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
