The focus of cTn testing in suspected NSTEMI is rapid exclusion of myocardial injury as a cause of ischemic symptoms to remove them from the emergency department (ED) and reduce the overcrowding associated with adverse outcomes.

There is the opportunity to optimize the diagnosis by serial cTn sampling to distinguish acute cTn increases, a rising and/or falling concentration, or chronic, non-changing increased concentration. Most patients with a final diagnosis of ACS, rather than nonischemic chest pain, fall into medium or low risk ACS groups, with coronary intervention recommended within 24 h in the medium risk ACS group and 72 h in the low-risk ACS group. Even in patients presenting with suspected NSTEMI, only the highest ACS risk group, defined entirely by clinical criteria and the ECG, require immediate coronary intervention. Guideline recommended measurement of cTn by a high-sensitivity (hs) method is only used to guide management in patients without STEMI. POC testing for cardiac troponinĬurrent recommendations for the management of patients with suspected acute coronary syndrome (ACS), divides patients into two groups based on the initial electrocardiogram (ECG): (a) those with ST segment elevation myocardial infarction (STEMI) and (b) those where the initial diagnosis is unclear.

Only the desktop and portable instruments will be discussed further, as central laboratory instrumentation is already covered adequately by current guidelines. Such devices may be used at the patient bedside, deployed on a desktop or may be used for testing outside the hospital environment. They are usually, but not inevitably, capable of fully autonomous function as they contain an internal power supply which may use rechargeable or non-rechargeable batteries. Portable instruments which can be easily transported by one individual in person or on a cart/trolley. On the basis of this definition, pragmatically, POC testing can be divided into three classes of instrumentation. This definition means, theoretically, any instrument can be used for POC testing. Point of care testing is defined as diagnostic testing that is performed at or near to the site of the patient, performed by non-laboratory personnel, with the prompt result leading to a potential change in the care of that patient. The focus is on hs-cTn POCT methods, as only these are suitable for the rapid algorithms discussed in the article. The present IFCC C-CB educational report focuses on recommendations for appropriate use, analytical performance, and gaps in clinical studies related to the use of cTn by point of care (POC) measurement, often referred to as a point of care testing (POCT). The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Committee on Clinical Applications of Cardiac Bio-Markers (C-CB) has provided evidence-based educational resources to aid and improve the understanding of important analytical and clinical aspects of cardiac biomarkers. POCT workflow integration includes location of the instrument, assignment of collection and testing responsibility to (non-lab) staff, instrument maintenance, in-service and recurrent training, quality control, proficiency assessments, discrepant result trapping, and troubleshooting and inventory management. The use of high-sensitivity (hs)-cTn POC devices in accelerated diagnostic protocols used in emergency departments or outpatient clinics investigating acute coronary syndrome has the potential for improved efficacy, reduction of length of stay and reduced costs in the health care system.
