Bayer Diagnostics Announces First Fully-Automated High Sensitivity and High Precision Troponin Assays

TnI-Ultra(TM) Assays Contribute to Higher Levels of Sensitivity and Precision Increasing Confidence in Management of Patients Suspected of Myocardial Infarctions (MI)

TARRYTOWN, N.Y., Jan. 31 (HSMN NewsFeed) -- Bayer HealthCare, Diagnostics Division, a member of the Bayer Group (NYSE: BAY ), announced today that they have received FDA clearance on two new Troponin-I assays (TnI-Ultra(TM)). The TnI-Ultra assays are the first fully-automated Troponin assays meeting the European Society of Cardiology/American College of Cardiology recommendation of a less than or equal to 10% level of imprecision at the 99th percentile of a healthy population. Meeting the ESC/ACC criteria is a key attribute in the definition of a high sensitivity Troponin test. The TnI-Ultra assay has been cleared on Bayer's ADVIA IMS® 800i and ADVIA Centaur® Immunoassay System. These assays aid physicians in the diagnosis of Myocardial Infarction (MI) and the assessment of risk in patients with acute coronary syndrome.

The ADVIA IMS and the ADVIA Centaur Immunoassay TnI-Ultra assays have the same 99 percentile value and show the equivalent precision at this very low level. This strong concordance between assays allows for equivalent results in core and satellite laboratory situations. The high degree of precision seen with the TnI-Ultra assays is expected to show an increased level of accuracy, contributing to improved patient care in those suspected of MI.

Bayer has a strong heritage of TnI "firsts" as they were also the first to receive FDA clearance of their cTnI assay in the risk stratification of patients with non-ST segment elevation acute coronary syndromes.

"The addition of TnI-Ultra to the cardiovascular menu meets customers' needs for a troponin assay that meets ESC/ACC guidelines and strengthens Bayer's already impressive portfolio -- which includes CK-MB, Myoglobin, Homocysteine, and BNP -- allowing for workstation consolidation and rapid turnaround of results on highly productive Immunoassay systems," said Tom Warekois, Senior Vice President of Global Strategic Marketing for Bayer HealthCare's Diagnostics Division.

Prevalence of Heart Attacks
