Frequently Asked Questions (FAQs)

Interferon gamma release assay (IGRA) test is a blood test that detects the presence of interferon-gamma, a type of protein that the body produces in response to tuberculosis bacteria. The IGRA test is becoming increasingly popular as an alternative to traditional skin tests for TB because it's more accurate and reliable


One key significance of IGRA tests is their ability to produce results within 24 hours, which makes it easier for healthcare practitioners to initiate appropriate treatment plans promptly. Additionally, since these tests are not affected by prior BCG vaccination like the tuberculin skin test, they offer greater accuracy and reliability.


Well, the answer largely varies depending on the lab conducting the test and their testing procedures. However, most labs usually take between 24-72 hours to return IGRA test results.


The accuracy of IGRA has been extensively studied and tested across various populations worldwide. IGRA has a sensitivity rate of 80-98% and a specificity rate of 95-99%. This means that the likelihood of getting an accurate result from the test is very high.


One of the most significant benefits of IGRA is that it does not require sputum production or culture like traditional TB tests. This makes it more convenient and less invasive for patients while also reducing the risk of spreading TB in clinical settings.


In general, healthy individuals have levels ranging from 0-10 IU/mL using QuantiFERON®-TB Gold Plus or T-SPOT.


One of the significant functions of interferon-gamma is its ability to stimulate the production of antibodies against viruses, bacteria, parasites, and any other foreign invaders. This makes it an important tool in fighting infections.


Several factors can increase interferon-gamma levels, including infections, autoimmune disorders, and exposure to certain chemicals or allergens.
