“…In the high-sensitivity protocol development process, some manufacturers reported modifications able to decrease assay responsiveness against HAMAs when using chimeric antibodies in their immunoassay [47]. Furthermore, analytical limits have already been described -chiefly haemolysis interference potentially inducing over-or under-estimation, depending on the assay [48]. Visually examining the specimen tube can provide an evaluation of sample quality, especially for samples drawn through the intravenous catheter lines used in intensive care units.…”

“…34 A number of laboratories surveyed do not report troponin results that breach the set haemolysis limit and many request an urgent repeat sample. Clearly, it is necessary to avoid reporting potentially erroneous results, however the risk of missing or delaying reporting a clinically significant result should be considered.…”

“…Per esempio, due articoli di recente pubblicazione hanno dimostrato che l'emolisi può alterare significativamente alcune determinazioni di troponina, per lo più metodo-dipendenti. Nel primo studio è stato osservato un calo fino al 50% della concentrazione di troponina T ad alta sensibilità e, contestualmente, un aumento fino al 576% di troponina I per valori di emolisi elevati, superiore a 600 mg/L [27]. Nel secondo studio i risultati sono sovrapponibili, con variazioni significative della determinazione delle troponine per valori di emolisi superiori a Tabella 3 Interferenza dell'emolisi sui test di laboratorio.…”
