Determination of high‐sensitivity cardiac troponin T upper reference limits under the improved selection criteria in a Chinese population

Background There is no common consensus on how to define the reference population for determination of high‐sensitivity cardiac troponin (hs‐cTn) upper reference limit (URL). This study aimed to establish 99th percentile URLs of hs‐cTnT under both 2018 AACC/IFCC criteria and improved selection criteria for further judging whether two URLs are different.
