Tuberculosis (TB) remains a major threat to global health. The recently launched Global Plan to Stop Tuberculosis 2006-2015 highlights the need for accurate, simple and low-cost diagnostic tests for the detection of TB infection. For the first time in decades, new diagnostic tools have emerged that may facilitate this goal. The discovery of Mycobacterium tuberculosis-specific immunodominant antigens has led to the development of interferon gamma-release assays that have been shown to have high sensitivity and specificity for TB disease. This review focuses on the QuantiFERON-TB Gold tests and addresses the potential strengths and limitations of the current assays, summarizes the available evidence for their use and identifies areas of future research and development. Although representing an advance in TB diagnostics, with the potential to have a significant impact on global TB control, many issues remain unanswered. The cost of the tests and laboratory requirements may limit their use in developing countries. Most importantly, additional studies are needed in TB-endemic regions, particularly in high-risk persons such as children and individuals who are also co-infected with HIV.
