The Growing Impact of Cardiac Biomarkers in Clinical Chemistry.

Clinical chemistry measurements and calculations take into account an expansive set of analytes that reflect cardiac, liver, kidney, and other biological functions. Several of these discrete analytes are considered biomarkers, defined by Strimbu and Tavel as “a broad subcategory of medical signs [that are] objective indications of medical state observed from outside the patient which can be measured accurately and reproducibly.” In the case of cardiac biomarkers, the most common analytes are creatine kinase (CK), lactate dehydrogenase (LDH), and troponin (TNI). There are pros and cons to using these common chemistry tests as definitive cardiac biomarkers. However, other chemistry analytes and even some non-laboratory tests have been identified as potential cardiac biomarkers. Providing clinicians with accurate and thorough testing is important in contributing to diagnosis and ultimately to positive patient outcomes.
