High-sensitivity troponin I assay available in the U.S.
July 2018—Beckman Coulter Diagnostics received 510(k) clearance from the Food and Drug Administration for its new high-sensitivity troponin assay, Access hsTnI, for use on the Access 2, DxI, and the entire Access family of immunoassay systems. Access hsTnI demonstrates less than 10 percent CV at the upper reference limits for men and women and detects troponin in more than 50 percent of the healthy population. In an independent study, Access hsTnI detected more than 99 percent of troponin values for healthy men and women (Pretorius CJ, et al. Clin Biochem. 2018;55:49–55). “Beckman Coulter’s high-sensitivity cardiac troponin I assay can measure very low cardiac troponin concentrations with excellent precision. This test may help physicians with both the early diagnosis of myocardial infarction and future risk stratification in and outside the acute coronary syndrome setting,” Peter Kavsak, PhD, associate professor, Department of Pathology and Molecular Medicine, McMaster University, said in a statement.
