How Does Interferon-Gamma Release Assay Test For TB? Curious about how healthcare professionals detect tuberculosis infection? In this informative video, we'll explain the process behind the Interferon-Gamma Release Assay (IGRA), a blood test used to identify if your immune system has ever encountered TB bacteria. We'll start by describing what the IGRA measures and how it works, focusing on the immune response involving T-lymphocytes and specific TB proteins. You'll learn about the different types of IGRA tests, such as QuantiFERON-TB Gold Plus and T-SPOT.TB, and how they analyze interferon-gamma levels or T cell activity to provide accurate results. We’ll cover the steps involved from drawing blood to incubation and testing, including how controls ensure the test's reliability. Additionally, we'll discuss what a positive result indicates and why further testing might be necessary to determine if the infection is active or latent. This test is especially helpful because it is not affected by prior BCG vaccination and requires only one visit. However, it does have limitations, including possible indeterminate results in immunocompromised individuals. Whether you're a patient, healthcare professional, or simply interested in TB prevention, understanding the IGRA test is essential.
