Testing for TB often starts with a purified protein derivative or PPD intradermal skin test, sometimes known as a tuberculin skin test, Mantoux test or simply TB test.

为检测TB的存在，我们通常从纯蛋白衍生物（PPD）皮内试验开始，也称为结核菌素试验、芒图试验，或就简称为TB皮试。

As an alternative to tuberculin skin test, there are also interferon gamma release assays or IGRAs which look for evidence in the blood of previous exposure to TB proteins.

作为结核菌素试验的替代性试验，γ-干扰素体外释放试验分析技术（IGRA）是寻找在血液中曾经接触过TB蛋白的证据。
