*PCR conducted using XGEN MASTER COVID-19 Kit (Mobius Life Science, Inc, N, nucleocapsid protein gene; ORF, open reading frame.
†Cycle threshold value is considered positive if both viral genes are <38.
‡PCR is selective for human RNaseP gene as a control for sample integrity.
§Insufficient sample.
