Understanding Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) in Bangalore
What is Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) in Bangalore?
Available at an affordable price in Bangalore with Tata 1mg labs, the Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) is a fourth generation assay that helps detect either a latent tuberculosis infection (LTBI) or an active tuberculosis (TB) disease. This test is suggested if you have symptoms of TB, such as persistent cough, fever, and sudden weight loss. It is particularly valuable for individuals who have had recent exposure to TB, healthcare workers, and those with a higher risk of TB infection.
The Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) test, also called QuantiFERON-TB Gold Plus (QFT Plus), is a modern alternative to the tuberculin skin test (TST). It assesses the specific immune response to TB, providing a more specific and sensitive analysis than the TST. A Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) test may be helpful for individuals who have been in close contact with someone with active TB, those with a history of travel to or residence in TB-endemic regions, and individuals with a weakened immune system. It is also used for healthcare workers, as well as in TB screening programs. QFT Plus is an indirect test for M. tuberculosis infection, but is more specific than TST and is unaffected by previous BCG vaccination. It provides doctors with an accurate, reliable and efficient assay for aiding the diagnosis of TB infection.
QFT-Plus is the newest and fourth version of the Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) test. It has new special antigen properties that work better to activate two types of immune cells, called CD4 and CD8 T-cells. This helps the test give a clearer and more complete view of how the body’s immune system is responding.
No fasting is required for this test. You can eat and drink normally as per your routine.
What does Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) measure?
The Quantiferon®-TB Gold Plus (Interferon Gamma Release Assay) test measures the immune system’s response to the bacteria that cause tuberculosis (TB). It measures two important types of immune cells T cells—CD4 and CD8 in response to tuberculosis (TB) bacteria. Both these cells play key roles in fighting infections. When a person’s immune system encounters TB bacteria, CD4 T-cells help coordinate and regulate other immune cells, while CD8 T-cells can directly kill infected cells. The test is tailored to activate both CD4 and CD8 T-cells. If these cells recognize the TB proteins, they release a signal called interferon-gamma (IFN-γ); hence the name IGRA (Interferon gamma release assay). By measuring this signal or stimulation from both CD4 and CD8 cells, the test gives a more complete picture of the body’s immune response to TB. This helps doctors better detect both active and latent TB infections, improving the accuracy and reliability of the test.
