In the Original Investigation titled “Efficacy of High-Sensitivity Troponin T in Identifying Very-Low-Risk Patients With Possible Acute Coronary Syndrome,”1 published online December 13, 2017, there was an error in the fifth paragraph of the Methods section, regarding the range of the tropnin T assay. The fourth sentence of the fifth paragraph should read “It has a specified range of 6 ng/L to 10 000 ng/L (all platforms) and a limit of quantification (LoQ) of 6 ng/L.” This article was corrected online.
