A non-ischaemic cause of elevated troponin.
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.
