Cardiac Testing Educational Material

A variety of resources to help keep you informed of the latest topics in cardiovascular disease testing.


Siemens Healthineers is pleased to offer a series of educational videos focusing on the clinical utility of high-sensitivity troponin I. Hear leaders in the area of cardiovascular disease and laboratory diagnostics discuss the importance of implementing a high-sensitivity troponin I assay into their facility.

Understanding Findings of Sex-specific 99th Percentile URLs for High-sensitivity Cardiac Troponin Assays Derived from Universal Sample Bank

Selection of healthy reference populations and definition of exclusion criteria for deriving 99th percentiles for high-sensitivity cardiac troponin assays used in clinical practice and research vary considerably in the literature. We discuss the Universal Sample Bank findings regarding their clinical implications:

a) Sex-specific 99th percentiles varied according to the statistical method and hs-cTn assay used.

b) Not all assays provided measurable concentrations for women to qualify as hs assays.

c) Surrogate exclusion criteria used to define normality tended to lower 99th percentiles. Participants will learn that the decision concentrations used can affect diagnostics, risk-outcome assessments, and analytical characteristics.
