About the TB Quantiferon Gold (IGRA) Test

QuantiFERON-TB Gold (QFT) is a simple blood test that aids in the detection of Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB). QFT is an interferon-gamma (IFN-γ) release assay, commonly known as an IGRA, and is a modern alternative to the tuberculin skin test (TST, PPD or Mantoux). Unlike the TST, QFT is a controlled laboratory test that requires only one patient visit and is unaffected by previous Bacille Calmette-Guerin (BCG) vaccination.

QFT is highly specific and sensitive: a positive result is strongly predictive of true infection with M. tuberculosis. However, like the TST and other IGRAs, QFT cannot distinguish between active tuberculosis disease and latent tuberculosis infection, and is intended for use with risk assessment, radiography, and other medical and diagnostic evaluations.

Like any diagnostic aid, QFT cannot replace clinical judgement.

Understanding TB

Tuberculosis (TB) is an airborne, highly contagious, infectious disease caused by Mycobacterium tuberculosis (MTB). Most frequently, TB affects the lungs, however, it can also cause disease in any part of the body, such as the lymph nodes, bones, brain, organs and eyes. TB is a serious disease that kills about 1.4 million people each year worldwide.

TB infection begins without symptoms before becoming active. This inactive carrier state is called latent TB infection (LTBI) and can persist for weeks, months or years before developing into active contagious disease. Although LTBI is not contagious, there is a ~10% average lifetime risk of it becoming active.

Active TB is a disease state of uncontrolled MTB growth which occurs when TB bacteria are able to overcome a person’s immune system and symptoms appear. Symptoms of active TB include chronic cough, fever, unexplained weight loss and, if severe, night sweats and even coughing up blood. A person who has active pulmonary TB is contagious.
