Choline has been identified as a promising marker of coronary inflammation, plaque destabilisation and ischaemia. We sought to evaluate plasma choline levels for rapid confirmation or exclusion of acute myocardial infarction (AMI) in the Emergency Department (ED) and for predicting major adverse cardiac events (MACE). ⋯ Plasma choline, measured at the time of ED presentation, is not a diagnostic marker of AMI but predicts AMI within 6 months. While plasma choline failed to predict MACE, WBCho was predictive and warrants further evaluation.

Laboratory testing, a highly complex process commonly called the total testing process (TTP), is usually subdivided into three traditional (pre-, intra-, and post-) analytical phases. The majority of errors in TTP originate in the pre-analytical phase, being due to individual or system design defects. In order to reduce errors in TTP, the pre-analytical phase should therefore be prioritized. ⋯ Automated systems to prevent medical personnel from drawing blood from the wrong patient were introduced commercially in the early 1990s. Correct patient identification and test tube labelling before phlebotomy are of extreme importance for patient safety in TTP, but currently few laboratories are interested in such products. At San Bassiano hospital, the implementation of advanced information technology and robotics in the pre-analytical phase (specimen collection and pre-analytical sample handling) have improved accuracy, and clinical efficiency of the laboratory process and created a TTP that minimizes errors.
