Ad interim SIBioC recommendations for serological assessment of SARS-CoV-2 infection

ABSTRACT

The recent pandemic outbreak caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and associated with the pathology called COVID-19 (coronavirus disease 2019), has now become one of the most strenuous health care challenges since the emergence of the three pandemics caused by influenza viruses during the past century. Throughout the clinical decision-making of COVID-19, laboratory tests are essential for supporting the screening, diagnosis, prognostication and therapeutic monitoring of this severe infectious disease. Serological testing, that reflects the humoral immune response developing after interaction between the host and the virus (or its components), enables to garner a vast array of clinical information which can be especially used in seroprevalence or seroconversion studies. To this end, the Task Force on COVID-19 of the Italian Society of Clinical Biochemistry and Clinical Molecular Biology (SIBioC) has endorsed a series of technical, practical and clinical ad interim recommendations, aimed at facilitating and optimizing the introduction, clinical usage and governance of SARS-CoV-2 serological immunoassays in routine practice.
