Access hsTnI (High Sensitivity Troponin I) Assay

Confidently report accurate results with the first true high-sensitivity troponin I assay cleared by the FDA

Access hsTnI is a true high-sensitivity troponin assay that demonstrates <10% CV at the upper reference limits (URL) for men and women and detects troponin in >50% of the healthy population. In an independent study, the assay detected troponin in >99% of healthy men and women.1 Access hsTnI provides reliable test results that your physicians can count on to make faster and more confident decisions about patient management.

The Access hsTnI assay:  

  • 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
  • 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
  • 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
 

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.)
