Does An IGRA Test Differentiate Active TB From Treated Infection? - Tuberculosis Disease Guide

Описание: Does An IGRA Test Differentiate Active TB From Treated Infection? Have you ever wondered how doctors determine if someone has a current tuberculosis infection or if they have simply been exposed in the past? In this informative video, we'll explain the purpose and limitations of the IGRA (Interferon-Gamma Release Assay) test. We'll start by describing what the IGRA test measures and how it works by detecting immune responses to TB proteins. You'll learn why a positive IGRA result indicates previous exposure to TB bacteria but does not necessarily mean active disease is present. We’ll also discuss how the immune system’s response can remain positive long after infection has been cleared or treated, and why this makes the test unsuitable for confirming active tuberculosis. Additionally, we'll cover the importance of other diagnostic tools like chest X-rays, sputum tests, and molecular diagnostics such as GeneXpert, which are used to identify active TB cases. If you or a loved one are undergoing testing for TB, understanding the role and limitations of the IGRA test can help clarify the diagnostic process.
