Interferon-Gamma Release Assays (IGRAs)

Interferon-Gamma Release Assays (IGRAs) are whole-blood tests that can aid in diagnosing Mycobacterium tuberculosis infection. They do not help differentiate latent tuberculosis infection (LTBI) from tuberculosis disease. Two IGRAs that have been approved by the U.S. Food and Drug Administration (FDA) are commercially available in the U.S:

  • QuantiFERON®-TB Gold In-Tube test (QFT-GIT); (本診所提供該項檢驗)
  • T-SPOT®.TB test (T-Spot)
