Macrotroponin in the COVID-19 Era: An Under-Recognised Cause of Persistent Troponin Elevation

Abstract

Troponin is an important diagnostic tool, however, as the assay sensitivity and frequency of testing has increased in the COVID-19 era, a new cohort of patients with persistently elevated troponin has emerged. Interfering antibodies should be considered in patients with persistent and stable troponin elevation, where there is no ongoing cause.
