Quantiferon TB Gold Info & Test Locations

What is a Quantiferon TB Gold Test?

The QuantiFERON-TB Gold test is a simple blood test that is designed to detect the presence of Mycobacterium tuberculosis, the bacteria which causes tuberculosis (TB).

TB is a highly infectious and potentially fatal disease that is spread through the air when an infected individual coughs or sneezes. It is responsible for more deaths annually than any other infectious disease - including HIV / AIDS. TB usually affects the lungs, but can also affect the brain, the central nervous system, the kidneys, the urinary tract and other organs.  It is possible to be infected and yet show no symptoms of having TB.

Some symptoms of Tuberculosis are:

  • Coughing that lasts three or more weeks
  • Coughing up blood
  • Chest pain, or pain with breathing or coughing
  • Fatigue or weakness
  • Fever, chills
  • Night sweats
  • Loss of appetite
  • Weight loss (unintentional)

How is the Quantiferon TB Gold Test Different from Standard Tuberculosis Skin Tests?

First approved by the U.S. Food and Drug Adminstration (FDA) in 2005, the QuantiFERON-TB Gold test offers a more accurate assessment of one’s exposure to TB than the common tuberculin skin test - which is now considered to be an outdated method for diagnosing the presence of TB.

Unlike tuberculin skin tests (TSTs), which require the patient to return within 48-72 hours to have their test results read, QuantiFERON-TB Gold test results can be available in less than 24 hours after testing and do not require a second patient visit.

Who should get a Quantiferon TB Gold Test?

The Quantiferon TB Gold test is recommended for all health care workers as well as anyone who works in a high-risk setting such as a correctional facility, long-term care facility, nursing home or homeless shelter, as well as anyone who has been exposed to a person who has TB.

TB tests are often required by employers, their schools and military agencies as a condition for obtaining clearance.

People who use drugs, have low immune systems or are HIV positive are more prone to contracting TB and should also get tested.
