Abstract
Point-of-care (POC) testing offers the opportunity to provide more rapid measurement of cardiac biomarkers in the environment in which clinical decisions about patient management are made. The technology of POC testing utilizes whole blood to measure one or more analytes including cardiac biomarkers such as creatine kinase-MB isoenzyme, myoglobin, cardiac troponins T and I, and B-type natriuretic peptide. Measurement methods include immunochromatographic separation usually combined with a quantitative reader, dedicated heterogeneous immunoassay systems, and those suitable for POC and emergency laboratory testing. Analytic performance of these systems approaches but does not always equal those of conventional laboratory methods. Evaluation of POC testing of cardiac biomarker measurement has shown good analytic and clinical diagnostic performance. These systems are entirely suitable for rule-in diagnosis of myocardial infarction (MI). Although POC testing has also been shown to be suitable for rule-out strategies, there is a lack of studies comparing POC testing with laboratory measurements for diagnosis using updated criteria for acute MI or for prognosis. Although POC testing is faster, there is only limited evidence that the speed and convenience of these systems can have a direct impact on outcome measures such as treatment selection or length of stay. More work is needed in this area.
