A 27-year-old woman with chest pain was admitted for elevated troponin levels. Troponin remained mildly elevated upon repeat testing, and a review of the medical record revealed that she had had an elevated troponin level in the past. She had a cardiac catheterisation that revealed angiographically normal coronary arteries. Repeat troponin testing with and without ethylene glycol revealed a negative troponin level after addition of ethylene glycol, suggesting antibodies were interfering with the assay.
一名27岁胸痛女性因肌钙蛋白水平升高入院。复查时肌钙蛋白仍轻度升高，查阅病历发现她过去肌钙蛋白水平也曾升高。她接受了心脏导管检查，血管造影显示冠状动脉正常。在添加和不添加乙二醇的情况下重复检测肌钙蛋白，添加乙二醇后肌钙蛋白水平呈阴性，提示抗体干扰了检测。
