All investigations, clinical information, and outcomes from presentation to 30 days were independently reviewed by 2 adjudicators (A.S. and A.A.). Rapid advances in immunoassay technologies and the international adoption of traceable troponin calibration standards have allowed manufacturers to develop and calibrate troponin assays with unprecedented analytic sensitivity and precision.
