The QuantiFERON-TB Gold Plus (QFT-Plus) test is a cutting-edge diagnostic tool for tuberculosis (TB) infection. It utilizes advanced technology to accurately detect both latent TB infection and active TB disease. This blood-based test is highly precise, providing reliable results within a short timeframe. It offers an efficient and convenient alternative to traditional skin tests, offering greater sensitivity and specificity. The QFT-Plus test is an invaluable tool for healthcare professionals and public health agencies in their efforts to identify and control TB spread in individuals and communities.

QuantiFERON-TB Gold Plus is a blood test that can help detect Mycobacterium tuberculosis, the bacteria that causes tuberculosis (TB). It is a modern alternative to the tuberculin skin test (TST).
QFT-Plus is a blood test that can be used in place of the tuberculin skin test (TST) for people who are at risk of tuberculosis (TB). This includes people who:
QFT-Plus can also be used to confirm a positive TST result. It is important to note that QFT-Plus can be used in people who have been previously vaccinated against TB.
Typically a QFT-Plus test does not require any special test preparations. However, your doctor may advise you to discontinue certain medications or supplements before the test and will inform you accordingly.
Exactly, your understanding is correct. Latent tuberculosis infection (LTBI) means that a person has been infected with the bacteria that cause tuberculosis, but the bacteria are in an inactive state. As you mentioned, most people with latent TB do not feel sick and do not have symptoms. However, the bacteria can become active, leading to the development of active TB disease. Individuals with compromised immune systems are at higher risk of progressing from latent TB to active TB.
Testing for latent TB and, if necessary, providing preventive treatment is crucial to reduce the risk of active TB disease. It's an essential component of tuberculosis control programs to prevent the spread of the disease and protect public health.
The QFT-Plus can replace the skin test and is suitable for individuals who:
Additionally, individuals who work with, or are part of groups at high risk of infection, such as IV drug users, or those in confined populations like hospitalized patients, prisoners, and residents of nursing homes, can also use this test.
The QFT-Plus is effective in people who have been previously vaccinated against TB and can also serve to confirm a positive skin test result.
The QFT-Plus test assists your healthcare provider in assessing whether you have TB. It will yield one of two outcomes:
In some cases, the results may be inconclusive. If this occurs, your healthcare provider might recommend a repeat test for further clarification.
