1 - Program Overview

Many cardiac marker determination methods are currently available on the market. The external quality assessment of cardiac markers helps clinical biologists to assess their own analytical methods so provides information on the differences in results obtained with the various techniques available.

Depending on the needs revealed by the survey results, additional studies will be performed to improve the understanding and interpretation of the results of this EQA.

The great number of laboratories taking part in the cardiac marker program emphasizes the importance of these biomarkers in clinical diagnostics.
