When a patient comes to the emergency department with a suspected acute coronary syndrome, the speed and accuracy of the diagnostics have a critical impact on outcome and cost of care. (See Figure 1.)

High-sensitivity troponin tests drive fast decision making by:
In addition, high-sensitivity troponin assays can:
More sensitive cardiac troponin tests enable greater confidence in results, accelerate a clinician's ability to rule in (or rule out) myocardial infarction, and provide efficiency improvements in cardiac patient management. With more sensitive assays, more rapid serial sampling is now possible. In addition, they enable faster decisions about small changes in low levels of troponin over shorter periods of time.
The 2015 ESC Guidelines (see Figure 2) recommend sampling at 0 and 3 hours, integrating testing with detailed clinical assessment, and a mandatory 12-lead ECG and repeat blood sampling when a patient experiences recurring chest pain.2
Figure 2: 0/3 Hour Protocol Described By 2015 ESC Guidelines
Provide reliable results that physicians can use with confidence to make decisions about patient management. The Access hsTnI assay offers much greater precision at very low levels of troponin, which may help physicians may help interpret small changes in low levels of troponin over shorter periods of time. In addition, Access hsTnI utilizes a new robust design to minimize the effects of pre-analytical variability and known interferences. You can run Access hsTnI on any Access 2 or DxI series immunoassay analyzer.
