Abstrakt: ADVIA Centaur SARS-CoV-2 Antigen (COV2Ag) Assay (Siemens Healthineers) was evaluated for SARS-CoV-2 detection. A total of 141 nasopharyngeal samples were analyzed by this technique and results were compared with those obtained by quantitative reverse-transcription polymerase chain reaction (RT-PCR). The overall sensitivity and specificity of the test were 68.70% and 70%, respectively. Regarding cycle threshold (Ct) values, the COV2Ag test showed a sensitivity of 93.75% and 100% for nasopharyngeal samples with Ct < 25 and < 20, respectively. ADVIA Centaur COV2Ag Assay is a useful, automated, and rapid technique for early SARS-CoV-2 diagnosis and isolation of the infected individuals, avoiding its transmission.
