RT Journal Article SR Electronic T1 Point-of-care testing with high-sensitivity cardiac troponin assays: the challenges and opportunities JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 861 OP 866 DO 10.1136/emermed-2021-211907 VO 39 IS 11 A1 Louise Cullen A1 Paul O Collinson A1 Evangelos Giannitsis YR 2022 UL http://emj.bmj.com/content/39/11/861.abstract AB Methods to improve the safety, accuracy and efficiency of assessment of patients with suspected acute coronary symptoms have occupied decades of study and have supported significant changes in clinical practice. Much of the progress is reliant on results of laboratory-based high-sensitivity cardiac troponin assays that can detect low concentrations with high precision. Until recently, point-of-care (POC) platforms were unable to perform with similar analytical precision as laboratory-based assays, and recommendations for their use in accelerated assessment strategies for patients with suspected acute coronary syndrome has been limited. As POC assays can provide troponin results within 20 min, and can be used proximate to patient care, improvements in the efficiency of assessment of patients with suspected acute coronary syndrome is possible, particularly with new high-sensitivity assays.
