Study purpose/objective:~Determine the sex-specific 99th percentile upper reference limits (URLs) for the Mindray hs-cTnI assay using the CL-1200i Instrument.~Method comparison across the dynamic range of cTnI concentrations between the Mindray hs-cTnI assay and the Abbott Alinity hs-TnI assay used in clinical practice at Hennepin Healthcare/Hennepin County Medical Center.~Evaluate the clinical performance of the Mindray hs- cTnI measuring system for the diagnosis of myocardial infarction (MI), for early rule out MI and myocardial injury, and assessment of 30-day safety outcomes in patients presenting to the emergency department (ED) in whom serial cTnI measurements (0h, 2h, 4h, 6h) are obtained on clinical indication at Hennepin Healthcare / Hennepin County Medical Center (Minneapolis, MN USA) to rule-in and rule-out MI.
The Mindray High Sensitivity Troponin-I Measurement System is an in vitro diagnostic test for the quantitative determination of high sensitivity cardiac troponin I (hs-cTnI) in human serum or plasma.~The Mindray High Sensitivity Troponin-I Measurement System is to be used as an aid in the diagnosis and rule out of acute myocardial infarction (AMI).
