFERON-TB Gold test and tuberculin skin test for the identification of latent Mycobacterium tuberculosis infection in lupus patients. As with TSTs, IGRAs rely on functioning cell-mediated immunity and therefore have higher rates of failed tests in HIV-infected patients [11–13]. In our population of HIV-infected patients living in Denver, Colorado, positive QFT results reverted to negative in 80.5% of US-born patients at low risk for tuberculosis exposure.
