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。

In other words, sometimes a person might have no allergic reaction on the skin test, but have a localized allergic reaction affecting the nasal cavity and eyes - that's low sensitivity.

换言之，一个在鼻子和眼睛局部存在着过敏性反应的患者在做皮肤点刺试验时可能出现假阴性的结果，这就是所谓的低敏感性。
