M. tuberculosis specific interferon-gamma tests have been established lately as an important additional instrument in the diagnosis of the latent tuberculosis infection (LTBI). In several studies these tests had a higher specificity compared to the tuberculin skin test (TST). In this report we describe the case of a woman without increased risk for LTBI and with discordant results for the interferon-gamma tests QuantiFERON-TB Gold In-Tube and T-SPOT.TB and for the TST. The findings suggest repeated false-positive results of the QuantiFERON-TB Gold In-Tube test.
结核分枝杆菌特异性干扰素-γ检测最近已成为诊断潜伏性结核感染（LTBI）的一项重要辅助手段。在多项研究中，这些检测的特异性高于结核菌素皮肤试验（TST）。在本报告中，我们描述了一名女性病例，该女性无LTBI风险增加因素，其QuantiFERON-TB Gold In-Tube检测、T-SPOT.TB检测及TST结果不一致。这些发现提示QuantiFERON-TB Gold In-Tube检测反复出现假阳性结果。
