US College Students Needing TB Testing Now Have the Benefit of QFT(TM)

Studies have shown that QFT is more accurate than the TST as it is not affected by BCG vaccination exposure to non-tuberculous mycobacteria. Greater accuracy means universities have to spend less money and time during the screening process. It streamlines the admission process and provides easier test administration for both universities and students as only one medical consultation is required; results are objective and can be available within 24 hours. Most importantly, treatment is dispensed to individuals truly infected with TB.

Each year US universities/colleges host approximately 500,000 international students. Many of these students come from high TB incidence areas withinAsia,Africa,Eastern Europe and Central andSouth America. The ACHA guidelines build on those issued by the Centers for Disease Control and Prevention (CDC) which state that QFT "can be used in all circumstances in which the TST is currently used" The ACHA recommends screening all incoming students, but particularly targeting those at increased risk for TB, which includes students from countries with a high incidence of TB disease (greater than or equal to 20 cases / 100,000 population). These students should be tested for latent TB infection (with either QFT or the TST), to reduce the risk of developing active TB disease. Additionally the ACHA guidelines recommend that health profession students, whether incoming or continuing, should be tested annually.

QFT is being used by a growing number of US colleges and universities including the University of Tennessee Health Science Center which published the first report of a college TB control program utilizing QFT (Vesser et al 2007). The report showed that QFT can be successfully implemented and is well accepted as an addition to a campus-wide TB surveillance program.

About QuantiFERON(R)-TB Gold (QFT(TM)):

QFT -- a simple blood test -- is the first major advance in TB diagnosis since the introduction of the tuberculin skin test (TST) over 100 years ago. The QFT test is based on measurement of a cell-mediated immune response in TB- infected individuals. The T-cells of these individuals are sensitized to TB, and respond to stimulation with peptides simulating those expressed by the TB causing bacteria, secreting a cytokine called interferon-gamma. QFT accurately measures the interferon-gamma response in a sensitive enzyme assay. QFT is unaffected by previous BCG vaccination and most other mycobacteria. Unlike the TST, it requires only one patient visit, is a controlled laboratory test, and provides an objective, reproducible result that is not subject to interpretation based on a patient's relative risk factors for TB exposure.
