Access hsTnI (High Sensitivity Troponin I Assay)

High-quality

• Delivers quality results with a new robust design to minimize the effects of pre-analytical variability and known interferences
• Demonstrates optimal precision at concentrations ~10x lower than previous generations of assays

Accurate

• Accurately identifies ≥94% of true acute myocardial infarction (AMI) patients in as little as one hour after presentation
• Enables more accurate identification of women with AMI by providing separate sex-specific upper reference limits
• Provides >99% confidence in ruling out AMI when a patient’s troponin result is below the URL

Timely

• Enables easier interpretation of test results by using whole-number reporting
• Increases testing flexibility as the only high-sensitivity assay to use either plasma or serum samples

Access hsTnI delivers tangible advances in patient care

A multicenter prospective study to establish the 99th percentile URL in a population of healthy adults was conducted. Study participants had no known cardiovascular diseases, other acute or chronic diseases, or infections. (See Tables 1 and 2.)

Access hsTnI provides sex-specific cutoff values.

hsTnI Toolbox

Adoption of high-sensitivity troponin assays that meet International Federation of Clinical Chemistry and Laboratory Medicine guidelines is recommended by the recently released Fourth Universal Definition of Myocardial Infarction. These assays have higher analytical precision at lower concentrations, yielding greater clinical sensitivity for myocardial injury, including new insights into troponin levels in women thanks to sex-specific reference ranges. The assays also support shorter interval serial measurement strategies for managing patients with possible acute myocardial infarction in the emergency department.

Many stakeholders in the healthcare system are impacted by these insights, including laboratorians, nurses, cardiologists and emergency medicine physicians. Understanding and addressing the unique concerns of all stakeholder groups is key to the implementation of these new assays. The hsTnI Toolbox is a curated set of customer self-service tools to aid in the implementation of the Access hsTnI assay.
