The i-STAT High Sensitivity Troponin I (i-STAT hs-TnI) test is an in vitro diagnostic test for the quantitative measurement of cardiac troponin I (cTnI) in whole blood or plasma samples using the i-STAT 1 Analyzer or i-STAT Alinity Instrument in point of care or clinical laboratory settings. The hs-TnI test is intended to be used as an aid in the diagnosis of myocardial infarction (MI). The objective of this study is to evaluate the clinical performance of the i-STAT hs-TnI test using the investigational i-STAT hs-TnI Cartridge with the i-STAT 1 Analyzer and i-STAT Alinity Instrument for subjects presenting to the emergency department (ED) with chest discomfort or equivalent ischemic symptoms suggestive of Acute Coronary Syndrome (ACS). The clinical evaluation will use prospectively collected whole blood specimens from subjects presenting to the ED with chest discomfort or equivalent ischemic symptoms suggestive of ACS.
